2 On safety
This section concerns your own safety and the safety of the system operator.
bPlease read this section carefully before you begin working with the IN4000 Stand‐
ard series of inductive safety switches, or the machine protected by these safety
switches in conjunction with the corresponding protective devices.
National and international legal regulations apply to the use/installation of the IN4000
Standard series of safety switches as well as to their commissioning and recurring
technical inspections, in particular
•the Machinery Directive,
•the EMC Directive,
•the Work Equipment Directive,
•the safety regulations, and
•the accident prevention regulations and work safety regulations.
2.1 Qualified safety personnel
The safety switches must only be installed and commissioned by qualified safety per‐
sonnel. A person is considered qualified safety personnel if he/she
•has taken part in adequate technical training
and
•has been instructed by the machine operator in machine operation and the appli‐
cable safety guidelines
and
•can access these operating instructions.
2.2 Applications of the safety switches
The IN4000 Standard series of safety switches are inductive safety proximity switches
that are actuated by metal in a non-contact manner. The safe state is the de-energized
state.
The IN4000 Standard series of safety switches and the corresponding machine or
system controller can be used, for example, to protect movable physical guards in such
a way that:
•the dangerous state of the machine or system can only be switched on when the
protective devices are closed.
•a stop command is triggered if a protective device is opened while the machine is
running.
For the controller, this means that:
•switch-on commands that result in dangerous states may only be activated when
the protective devices are in the protective position,
and
•dangerous states must be ended before the protective devices are moved out of
the protective position.
Before using the safety switches, a risk assessment must be carried out on the
machine.
Intended use also includes compliance with the relevant requirements for installation
and operation.

WARNING
Safety switches must not be circumvented, rotated away, removed, or rendered ineffec‐
tive in any other way. Their contacts must not be bridged.
The inductive safety switches respond to metallic objects. Other metallic objects that
are not intended to trigger the safety function must not be placed on the sensing face
of the safety switches under any circumstances. Appropriate measures must therefore
be taken to prevent this.
Please observe the installation measures according to ENISO14119.

3 Product description
3.1 IN4000 Standard Series safety switches
The IN4000 Standard series of safety switches are based on the same principle of
operation, but differ in their design, installation method, response ranges, and classifi‐
cation.
The IN40-D0101K safety switch has a cuboid housing with an alignable active sensor
face. It can also be installed flush or flush on one side, except in steel.
The IN40-D0303K and IN40-D0202K safety switches are enclosed in a cylindrical
housing and are not suitable for flush or one-sided flush installation.
The IN40-D0304K safety switch is enclosed in a cylindrical housing and is suitable for
flush installation.
3.2 Features and principle of operation
The IN4000 Standard series of safety switches are typically used for safe posi‐
tion detection, as is the case, for example, when monitoring a movable protective
device. The sensor detects the presence of metal. In order to meet the requirements
against easy manipulation, the switching range of the sensor is monitored in time and
space.
Its status can be read directly on the sensor or the protective device by means of
LEDs. Errors, such as a coil break, short-circuit or wire break are detected by the
self-monitoring function of the sensor.
The safety switch can be connected directly to a safe PLC or to a SICK safety controller,
e.g., Flexi Classic or Flexi Soft.
The IN4000 Standard series of safety switches can be cascaded (see "Series connec‐
tion of inductive safety switches", page 21).
Information on connection can also be found in the operating instructions of the safety
controller used (e.g., Flexi Classic or Flexi Soft).

After actuation in the close range, either the supply voltage must be interrupted or the
actuator must be brought into the assured switch-off distance for more than 2s before
it can be enabled again.
The enable zone depends on the type of safety switch and the material and shape of
the actuator. Using other actuators (material, shape) results in a different enable zone.
Typically, the following enable zone is achieved at an ambient temperature of 20°C
with non-flush installation of the safety switch using a standard plate according to
EN60947--5-2 (45 × 45 × 1mm3 for IN40-D0101K and
IN40-D0202K or 24 × 24 × 1mm3 for IN40D03..) and with different materials:

3.4.1 Displays in operating mode
The yellow signal LED lights up immediately or after a time delay, depending on the
duration of the preceding de-actuation, when an actuator enters the enable zone.
NOTE
Regardless of the behavior of the yellow LED, the output always switches within the
normal response times without any additional delay.
•If the actuator is in the enable range when the supply voltage is switched on, the
yellow signal LED switches after a time delay of 5s.
•If the actuator was ≥2s away from the sensor at the assured switch-off distance
and is then brought back into the enable zone, the yellow signal LED switches after
a delay of 3s.
•If the actuator was <2s away from the sensor at the assured switch-off distance
and is then brought back into the enable zone, the yellow signal LED switches
without a time delay.
•If the actuator is brought to the assured switch-off distance from the sensor, the
yellow signal LED switches off without delay.
•If the actuator is brought into the close range, the yellow signal LED switches off
after a delay of 2s.

Permissible test pulse width 1.0ms
If the actuator is in the enable zone and no sensor error is present, the clock input
signal is passed on to the output after a delay time of td. The output characteristics are
compatible with the input characteristics according to EN 61131-2 type 1 or 2:

IN40-D0101K: 50mA
IN40-D03..: 30mA
IN40-D0202K: 30mA
If the actuator is outside the enable zone, the output is switched off (logical “0”; safe
state).
Any deviation from the timing sequence, including continuous logical “1”, represents an
error.
WARNING
Cross-circuits are detected by the safety switch and lead to an error message (constant
logical “1”). The pull-down current of the clock generator must not exceed 30mA
because the safety switch can no longer handle this current. An error message is then
no longer possible.

3.7 Manipulation prevention
WARNING
The inductive safety switches respond to metallic objects, e.g, the frame of a safety
door. Other metallic objects that are not intended to trigger the safety function must
not be placed near the sensing face of the safety switches under any circumstances.
Appropriate measures must therefore be taken to prevent this.
The safety switch is protected against simple circumvention by the following switching
behavior:
•When slowly bringing a metallic object into the enable zone, the output is triggered
immediately, but is only indicated by the signal LED after a time delay of approx.
3s. As a result, the object is usually in the close range zone before the signal
LED lights up. The technical regulations relating to restarting the system must be
observed.
•If this object remains in the close range zone for longer than approx. 2s, the
output is completely blocked and is no longer enable if actuation occurs in the
enable zone. If the object remains in the close range zone for longer than approx.
5s, adjustment mode is activated see "Adjustment", page 21.
The enable zone can be unlocked either
•by de-actuation (>30mm) for a period of more than 2s
or
•by interrupting the voltage see "Adjustment", page 21.

4 Mounting
WARNING
The safety system must only be mounted by authorized qualified personnel.
Select the mounting location and the mounting position of the safety switch in such a
way that
•the safety switch is difficult to access for operating personnel when the protective
device is open,
•thorough checking and replacement of the safety switch is possible.
WARNING
Circumvention of the inductive safety switch in a simple way or unintentional
actuation must be prevented by suitable installation measures in accordance with
ENISO14119.
DANGER
Damage to the safety switch due to mechanical stress
Loss of the safety function
bProtect the safety switch from mechanical stress such as impacts or permanent
contact pressure, for example by means of an additional stop.
4.1 Mounting the IN40-D0101K safety switch
WARNING
The IN40-D0101K safety switch must not be flush mounted in steel.
•The IN40-D0101K safety switch can be installed flush or non-flush in copper,
aluminum and brass; this results in the classification I1C40SP2 according to EN
60947-5-2.
•The IN40-D0101K safety switch must not be installed flush in steel; this results in
classification I2C40SP2 according to EN 60947--5-2.
•Note the assured switch-off distance and enable zone (see figure 1, page 10).
•The minimum distances for adjacent and opposite sensors, and the minimum
distances to fixed system components and walls shown in the following figure
must be maintained.

Angles Channel
•The IN40-D0101K safety switch must be mounted so that the sensing face of the
sensor is oriented towards the moving part of the protective device (door or the
like). The sensing face can be aligned if necessary.
The safety switch is supplied pre-mounted on a mounting bracket. The mounting
bracket does not need to removed to align the sensing face of the sensor.
Align the sensing face of the safety switch so that it is oriented towards the moving part
of the protective device (door or the like) after mounting; do the following if necessary
•unscrew the hexagon socket screw on the sensor bracket and pull the sensor off
the bracket (see figure 4 a-b),
•loosen the two screws at the lower corner of the sensor housing and rotate the
active sensor face into the correct position (see figure 4 c-d),
•screw the sensor housing back on and remount the sensor on the sensor bracket
(see figure 4 e-f).

WARNING
The IN40-D0303K and IN40-D0202K
safety switches must not be mounted flush.
•The IN40-D0303K safety switch must not be installed flush; this results in classifi‐
cation I2A18SP2M according to EN 60947-5-2.
•The IN40-D0202K safety switch must not be installed flush; this results in classifi‐
cation I2A30SP2M according to EN 60947-5-2.
•The IN40-D0304K safety switch can be installed flush; this results in classification
I1A18SP2M according to EN 60947-5-2.
•Note the assured switch-off distance and enable zone (see table 2, table 3 respec‐
tively table 4).
•The minimum distances for adjacent and opposite sensors, and the minimum
distances to fixed system components and walls shown in the following figures
must be maintained.

5 Connection and adjustment
5.1 Electrical connection
The supply voltage (L+...L-) must be connected between pin 1 and pin 3 of the male
connector. The nominal voltage is 24VDC. This voltage is allowed to fluctuate between
19.2V and 30V with a residual ripple of 5% in accordance with EN 61131--2.
WARNING
The supply voltage must comply with SELV according to EN 60950--1.
To deploy and use the device in accordance with cULus requirements, the supply
voltage must be provided by a secondary fuse-protected transformer. A safe industrial
power supply unit with overvoltage protection must be used. In the event of an error,
60VDC must not be exceeded.
For cuboid sensors, the following applies:
overcurrent protection
Cable diameter for control current circuit Maximum load on the protective device
AWG (mm²) Ampere
26 (0.13) 1
24 (0.20) 2
22 (0.32) 3
20 (0.52) 5
18 (0.82) 7
16 (1.3) 10
For cylindrical sensors, one of the following requirements must be met:
•max. 5A for voltages from 0 ... 20Vrms (0 ... 28.3Vp)
•100/Vp for voltages from 20 ... 30Vrms (28.3 ... 42.4Vp)
