Cover
The cover, with a hinge on its lower part, can be
opened by removing the screw of the cover, which
ensures ease of maintenance and wiring.
Note: The housing and head of the D4NH are made of resin. Use D4BS
The built-in switch has a direct opening mechanism
that forcibly separates the NC contact even when
there is contact deposit.

Safety-door Switches for applications requiring safety door switches of tough,
high-sealing, or oil-resistant construction.
When the guard is opened, the cam that is directly coupled to
the shaft rotates to press the Switch in the direction shown by
the (vertical) arrow. This action separates the contacts to stop
the machine.

Arm Lever
The joint between the shaft and
arm lever is formed with
form-lock construction which
remains secure even when the
screw becomes loose.
Conduit
A wide variety of conduits is available.
The arm lever is mounted upwards in the center
position before shipping. To change the position,
loosen the arm lever mounting screw, dismount
the arm lever, and mount the arm lever in the left
or right position.
