Omron Scientific Technologies, Inc. introduced D40A non-contact door switches. Features include high-visibility, two-color LED indicators that provide "at a glance" status indication at the guard door for quick adjustments, as necessary.
An auxiliary contact also allows for remote status indication. The D40A switch can be mounted to accept the actuator on the left or right side without having to change the location of the cable.
The D40A controller may be used to monitor D40A non-contact switches, and tongue or key actuated switches, and allows users to connect up to 30 D40A switches to a single controller.
It may also be used as a stand-alone safety controller, or for more complex applications it may be used as a component in the G9SX modular relay system. When used part of the G9SX relay system, users can benefit from delayed stops and logical AND functions.
