Omron D40B DATASHEET
Compact Non-contact Door Switch
D40B
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 in water. There are no keyholes 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.
• Conforms to Category 3.

Sensor
Note: 1. These values represent the distances at which OFF changes to ON (approaching) or ON changes to OFF (separating) when the switch
and actuator's target marks are aligned and the sensing surfaces have the same orientation.
2. If the approach speed is less than the specified value, the Controller's safety contact output may not turn ON, even if the distance is less
than the switching distance.
