Why Choose the ABB MKey Key 1 Standard Safety Interlock Actuator?
The ABB MKey Key 1 2TLA050040R0201 is a standard stainless steel actuator key for MKey safety interlock switches, designed specifically for compatible MKey switches with a plastic head. As part of the ABB Jokab Safety MKey accessory range, it provides the mechanical actuator required for reliable guard position detection on industrial machinery.
Manufactured from 316 stainless steel, the MKey Key 1 provides excellent mechanical durability and corrosion resistance for industrial installations. The actuator is designed to enter the operating head of a compatible MKey switch when a machine guard or door is closed, enabling the interlock contacts to assume their intended operating state.
The 2TLA050040R0201 is intended for ABB MKey5 and MKey5+ safety switches with plastic heads. Its standard straight actuator format makes it particularly suitable for conventional hinged or sliding guards where the actuator and switch can be accurately aligned.

Reliable Actuation for MKey Safety Interlock Switches
A tongue-operated safety interlock system uses an actuator mounted to the movable machine guard and an interlock switch mounted to the fixed structure. When the guard closes, the ABB MKey Key 1 enters the switch head and operates the interlock mechanism. Opening the guard withdraws the actuator, allowing the connected safety system to detect the change in guard position.
The standard actuator format is suitable where the switch and actuator can be installed with consistent alignment. Its 316 stainless steel construction provides a durable interface between the movable guard and compatible ABB MKey5 or MKey5+ safety switch, supporting dependable operation throughout repeated machine access cycles.
