MICRO SWITCH Key Actuated Safety Switches 004738 GKE Series Issue 2 Datasheet FEATURES Red switch body for easy safety recognition 20 mm to 22 mm mounting centers per EN50047 which accept M4 or 8 mounting hardware Different contact options 1NC (normally closed) and 1NO (normally open) or 2NC All NC contacts are positive opening to EN/IEC 60947-5-1-3 specification Actuator head can be indexed in any of four positions, in 90 increments Switch chamber sealed to IP66/IP67 and NEMA 1, 4X (indoor), 12, 13 CE, CCC, and cULus certifications for global applications Different threaded conduit options DESCRIPTION Designed and agency evaluated, per SIRA, for safety The Honeywell GKE Series key-operated safety interlocking functions up to and including a SIL3 level limit switches are designed for machine guarding applications. The switches mount on the EN50047 mounting pattern of POTENTIAL APPLICATIONS the 20 mm to 22mm mounting centers. The compact size Safety interlock for guards or doors on equipment and is preferred where there is limited space on machinery. The machinery double-insulated plastic housing and rugged stainless steel Designed for hinge or sliding guards or doors actuator key is a logical choice for demanding environments. The design of the switch allows the actuator key to be inserted DIFFERENTIATION from the top or side of the switch. As with the Honeywell Switch design with dual entry (side or top) for actuator key safety limit switches, all normally closed contacts are positive Compact size of 31 mm L x 33 mm W x 96 mm H 1.2 in L x opening . 1.3 in W x 3.8 in H Rigid or flexible stainless steel actuator keys PORTFOLIO In addition to the GKE Series safety interlocking limit switches, Honeywell offers other safety interlocking limit switches. These include the miniature plastic body GKM Series, the compact 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 metal body GSS Series, metal and plastic body non-contact FF Series, metal body 1CPS Series and 2CPS Series cable/rope pull safety limit switches.
