Magnetic field resistant

auto switch

Miniaturization of the auto switch has made it possible to mount onto cylinders/
actuators with small bore sizes (

ø25

and

ø32

Can be mouned on

bore size

cylinder/actuator.

AC spot welders

For use with

AC spot welders

which generate strong
magnetic field.

It is possible to use in an environment which generates
a magnetic field disturbance

(AC magnetic field)

It is possible to use in an environment which generates
a magnetic field disturbance

(AC magnetic field)

If the current of the AC welding machine
is 16000 A or lower,

the switch can be used,

even if the distance between the welding
conductor and the cylinder/actuator or

auto switch is

RoHS

compliant
