Overview

The ABB MKey Mechanical Safety Switch, SKU 2TLA050040R0506, is engineered by ABB Electrification for reliable monitoring of doors, hatches, and other movable guards in industrial safety applications. This switch ensures safe interlocking as a standard feature across all models, with specific variants offering optional locking functions for process or safety lock configurations. The MKey system comprises a fixed switch unit and a corresponding actuator key, designed for precise alignment and secure operation. Available catalog numbers like 2TLA050001R1400 (MKEY4, polyester housing, 2NC/1NO contacts, IP67, 12N holding force) and 2TLA050005R1530 (MKEY6, die-cast housing, 2NC/1NO contacts, IP67, 12N holding force) highlight material and housing options. These switches are rated for performance levels up to 'e' and feature 2 normally closed (NC) and 1 normally open (NO) contact outputs. The MKey series supports 3 x 1/2" NPT conduit entries for flexible installation. Dimensions vary by model, with examples including 34mm (L) x 86mm (H) x 54mm (W) for some polyester variants and 42mm (L) x 118mm (H) x 40mm (W) for die-cast models. The product net weight is approximately 0.299kg to 0.400kg. The MKey switches are designed for integration with safety relays and safety PLCs, making them suitable for automated systems and machinery with extended stopping times. The robust construction and specific material choices, such as stainless steel heads and die-cast bodies, ensure durability in demanding industrial environments. Applications include interlocking movable guards on manufacturing floors and within automation systems.
