The ABB MKey5 SSH, part number 2TLA050003R0110, is a robust mechanical safety interlock switch designed for monitoring doors, hatches and movable guards on industrial machinery. It combines a durable plastic/polyester body with a stainless steel head, a 12 N holding force and a 2NC + 1NO contact configuration with the actuator inserted.
As part of the ABB Jokab Safety MKey series, the MKey5 SSH operates using a separate actuator key mounted on the moving part of the machine guard while the switch body is installed on the fixed frame. When the guard opens, withdrawal of the actuator mechanically changes the safety contacts, allowing the associated machine safety control system to detect the open guard condition.
The 2TLA050003R0110 offers IP67 enclosure protection, three M20 conduit entries and is supplied with a standard actuator key. Its stainless steel head provides additional durability at the actuator interface, making this MKey variant particularly suitable for industrial guarding applications requiring a robust mechanical interlock.
Mechanical safety interlock switches such as the ABB MKey5 SSH are used to monitor movable machine guards and access points. The switch is mounted on the fixed part of the guarding structure and its actuator key on the moving guard, so opening the guard withdraws the actuator and positively operates the safety contacts for detection by the machine safety control system.
The MKey5 SSH combines direct-opening NC contacts with a rugged IP67 enclosure and a durable stainless steel head. These features make it well suited to machine builders and industrial automation engineers requiring dependable mechanical guard monitoring on production machinery, conveyors, automated cells and other guarded equipment.
