GlobalOMRON's unique electromagnetic induction system for safety was achieved by implementing a detection function for external wiring errors in the Switch.
D40Z
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
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.
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
Safety software monitoring and diagnosis to detect failures
(not possible with series connections of mechanical switches)

Series connections of the D40Z
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.
Centralized monitoring
The auxiliary output supports bipolar NPN/PNP, allowing for easy connection with any PLC.
The error location can be easily identified.
Using a branch relay for a different pole is not required.
