Why Choose the ABB MKey5 2TLA050003R0100 Safety Interlock Switch?
The ABB MKey5 2TLA050003R0100 is a compact and robust mechanical safety interlock switch designed for position monitoring of movable machine guards, gates and access hatches. As part of the ABB Jokab Safety MKey series, it uses a separate actuator key to detect when a protective guard is correctly closed and can form part of a machine safety control system.
The MKey5 features a durable plastic housing and plastic actuator head with a 2NC + 1NO contact configuration when the actuator is inserted. Its normally closed safety contacts use direct opening action, providing dependable guard position monitoring for industrial machinery. The switch head can be rotated to provide four actuator entry positions, simplifying installation on sliding, hinged and lift-off guards.
With an IP67 protection rating, 12 N actuator holding force and three M20 conduit entries, the MKey5 is well suited to demanding industrial machine safety applications. A standard stainless steel actuator key is supplied with the switch, providing the components required for a conventional guard interlocking installation.
Key Advantages
- Reliable mechanical safety interlock switch for movable machine guards.
- 2NC + 1NO contact configuration with direct opening action on the NC safety contacts.
- 12 N actuator holding force for dependable guard position retention.
- IP67 protection for industrial operating environments.
- Rotatable switch head provides four actuator entry positions for installation flexibility.
- Standard stainless steel actuator key supplied with the interlock switch.
Key Features
- ABB Jokab Safety MKey5 series.
- 2 normally closed + 1 normally open contacts with actuator inserted.
- 12 N holding force.
- Three M20 conduit entries for electrical connections.
- Plastic housing and plastic actuator head.

- Standard actuator key manufactured from stainless steel.
- Mechanical life of approximately 1 million switching operations.
Reliable Guard Monitoring for Industrial Machinery
Mechanical safety interlock switches monitor the position of movable guards and help prevent machinery from operating unless the protective guard is correctly positioned. The ABB MKey5 is installed on the fixed machine frame while its separate actuator key is attached to the moving guard. When the guard closes, the actuator enters the switch head and changes the state of the safety contacts.
The MKey5 is designed for sliding, hinged and lift-off guards used on industrial machinery. Its direct-opening normally closed contacts, configurable actuator entry positions and compatibility with high-performance safety architectures make it a versatile solution for integrating mechanical guard monitoring into modern machine safety systems.
Typical Applications
- Industrial machine guard doors and access gates.
- Sliding, hinged and lift-off protective guards.
- Robot cell and automated equipment enclosures.
- Packaging and production machinery.
- Conveyor and material handling safety systems.
- OEM machine-building and factory automation installations.
