D40B Series Compact Non-contact Door Switch

Detects the Open/Closed State of Doors Without Making Contact and Has High Resistance to the Environment

• Detects the open/closed state of doors without making contact by combining a special magnetic Actuator and Switch. The switching mechanism is not easily disabled.

• The non-contact operation prevents the creation of particles due to abrasion.

• The Actuator and Switch can be washed with water (not immersible in water). There are no key-holes where dirt can accumulate, making it easy to keep machinery clean.

• Small distortions in the door and mechanical discrepancies can be absorbed in the allowable operating range of the magnetic Actuator and Switch.

• Safety Category 3 (EN954-1).

Features

Special Actuators and Control Unit to Prevent False Operation
