Compact non-contact Door Switch


Supports ISO 13849-1 (PLe/Safety Category 4). Can be used on higher risk level applications by connecting to Safety Controllers.

High level of safety for a wide range of applications

ISO 13849-1 (PLe/Safety Category 4) achieved with Non-contact Door Switches

Self-diagnostic Function

OMRON's unique electromagnetic induction system for safety was achieved by implementing a detection function for external wiring errors in the Switch.

Redundant internal circuits

The thorough pursuit of safety is evident in mutual checking by double CPUs.

Series connections

Up 30 Switches can be connected to one Controller while maintaining PLe/safety category 4.

The D40Z can be connected to G9SP or G9SX-NS[] Safety Controllers. Select the best model for your application.

D40Z Features 7

Note 1: The G9SP supports 2 channels of 15 units each. For more information, refer to Applicable level and the number
            of connections according to controller combination on Catalog.
Note 2: Refer to Catalog for details on safety categories (ISO 13849-1).

How PLe/safety category 4 was achieved with series connections

D40Z Features 11

Electromagnetic induction method

Enables stable detection

With these electronic switches, stable detection is possible even when the door closes slowly.

No adhesion of iron particles

Permanent magnets are not used, so iron is not attracted, making maintenance easier.

Visible safety

Checking at the production site

The switch's LED indication patterns make identification of abnormal condition possible at the production sites.
Note: For more information, refer to Catalog.

D40Z Features 16

Centralized monitoring

Bipolar NPN/PNP allows for easy connection with any PLC.
The error location can be easily identified. Using a branch relay for a different pole is not required.
