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.

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.

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.
