NEW
D40A/G9SX-NS
Compact Non-Contact Door Switch/
Flexible Safety Unit
Stable Operation Increases Line Efficiency

New Type of Non-Contact Door Switches for
Worker Safety and Higher Productivity
These new Non-Contact Door Switches provide more stability in detection than
previously possible with non-contact door switches.
●Easy-to-see 2-Color Indicators
●Small Actuator
Solves Conventional Switch Issues to Provide Stable Detection
The Switch does not accurately detect the door when it is closed slowly, resulting in an error.
The D40A does not use reed switches and
provides stable detection with electronic switches.
Conventional Switches
Detects slow rotating operation.
Compact
Switch status is easy to see at a glance with
these red/yellow LED indicators.
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.

Mount from whichever side provides the easiest wiring
path to enable mounting to all types of doors.
Reduce costs by connecting up to 30 Switches to a single Controller.
It is nearly impossible to tell which door is open in a multi-door application.

If an error occurs...
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.
It's impossible to tell if there is a door open or if an error has occurred.
The system cannot be started because the Controller has turned
OFF the output even though all doors appear to be closed.
All doors must be opened and closed before operation can be
started.

Two Types of Controller to Solve Productivity,
Expandability, and Maintenance Issues
●Two Different Controllers
Reduce Costs with these New-Concept Controllers
Two Controllers are required for emergency stop switches and
non-contact door switches.
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.

are detected.
Auxiliary outputs for errors also
contribute to reducing down

Logical AND Connections
OMRON's unique logical AND connections enable easily constructing safety circuits that were troublesome with
previous Controllers. The new Non-contact Door Switch Controllers embody the concepts for the G9SX Series, so you
can also use the previous G9SX-series Controllers in the same system.
