Why Choose the ABB MKey Key 2 Standard Safety Interlock Actuator?
The ABB MKey Key 2 2TLA050040R0202 is a standard stainless steel actuator key for MKey safety interlock switches with metal heads. Part of the ABB Jokab Safety MKey accessory range, it provides the mechanical actuator required for dependable guard position monitoring on industrial machinery fitted with compatible MKey safety switches.
Manufactured from durable 316 stainless steel, the MKey Key 2 is designed to withstand repeated operation in demanding industrial environments. The actuator is mounted to a movable machine guard, door or hatch and enters the corresponding MKey switch head when the guard closes, allowing the safety interlock mechanism to operate.
The 2TLA050040R0202 is compatible with MKey models using the appropriate metal head, including MKey5 SSH, MKey5+ SSH, MKey5Z, MKey5+Z, MKey8 and MKey9 variants. Its standard straight-key format is particularly suitable for conventional hinged and sliding guard arrangements where accurate switch-to-actuator alignment can be maintained.

Reliable Actuation for Metal-Head MKey Safety Switches
Tongue-operated safety interlock systems use an actuator mounted to the movable guard and a safety switch mounted to the fixed machine structure. When the guard closes, the ABB MKey Key 2 enters the metal switch head and operates the interlock mechanism. Opening the guard withdraws the key, allowing the safety system to detect the change in guard position and initiate the appropriate machine safety response.
The MKey Key 2 provides a simple and durable mechanical interface between a machine guard and compatible ABB MKey safety switches. Its 316 stainless steel construction supports reliable repeated operation, while the standard key profile is ideal for applications where the guard and switch can be installed with consistent mechanical alignment.
Typical Applications
- Industrial machine safety doors and guards.
- Safety gates and access hatches.
- Packaging and production machinery.
- Conveyor and material handling systems.
- Automated manufacturing equipment.
