GK Series

Heavy duty construction for harsh industrial environments

Designed with a wide key entry tolerance, to accommodate drift in door alignment over the life of the machine,

Compliance with the relevant European directives is assured with this design. Each switch is available with either a straight or a 90° key.

Contact blocks have screw terminals enabling use of spade wiring terminals, complying with global safety requirements.

Galvanically isolated contacts permit wiring normally closed and normally open contacts to different loads and polarities.

Forced disconnect mechanism on normally closed contacts conforms to IEC 947-5-1.

Resistance to tampering

Built-in compensation for key misalignment

IP67, NEMA 4 sealed enclosure - withstands high pressure washdown

Typical applications include hinged and sliding guard doors, protective covers and enclosures on machine tools, packaging machinery, conveyors, elevators, cranes, hoists and lifts and construction machinery equipment
