Why Choose the ABB MKey8M 24VDC Safety Interlock Switch?
The ABB MKey8M 24VDC, part number 2TLA050013R0132, is a heavy-duty mechanical safety interlock switch with electromagnetic guard locking designed for monitoring and retaining doors, hatches and movable guards on industrial machinery. Its robust die-cast housing and head, 24 V DC power-to-lock solenoid and 2000 N holding force make it particularly suitable for applications where a guard must remain closed during a production process.
As part of the ABB Jokab Safety MKey series, the MKey8M combines mechanical actuator monitoring with a magnetic process-locking function. The actuator key is mounted on the movable guard and enters the switch head when the guard closes, while energising the solenoid engages the locking mechanism. The switch incorporates positively operated safety contacts for monitoring the actuator and lock condition.
The 2TLA050013R0132 features a 24 V DC control supply, IP67 enclosure protection, three M20 conduit entries and a standard actuator key. With dimensions of approximately 176 × 46 × 47 mm, the MKey8M provides a compact but high-strength guard-locking solution for industrial automation and machine safety installations.

Heavy-Duty Guard Locking for Industrial Machinery
Guard-locking interlock switches are used where detecting a closed guard alone is not sufficient and the guard must also be retained during part of the machine operating cycle. The ABB MKey8M uses a 24 V DC electromagnetic power-to-lock mechanism, providing a substantial 2000 N holding force when the locking solenoid is energised.
The MKey8M is intended as a process lock and combines actuator position monitoring with monitoring of the locking mechanism. Its rugged die-cast construction and IP67 protection make it suitable for machinery, automated cells, conveyors and production systems where dependable mechanical guard retention and position monitoring are required.
Typical Applications
- Machine guard doors requiring process locking.
- Automated production and assembly machinery.
- Robot cell access doors and perimeter guarding.
- Conveyor and material handling equipment.
- Packaging and processing machinery.
- OEM machinery and industrial automation systems.
