D4BS's exclusive-use Operation Key is provided
to assure accurate switching operation.
A triangular Set Zone Mark makes it
easy to adjust the operating position
when inserting the Operation Key.
A shearing force contact separating mechanism (NC
contact) is employed, which positively pulls apart the
contacts from each other by using shearing force if
any abnormality such as contact welding should occur
in the contact area.
There is a difference in level between the NC and NO
terminal, which assures easy wiring.
A ground terminal is provided to
improve safety. (Built into the
Unit.)
Available in four different types of conduit
threads: Pg 13.5, G1/2, or 1/2-14NPT, M20.
The operation plunger employs an oil seal, with
which the switch box meets the requirements of
IP67 (the sealing capability of the Operation Key's
insertion mouth is IP00).
The switch head is coated with easy-to-see red
paint. The mounting direction of the switch head can
be varied to any of the four directions.
