ABB 2TLA050009R2012 Guard Locking Safety Switch

ABB 2TLA050009R2012 MKey9M Guard Locking Plastic Safety Switch is a 24 VDC guard-locking interlock that provides power-to-lock operation to secure machine guarding doors, delivering up to 1800 N of holding force to keep a guard closed during operation. The unit features a plastic housing designed for compact installation within control panels and is part of ABB Jokab Safety’s MKey9M family of guard-locking switches. The solenoid operates at 24 V DC with a nominal coil power of 12 W (inrush 50 W), and the design supports a 10 mm travel for positive opening, aligning with the series’ standard operating characteristics. Typical applications include safeguarding access doors on automated production lines, robotic work cells, conveyors, and presses, where reliable locking until the area is safe is essential for preventing access to hazards. With its 1800 N holding force and 24 VDC operation, this interlock helps ensure safe restart after the protective device is released and hazards have been addressed.
