Description
The GKN Series key-actuated safety interlocking limit switches are designed for applications where machine guarding is required. Up to 3 normally closed contacts are available per switch to meet most control circuit applications. All normally closed contacts are positive opening . Direct mechanical linkage within the switch force the normally closed contacts open when the actuator key is removed from the switch. When the actuator key is re-inserted into the switch, the contacts change state. The double-insulated plastic housing and stainless steel actuator-key are designed for demanding environments with the internal switch enclosure being environmentally sealed. The design of the switch allows 4 actuator-key entry locations for installation flexibility. Three conduits are integral to each switch for convenience of electrical connections.
Specifications:
- Housing material: Epoxy coated die-cast zinc
