MICRO SWITCH Solenoid Safety Interlock Switches 004789 GKL/R Series Issue 2 Datasheet FEATURES Electrostatic epoxy coated die-cast zinc housing Four different rugged stainless steel keys (two rigid and two flexible) 1NC/1NO, 2NC, 2NC/1NO, 2NC/2NO, 3NC/1NO, or 4NC contact options each for monitoring the key and the solenoid Positive opening normally closed contacts to EN/IEC 60947-5-1-3 specification Mechanical latch (solenoid power to unlock) or solenoid latch (de-energize solenoid to unlock) Manual unlock feature on front cover Two LEDs in housing cover for monitoring the actuator key switch contacts and the solenoid switch contacts Different conduit options for global applications DESCRIPTION Operating temp. range: -25 C to 85 C -13 F to 185 F MICRO SWITCH GKL/R Series switches are a heavy-duty key Switch body environmentally sealed to IP68 and operated solenoid safety interlock switch incorporating a key NEMA 1, 4, 6P, 12, & 13 trapping mechanism. The trapped key attached to the guard CE, CSA, and UL agency certifications cannot be removed from the switch until the solenoid circuit of Designed and agency evaluated for safety functions up to the switch has received a remote signal (from a control device) and including a SIL3 level indicating the hazardous process has subsided. This design is for use on machinery where an instant stop is either impossible POTENTIAL APPLICATIONS (due to the momentum of the machine) or impractical due to Potential applications include gates, guards, and doors for: machine conditions (such as completing a machine cycle or - Machine tools reducing the temperature to a safe level). There are independent - Metalworking and punch press machinery contacts inside the key switch which monitor the key position - Plastic molding machines and the solenoid with a range of different contact arrangements - Die cast machinery to satisfy most application requirements. All normally closed - Robotic cells contacts of the switch are positive opening . The key switch - Special purpose machinery also incorporates a manual override feature on the front cover which allows removal of the key for emergency access. DIFFERENTIATION To facilitate installation, the switch is available as a GKL Series Up to four electrically independent contacts for each of the (head to the left) or a GKR Series (head to the right). The GKL/R key and solenoid for monitoring the respective positions Series switches are designed with dual-entry positions (side or Gold contacts available for low energy applications top) for the key. Two LED indicators (green and red) to monitor status of key switch and solenoid switch VALUE TO CUSTOMERS Rugged stainless steel rigid and flexible keys Trapped actuator key cannot be removed from the switch until Designed and evaluated up to and including a safety the hazardous condition has subsided integrity level (SIL3) per IEC 61508-2:2010 Trapped key available as a mechanical latch or solenoid latch Heavy duty metal housing assembly resists shock, vibration, PORTFOLIO and oil/coolant sprays Honeywell safety interlocking switches include the EN50041 Side or top entry positions (8 positions) for key metal body GK Series, miniature plastic GKM Series, EN50047 Multiple positive opening normally closed (NC) contacts and plastic body GKE Series, and plastic body GKN Series. normally open (NO) contacts options Honeywell also offers non-interlocking safety switches (GSS Lockout device available, key cannot be inserted into switch Series), non-contact safety switches (FF Series) and cable/ rope-pull safety switches (1CPS & 2CPS Series).
