Compact Non-Contact Door Switch/Flexible Safety Unit
D40A/G9SX-NS
Electronic Detection Mechanism for
Better Stability in Non-contact Door
Switch Operation
Features
Be sure to read the “Safety Precautions” on page 24 and
the “Precautions for All Safety Door Switches”.
● Easy-to-see 2-Color Indicators
Switch status is easy to see at a glance with
these red/yellow LED indicators.
Red:
Open door
detected.
Yellow:
Closed door
detected.
Not lit:
Power OFF
or failure
● Small Actuator
An actuator that is smaller than the switch
saves space, even inside the door.
Even when mounted with an L-bracket, the
actuator's height will not hinder installation or
operation.
● Connect Up to 30 Switches to a Single Controller
Up to 30 Switches
Reduce costs by connecting up to 30 Switches to a single Controller.

Solves Conventional Switch Issues to Provide Stable Detection
The Switch doesnot accurately detect the door when it isclosed slowly, resulting in an error.
Issue 1
Door
closed
slowly.
An error can occur
if the door isclosed
slowly with
conventional
switches.
Conventional switch
The D40A doesnot use reed switchesand
providesstable detection with electronic switches.
Conventional Switches

Solution 1

Magnet
Reed switch contactsReed switch contacts
Magnet If the switching timing of reed
switch contacts1 and 2 varies
too much, the Controller
detectsan error and turnsOFF
the output to maintain safety.
Note: The figure isintended
only as an illustration.

It isnearly impossible to tell which door isopen in a multi-door application.
Issue 2
If an error occurs...
It'simpossible to tell if there isadoor open or if an error has occurred.
The system cannot be started because the Controller has turned
OFF the output even though all doorsappear to be closed.
All doorsmust be opened and closed before operation can be started.
With the D40A...
Solution 2
The auxiliary outputscan be used to easily indicate which door is
open.
And with two-color indicators, mounting adjustmentsare also easy.
The D40A isthe first Non-contact Door Switch to combine 2-color
indicators, auxiliary outputs, and 30-switch connection capacity,
allowing youto create abetter safety environment.

D40A/G9SX-NS
Two Types of Controller to Solve Productivity, Expandability, and Maintenance Issues
The G9SX-NS and G9SX-NSA are designed specifically for use with the D40A, and with the G9SX-NSA you can also connect mechanical safety
door switches. Among other features, these Controllers support logical AND connections that enable partial stops. These Controllers make the
most of D40A Switches.

Logical AND Connection
A logical AND connection means that the G9SX outputs a safety
signal “a” to another G9SX, and that G9SX creates the logical AND of
safety signal “a” and safety signal “b.” The safety output of the
G9SX-NSA222-T03-@with the logical AND connection shown in the
following diagram is “a” AND “b.”
This is illustrated using the application in the following diagram as an
example. The equipment here has two hazards identified as Robot 1
and Robot 2, and it is equipped with Non-contact Door Switches and
an emergency stop button as safety measures. If the door to Robot 2
is opened, only Robot 2 is stopped (i.e., a partial stop). If the door to
Robot 1 is opened or the emergency stop button is pressed, both
Robot 1 and Robot 2 stop (i.e., a complete stop).
The actual situation using a G9SX for this application is shown in this
example.
Note: The logical AND setting on the G9SX-NS202-@must be set to
AND (enabled).
*A manual reset is required when an emergency stop is used.
ConnectingExpansion Units
•The G9SX-EX and G9SX-EX-T Expansion Units can be connected
to a G9SX-NSA222-T3-@Non-contact Door Switch Controller to
increase the number of safety outputs. (They cannot be connected
to a G9SX-NS202-@.)
•A maximum of five Expansion Units can be connected to one
G9SX-NSA222-T03-@. This may be a combination of G9SX-EX
instantaneous models and G9SX-EX-T OFF-delayed models.
•Remove the terminating connector from the receptacle on
G9SX-NSA222-T03-@and insert the Expansion Unit cable
connector into the receptacle. Insert the terminating connector into
the receptacle on the Expansion Unit at the very end (rightmost).
•When Expansion Units are connected to a Controller, make sure
that power is supplied to every Expansion Unit. (Refer to the
following diagram for actual Expansion Unit connection.)

SettingProcedure
1. Cross Fault Detection (G9SX-NSA222-T03-@)
Set the cross fault detection mode for safety inputs by shorting Y1
to 24 V or leaving it open.
When cross fault detection is set to ON, short-circuit failures are
detected between safety inputs T11-T12 and T21-22. When a
cross fault is detected, the following will occur.
(1) The safety outputs and logical AND outputs lock out.
(2) The LED error indicator is lit.
(3) The error output (auxiliary output) turns ON.
2. Reset Mode (G9SX-NS202-@/NSA222-T03-@)
Set the reset mode using feedback/reset input terminals T31, T32,
and T33.
Auto reset mode is selected when terminal T32 is shorted to 24 V
and manual reset mode is selected when terminal T33 is shorted
to 24 V.
3. SettingLogical AND Connection (G9SX-NS202-@/
NSA222-T03-@)
When connecting two or more Non-contact Door Switch
Controllers by logical AND connection, set the logical AND
connection preset switch on the Controller that is on the input side
(Unit B in the following diagram) to AND. The default setting of the
logical AND connection preset switch is set to OFF.
Note: A setting error will occur and Unit B will lock out if the logical
AND setting switch on the Unit B is set to OFF.
4. Settingthe OFF-delay Time (G9SX-NSA222-T03-@)
The OFF-delay preset time on G9SX-NSA222-T03-@is set from
the OFF-delay time preset switch (1 each on the front and back of
the Unit).
Normal operation will only occur if both switches are identically set.
An error will occur if the switches are not identically set. The default
setting of the OFF-delay time preset switch is set to 0 s.
Refer to the following illustration for details on setting switch positions.
