Compact Non-Contact Door Switch/Non-Contact Door Switch Controller
D40A/G9SX-NS
Electronic Detection Mechanism for
Better Stability in Non-contact Door
Switch Operation
Connection is also possible to a G9SP Safety Controller.
Complies with ISO 13849-1(PLd/Safety Category 3).
The maximum number of Switches that can be connected to a
G9SPseries Controller is given below.
G9SP-N10S: 15 1 system
G9SP-N10D/20S: 15 2 system
For details, refer to the G9SP Series Operation Manual (Cat. No.Z922).
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.
Be sure to read the Safety Precautions on page 28 and

Issue 2
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.
