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.

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.

Note: 1.
If a 100/230 VAC power supply is used, connect it to the A1
and A2 terminals. Do not connect the power supply to the +
and

2.
If a 24 VDC power supply is used, connect it to the + and

!WARNING
Do not connect a 100/230 VAC power supply to the +
