Auto Switch Specifications

 It is possible to use in an en-

vironment which generates a 
magnetic field disturbance 
(AC magnetic field).

The proper operating range 
can be determined by the col-
or of the light.

Precautions

Caution

For single-phase AC welding machines
If it is used for current inverter welders (in-
cluding rectifying type) and condenser type 
welders, the magnetic field resistance is 
reduced. Please contact SMC regarding 
the performance.

Dimensions

If the current of the AC welding machine is 16000 A or lower, the auto switch can be used, even if the 
distance between the welding conductor (gun cable) and the cylinder/actuator or auto switch is 0 mm.
Please contact SMC when the AC welding current exceeds 16000 A.

  When the auto switch is ordered on its own, the auto switch mounting bracket is not enclosed. 

In that case, please order it separately.  

Note) A white color heat 

shrink tube is attached 
to the D-P3DWSE 
type only.
