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 abra-
sion.
• The actuator and switch can be
washed in water. There are no key-
holes where dirt can accumulate, mak-
ing it easy to keep machinery clean.
• Small distortions in the door and me-
chanical discrepancies can be ab-
sorbed in the allowable operating range
of the magnetic actuator and switch.
• Conforms to Category 3.
