The Limit Switch with Better Seal, Shock 
Resistance, and Strength

• A double seal on the head, a complete gasket cover, and other 

features ensure a better seal (meets UL NEMA 3, 4, 4X, 6P, 12, 
13).

• Block mounting method to reduce weight to 290 g.

• Block mounting method also reduces downtime for mainte-

nance.

• Wide standard operating temperature range: 

–40

°

C to 100

°

C (standard type).

• Models with fluoro-rubber available for greater resistance to 

chemicals.

• DPDT, double-break models available for complex operations.
