GKMA36
Product Description
When the application requires a miniature key-operated safety interlocking limit switch for machine guarding, Honeywell provides the GKM Series. The compact housing size of 34 mm L x 16 mm W x 70 mm H is optimal where there is limited space available on machinery. The double-insulated plastic housing and rugged stainless steel actuator key are better suited for demanding environments. The unique design of the switch allows the actuator key to be inserted from the top or the side. The switch can be mounted from the front or back as required. As with the Honeywell safety limit switches, 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, opening the circuit. The switches are available with either a cable connection or an integral four-pin M12 connector.
