Safety classification information
Note: 1. The actuation of the interlock must be compared with the external OSSD enabler. If a shut-down now occurs due to an unintentional
unlocking this is detected by an external diagnostic.
2. The safety consideration of the guard locking function only applies for monitored safety door switch D41L-@Y.
3. If for a certain application the power to unlock type of a safety door switch cannot be used, then for this exception the power-to-lock type
of a safety door switch can be used if additional safety measure need to be realized that have an equivalent safety level.
4. The safety analysis of the guard locking function refers to the component safety door switch as part of the complete system.
In the event of a fault resulting in the unlocking of the guard locking, this is detected by the safety outputs Y1/Y2 of the safety door switch
switch off. When such a fault occurs the protection equipment may open immediately, just once, before the safe condition of the machine
is reached. The system reaction of category 2 allows that a fault can occur between tests causing the loss of the safety function which
is detected by the test.
5. If multiple safety door switches are involved in the same safety function, the PFH values of the individual components must be added.

Wiring Examples
The application examples shown are suggestions. They however do not release the user from carefully checking whether the safety door switch
and its set-up are suitable for the individual application.
The power supply for the safety door switch must provide protection against permanent overvoltage. To that effect, stabilized PELV supply units
must be used. The safety outputs can be directly connected in the safety circuit of the control system. For applications of PL e / safety category 4
in accordance with ISO 13849-1, the safety outputs of safety door switch or safety door switch of the chain must be connected to a safety controller
or safety relay unit of the same Safety Category.
If the safety door switch is connected to the safety input of a safety controller or safety relay unit, the controller must have a dual-channel monitoring
time of at least 100 ms and the accepted test pulse duration of at least 1 ms. Also, the cross-wire-short monitoring function must be disabled.
D41L series connection example
When connecting multiple safety door switches in series, apply 24 VDC to safety inputs X1 and X2 on the Nth unit, as shown in the figure below.
Connect safety outputs Y1 and Y2 to safety inputs X1 and X2 of the following safety door switch.
Connect safety outputs Y1 and Y2 of the first unit to the safety controller or safety relay unit.
Connect the auxiliary output to the PLC, etc.
When connecting a single safety door switch to the safety controller or safety relay unit, apply 24 VDC to safety inputs X1 and X2 in the same
manner as the Nth unit shown below, and then connect safety outputs Y1 and Y2 to the safety controller or safety relay unit.

Release
Manual Release
For the machine set-up, the safety door switch can be unlocked in a de-energized condition.
The safety door switch is unlocked by turning the manual release in the position (unlock).
The normal locking function is only restored after the manual release has been returned to its original position (lock).
After being put into operation, the manual release must be sealed by means of the seal, which is included in delivery.
Emergency exit (D41L-@@D@E-N2)
To activate the emergency exit, turn the red lever in the direction of the arrow to the end stop. The safety outputs switch off and the guard system
can be opened. The blocked position is cancelled by turning the lever in the opposite direction. In the unlocked position, the guard system is
secured against unintentional locking.
With variants that have emergency-exit, the red lever is included with delivery.
The lever should be fastened to the position intended with the supplied screws before first being used.
The lever should be installed on the unlocking triangle in such a way that the arrow on the triangle and the lever pivot are congruent. The installation
of the lever is possible on both sides.
The opposite is to be sealed with the seal included with delivery.
Fitting and actuation only from within the hazardous area.

Teaching
Individually coded safety door switch and actuators will require the following teach-in procedure:
1. Keep the actuator away from the detection range and switch the safety door switch's voltage supply off and back on.
2. Introduce the actuator in the detection range. The teach-in procedure is signaled at the safety door switch, green LED off, red LED on, yellow
LED flashes (1 Hz).
3. After 10 seconds, the yellow LED gives brief cyclic flashes (3 Hz). Switch off the supply voltage of the safety door switch. (If the voltage is not
switched off within 5 minutes, the safety door switch cancels the teach-in procedure and signals a false actuator by 5 red flashes).
4. Switch the supply voltage back on. The actuator must be detected once more in order to activate the taught actuator code.
In this way, the activated code is definitively saved.
For ordering suffix D41L-1, the thus executed allocation of safety door switch and actuator is irreversible.
When the above procedure is attempted with a D41L-1 which already completed teaching, the teaching procedure will not start.
For ordering suffix D41L-2, the teach-in procedure for a new actuator can be repeated an unlimited number of times. When a new actuator is taught,
the code, which was applicable until that moment, becomes invalid.
Subsequent to that, the safety outputs will be disabled for ten minutes, thus providing for an increased protection against intentional tampering.
The green LED will flash until the expiration of the time (10 minutes) of the enabling inhibit and the detection of the new actuator. In case of power
failure during the lapse of time, the 10-minutes tampering protection time will restart.
When the above procedure is attempted with a combination of D41L-2 and actuator which already completed teaching, the teaching procedure will
not start.

Operating Principle
Operating Principle
Magnet control
In the power-to-unlock version of the D41L, the safety door switch is
unlocked when the Solenoid Control signal (= 24V) is set. In the
power-to-lock version of the D41L, the safety door switch is locked
when the Solenoid Control signal (= 24 V) is set.
If the risk analysis indicates the use of a monitored interlock then a
variant with the monitored interlock (D41L-@Y) is to be used, labelled
with the symbol.
The actuator monitoring variant (D41L-@Z) is a safety switch with an
interlock function for process protection.
Mode of operation of the safety outputs
In the standard D41L variant, the unlocking of the safety door switch
causes the safety outputs to be disabled. The unlocked guard door
can be relocked as long as the actuator is inserted in the D41L safety
door switch; in that case, the safety outputs are re-enabled.
The guard door must not be opened.
In the D41L-@Z version, only the opening of the guard door causes
the safety outputs to be disabled.
If the safety outputs are already enabled, any error that does not
immediately affect the functionality of the safety door switch (e.g. too
high ambient temperature, interference potential at the safety outputs,
cross-wire short) will lead to a warning message, disabling of the
auxiliary output and a delayed shutdown of the safety outputs.
(Refer to Troubleshooting on page 17.)
Safety outputs are disabled if the error warning is active for 30
minutes. The signal combination, auxiliary output disabled and safety
channels still enabled, can be used to stop the production process in
a controlled manner. After the rectification of the error, the error
message is reset by opening the corresponding guard door.
Latching Force Adjustment
Adjustment of the latching force
In order to enable trouble-free functionality of the device, the rotary
handle must be in position I or II when the guard door is open.
In the intermediate positions, locking is impossible.
The latching force is changed by turning the rotary handle by 180°.
In position I, the latching force is approx. 25 N.
In position II, the latching force is approx. 50 N.
Diagnostic Function
Diagnostic LEDs
The safety door switch signals the operating condition, as well as
errors through 3-color LEDs.
Green (Power): Supply voltage on
Yellow (Status): Operating condition
Red (Fault): Error (refer to Table 2)/ flash codes red diagnostic LED
Safety door switch with conventional auxiliary output
The auxiliary output OUT can be used for central visualization or
control functions, e.g. in a PLC.
The auxiliary output is not a safety-related output.

Mounting
For the correct fixing of the safety door switch and the actuator, two
mounting holes for M6 screws are provided
(tightening torque: 6 to 7 N•m).
Any mounting position. The system must only be operated with an
angle of ≤2° between the safety door switch and the actuator.
The actuator must be permanently fitted to the safety guard and
protected against displacement by suitable measures
(tamperproof screws, gluing, drilling of the screw heads, pinning).
Actuating directions
The diagrams show a closed guard system with a set latching force of 50 N
To avoid any interference inherent to this kind of system and any
reduction of the switching distances, please observe the following
guidelines:
• The presence of metal chips in the vicinity of the safety door switch
is liable to modify the switching distance.
• Keep away from metal chips.
Provide for a sufficient insertion of the actuator into the rotary handle.
Minimum distance between two safety door switches as well as other
systems with same frequency (125 kHz)
The minimum distance from metallic securing surfaces to the face
side "A" and underside "B" of the device is 5 mm.
Accessories for installation (Mounting plate (D41L-MP))

Troubleshooting
Errors
Errors that no longer guarantee the function of the safety door switch (internal errors) cause the safety outputs to be disabled immediately. Any
error that does not immediately affect the safe functionality of the safety door switch (e.g. too high ambient temperature, interference potential at
the safety outputs, cross-wire short) will lead to a warning message, disabling of the auxiliary output and a delayed shutdown of the safety outputs.
(Refer to Table 2.)
After fault rectification, the error message is reset by opening and re-closing the corresponding guard door.
Error warnings
A fault has occurred, which causes the safety outputs to be disabled after 30 minutes (LED "fault" flashes, see Table 2). The safety outputs initially
remain enabled. This signal combination, auxiliary output disabled and safety channels still enabled, can be used to stop the production process
in a controlled manner. An error warning is deleted when the cause of error is eliminated.

1. Do not drop the product to the ground or expose to excessive
vibration or mechanical shocks. Doing so may damage the product
and cause failure.
2. Do not store or use the product under the following conditions.
Doing so may damage the product and cause failure.
1) At ambient operating temperatures out of the range of 0 to 60°C
2) At ambient storage temperatures out of the range of -10 to 90°C
3) At relative humidity of 93% or more
4) In direct sunlight
5) Under drastic temperature changes
6) In high humidity that causes condensation
3. Keep the product away from oil or solvent. Oil or solvent make the
marking on the product illegible and cause deterioration of some
parts.
4. Do not use in an environment with corrosive gas.
5. The product may not operate normally in the vicinity of devices that
generate strong radio waves or magnetic fields, such as RFID
systems, proximity sensors, motors, inverters, and switch-mode
power supplies. If the device is used in the vicinity of such devices,
check the effect before use.
6. Installing the switch and the actuator on a metallic material may
affect the operating distance. If installation on a metallic material
is necessary, be sure to check the effect on the operating distance
before use.
7. Tighten the screws with a specified torque.
8. Use the wires specified by OMRON to wire the product.
(Refer to Connection.)
9. Do not extend the cables in excess of the specification of this
product. Carry out electrical connection according to the wiring
examples shown in this document and verify the correct operation
of the product.
10.Do not pull or bend the cable excessively. A disconnection may
cause a malfunction.
11. Risk time remains unchanged by series connection. However,
carry out electrical connection according to the wiring examples
shown in this document.
12.Be sure to inspect the product daily and every 6 months. Failure to
do so may cause a system failure and serious injury.
13.When determining the safety distance, take into account the delay
of the output of the product caused by the response time. Failure
to do so may cause the operator to reach the hazardous source
before the machine is stopped, resulting in serious injury.
14.During installation, make sure that the safety door switch does not
come in contact with the actuator due to rattling of the guard door.
(The performance of the product may be degraded by a collision
caused by opening or closing the guard door.)
15.Install the product so that the LED indicators of the safety door
switch are as visible as possible. Misinterpreting the status of the
safety door switch may result in danger.
16.Do not use the product at an altitude of 2,000 m or higher.
17.Do not connect a product different from this product in series with
this product. Doing so may disturb waveforms of the input and
output signals, leading to loss of the safety function.
18.Do not use the product in the water or continuous water exposure
environment. Doing so may cause water to leak into the product.
(The degree of protection does not guarantee the protection under
continuous water exposure environment.)
19.Do not tamper the product with a replacement actuator. Store
replacement actuators in a safe place where they cannot be easily
reached.
20.Build a safety system using the outputs of both Safety Outputs 1
and 2. Wiring with only one safety output may lead to loss of the
safety function due to a single failure.
21.Wiring should meet the requirements specified in Section 9.4.3 of
IEC 60204-1 to prevent malfunction due to ground faults in the
safety output lines.
22.In the power-to-lock type, close the door before energizing the
safety door switch.
23.In the power-to-lock type, the safety door switch is locked only
when the solenoid is energized. If the solenoid is de-energized due
to a sudden power failure, the operator may be exposed to a
hazardous source. Use the power-to-lock type only for process
protection.
24.Do not use the emergency-exit type for switching the machine on
and off. Doing so may place operators at risk due to being trapped
inside or unexpected operation of the machine.
25.Install the emergency-exit type so that it cannot be operated from
outside a safety zone.
26.Do not apply excessive force on the actuator while the actuator is
inserted into the switch body or do not drop the product. Doing so
may deform the actuator or damage the switch body.
27.The safety function may not operate normally due to a malfunction
of the wiring, setting, or switch, and the machine may continue to
operate, which may result in personal injury. Make sure that the
safety function works before starting operation.
28.The current consumption of the safety door switch is different
between when it is turned on and when it is in a normal operation.
Apply the supply voltage to the safety door switch in consideration
of the voltage drop in the wiring.
29.Do not turn beyond the latching point. After being put into
operation, the manual release must be secured by closing the flap
cover with the seal, which is included in delivery.

from power supply when replacing the product. Failure to do so
may cause unexpected operation of devices connected to the
product.
33.Install the product to a position near a handle of the guard door.
Installing it near a hinge may cause the locking part of the product
to receive larger load than the operating force, leading to damage
to the locking mechanism.
34.Do not try to disassemble, repair, or modify the product. Doing so
may cause loss of the safety function.
35.Do not operate the product in an environment with flammable or
explosive gas.
