Features
● Easy-to-see 2-Color Indicators
● Mount from Either Side
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
Swinging doors
● Small Actuator
Sliding doors
● Save Labor with Connector and Reduce Inventory
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.
Compact
Switch
Mount from whichever side provides the
easiest wiring path to enable mounting to all
types of doors.
Wiring time can be reduced with the connector.
Cable lengths can be selected, and only cables of
required lengths can be purchased.
Switches can be integrated into a single Switch
with a connector when installing in a machine with
multiple doors or various types of machines,
which can reduce inventory.

D40A/G9SX-NS
Solves Conventional Switch Issues to Provide Stable Detection
Issue 1
The Switch does not accurately detect the door when it is closed slowly, resulting in an error.
Conventional switch
An error can occur
if the door is closed
slowly with
conventional
switches.

Issue 2
If the switching timing of reed
switch contacts 1 and 2 varies
too much, the Controller
detects an error and turns OFF
the output to maintain safety.
Stable Detection

New System
Note: The figure is intended
only as an illustration.
Detects slow lateral operation.
Detects slow rotating operation.
It is nearly impossible to tell which door is open in a multi-door application.
If an error occurs...
The system cannot be started because the Controller has turned
OFF the output even though all doors appear to be closed.
It's impossible to tell if there is a door open or if an error has occurred.
All doors must be opened and closed before operation can be started.
Solution 2
With the D40A...
The auxiliary outputs can be used to easily indicate which door is
open.
And with two-color indicators, mounting adjustments are also easy.
The D40A is the first Non-contact Door Switch to combine 2-color
indicators, auxiliary outputs, and 30-switch connection capacity,
allowing you to create a better safety environment.
Issue 3
Various cable lengths and complex wiring are required for multiple doors.
Solution 3
The model with a connector allows you to select the cable lengths that are connected and purchase the
cables of required lengths. Switches can be integrated into a single Switch with a connector.
Downtime can be reduced by replacing the cable and switch partially at maintenance time.

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 Non-contact door switch, 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.
● Two Different Controllers

“b”, which is input to Unit B.
Thereby the logic of the safety output of Unit B is
(AND). (An AND of inputs “a” and “b” is output.)
To set the safety outputs of the subsequent Unit in the

• 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.)

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.

Setting Procedure
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.

3. Setting Logical 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.

21. Wiring
1. G9SX-NS@-RT (with Screw Terminals)
• Use the following to wire the G9SX-NS@-RT.
Solid wire
(steel wire)
0.2 to 2.5 mm2 (AWG24 to
AWG12)
Stranded wire
(flexible wire)
0.2 to 2.5 mm2 (AWG24 to
AWG12)
• Tighten each screw to the specified torque of 0.5 to 0.6 N·m,
or the G9SX-NS@ may malfunction or generate heat.
• Strip the wire for no longer than 7 mm.
2. G9SX-NS@-RC (with Spring-cage Terminals)
• Use the following to wire the G9SX-NS@-RC.
Solid wire
(steel wire)
0.2 to 2.5 mm2 (AWG24 to
AWG12)
Stranded wire
(flexible wire)
0.2 to 2.5 mm2 (AWG24 to
AWG12)
• Strip the wire for no longer than 7 mm.
3. Logical AND Connections
• Use VCTF cables or shielded cables for logical AND connect
ions between Units.
22. Connecting G9SX-EX@-@ Expansion Units
1. Remove the terminating connector from the connector on the
G9SX-NSA222-T03@. Insert the connector on the connecting
cable of Expansion Unit into the connector on the G9SX-NSA222T03-@.
2. Connect the terminating connector to the connector on the
Expansion Unit at the end position.
When the G9SX-NSA222-T03-@ is used without Expansion
Units, leave the terminating connector on the G9SX-NSA222T03-@.
3. Do not remove the terminating connector or connecting cables
of Expansion Units while the system is operating.
4. Before applying the supply voltage, confirm that the connectors
are locked firmly.
5. All of the Expansion Units must be supplied with its specified
voltages within 10 s after the connected G9SX-NSA222-T03-@
is supplied with voltage.
Otherwise, the G9SX-NSA222-T03-@ will detect a power
supply error for the Expansion Units.
23. Use cables with a length of less than 100 m total to connect the
safety inputs, feedback/reset inputs, and logical AND connection
inputs and outputs.

D40A/G9SX-NS
24. Set the time duration of OFF-delay to an appropriate value that
does not cause the loss of safety functions of system.
25. Logical AND connections between Units (Refer to “Functions” on
page 19.)
1. To use logical AND connection inputs, enable the logical AND
connection input for the G9SX-NS@ that will receive the inputs.
2. Connect the logical AND connection inputs appropriately to the
logical AND connection outputs of the G9SX-@.
3. When configuring the safety system, be sure to consider that
the delay of response time caused by logical AND connection
does not degrade the safety functions of the system. (Refer to
“Response Time and Operating Time” on page 12.)
26. To determine safety distance to hazards, take into account the
delay of safety outputs caused by the following time:
1. Response time of safety inputs
2. Response time of D40A Non-contact Door Switch inputs
3. Response time of logical AND connection input
(Refer to “Response Time and Operating Time” on page 12.)
4. Preset OFF-delay time
5. Accuracy of OFF-delay time
27. Start the rest of the system after 5 s or longer has passed since
applying supply voltage to all G9SX-@ in the system.
28. Be sure to ground the A2 terminal of the power supply to help
prevent malfunctions caused by noise. Also, connect a surge
absorber to each end of the coil on inductive loads to reduce noise
generation. When sharing a power supply with a Light Curtain,
use a DC power supply that will not fail for a momentary power
interruption of 20 ms or less.
29. Devices connected to the G9SX-NS may operate unexpectedly.
When replacing the G9SX-NS, disconnect it from power supply.
30. Adhesion of solvent
Do not allow organic solvents, such as alcohol, thinner,
trichloroethane, or gasoline, to come into contact with the product.
Such solvents make the markings on G9SX-NS illegible and
cause deterioration of parts.
31. Do not mix AC and DC circuits for contact outputs in a single
G9SX-EX@-@. When using AC and DC circuits, connect at least
two G9SX-EX@-@ Units and use them respectively as dedicated
DC-circuit and AC-circuit contact outputs.
32. Safety Application Controller’s Relay durability depends greatly
on the switching condition. Confirm the actual conditions of
operation in which the Relay will be used in order to make sure the
permissible number of switching operations.
When the accumulated number of operation exceeds its
permissible range, it can cause failure of reset of safety control
circuit. In such case, please replace the Relay or the Safety
Application Controller immediately.
If the Relay or the Safety Application Controller is used
continuously without replacing, then it can lead to loss of safety
function.
33. Operate the reset input more than 0.4 seconds immediately after
the safety outputs are OFF.
G9SX does not accept the reset input from when the outputs are
turned ON and until 0.4 seconds passes after the outputs are
turned OFF.
