ABB 2TLA050007R1112 Industrial Safety Switches

ABB Jokab Safety 2TLA050007R1112 is a solenoid-locking guard safety interlock switch from the MKEY9 family, designed to secure guarded access on industrial machinery and prevent operation when a guard is open. It operates from a 24 V DC coil drawing 12 W and provides a 2NO-2NC contact configuration for both interlock function and status signaling, compatible with safety controllers that monitor door position. The device features manual action with a standard key actuator, an IP67-rated enclosure with NPT connection and threaded mounting, and dimensions of roughly 6.3 x 1.81 x 1.79 inches, with a temperature range of -25 to 55 C; enclosure material is reported as polyester in ABB Jokab Safety documentation, though some retailers list plastic variants. Listed operating cycles are 8 cycles per hour, and this part is commonly used on guarded safety gates in automated lines to ensure the door remains locked until the safety circuit confirms safe conditions.
