MICRO SWITCH Key Actuated Safety Switches GKM Series 004750 Issue 5 Datasheet FEATURES • Red switch body for easy safety recognition • Common 22 mm mounting centers which accept M4 or #8 mounting hardware • Prewired cable or M12 connector for electrical termination • Positive opening action of normally closed contacts to EN/IEC 60947-5-1-3 specification • Switch chamber IP67 environmentally sealed for indoor or outdoor applications • CE and UL certifications • Designed and agency evaluated for safety functions up to and including a SIL3 level 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. Sensing and Internet of Things POTENTIAL APPLICATIONS • Safety interlock for small doors and apertures on machinery • Safety interlock for multiple doors on machinery with daisy chain option (twin connectors) DIFFERENTIATION • Miniature package size of 34 mm L x 16 mm W x 70 mm H • Switch design with dual entry (side or top) for actuator key • Daisy-chain capability for monitoring multiple gates on machinery • Rigid or flexible stainless steel actuator keys PORTFOLIO In addition to the GKM Series safety interlocking limit switches, Honeywell offers other safety interlocking limit switches. These include the EN50047 plastic body GKE Series, plastic body GKN Series, EN50041 metal body GKB Series, and metal body solenoid (trapped key) GKL/R Series. Non-interlocking safety limit switches include the GSS Series, FF Series non-contact switches, and the 1CPS Series and 2CPS Series cable/rope pull safety limit switches. Key-Actuated Safety Switches, GKM Series Table 1.
