Overview

ABB MKey mechanical safety switches (SKU: 2TLA050040R0611) provide reliable door and hatch monitoring for industrial safety applications. These switches are designed for harsh environments, including manufacturing, automation, and access control systems, ensuring personnel and equipment protection while maintaining operational efficiency. The MKey series features a rugged polyester housing and head with IP67 protection, suitable for demanding industrial conditions. The switch mounts on the fixed frame while the actuator key installs on the moving guard, ensuring a secure mechanical interlock that prevents machine startup when guards are open. All MKey models include safe interlocking as standard, with select variants offering optional locking capabilities for process or safety lock applications. Key variants include the MKEY5+ with polyester body and stainless-steel head, available with plastic or metal flex keys and 1/2 NPT cable entry. The MKEY5+ features 2NC/1NO contacts and requires 40N actuation force, making it ideal for applications requiring precise monitoring. For RFID-enabled applications, the MKEY9RF and MKEY10RF models offer M20 cable entry, OSSD outputs, and 24V solenoid operation for power-to-unlock functionality. The MKEY10RF includes a die-cast body for enhanced durability, while the MKEY9RF uses a plastic body. These switches support diverse mounting configurations and materials to meet application-specific requirements. Compliance with safety standards ensures reliable operation, and the modular design allows customization for different guard door monitoring, emergency stop integration, and safety lock applications. With dimensions of 34mm depth, 86mm height, and 54mm width, and weighing 0.299kg, the MKey series is compact yet robust, suitable for integration into existing systems without significant modifications. The MKey series is classified under UNSPSC 39122205 and is manufactured in the US, ensuring high-quality standards and compliance with industry regulations.
