D40A Compact Non-Contact Door Switch

G9SX-NS Flexible Safety Unit

Electronic Detection Mechanism for Better Stability in Non-contact Door Switch Operation

• Stable operation reduces Controller errors caused by unstable doors.

• Connect up to 30 Non-contact Door Switches with LED indicators to one Controller.

• Reversible switch provides flexibility in installation.

• Two-color LED indicator enables easier maintenance by identification of door status and cable disconnections.

• Safety category 3 (EN 954-1).

• Both Non-contact Door Switches and conventional Key-type Safety-door Switches can be input to one Controller, saving space.

• OFF-delay output provided for stop category 1.

• Easily construct partial stop and complete stop systems with the logical AND connection function, using G9SX as the Controller.

D40A Features

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

Mount from Either Side

Connect Up to 30 Switches to a Single Controller

G9SX-NS Features

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.

Two Different Controllers

Indicators That Make Maintenance Easier

Mechanical Safety Door Switches Can Also Be Connected with the G9SX-NSA

Expansion Units to Easily Increase the Number of Outputs with the G9SX-NSA

Configuration Examples

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.

Small Assembly System

● Both robots will stop when the emergency stop switch is pressed.
● Robot A will stop when robot door A is opened.
● Robot B will stop when robot door B is opened.

Semiconductor Inspection System

● The entire system will stop if the emergency stop switch is pressed.
● Only segment A will stop if door A (with door switch) is opened.
● Only segment B will stop if door B (with door switch) is opened.
● Only segment C will stop if the door with the D40A is opened.
