Overview

ABB MKey mechanical safety switches (SKU: 2TLA050040R0604) are industrial-grade safety interlock devices designed for door and hatch monitoring in high-risk environments. These switches ensure machinery remains de-energized when guards or access panels are open, providing critical safety interlocking functions. The system consists of a fixed switch mounted on the frame and a compatible actuator key attached to the moving guard, enabling automatic detection of guard position with high reliability. Key variants include MKEY9RF (plastic body, stainless steel head), MKEY10RF (die-cast body, stainless steel head), and MKEY8ZRF (stainless steel body and head), all featuring RFID technology, M20 cable entry, and OSSD outputs for direct integration with safety control systems. The 24V solenoid unlocking mechanism allows for remote-controlled access, making these switches suitable for both process locks and safety locks depending on configuration. The MKEY10RFER model includes rear release and 4-button mounting for enhanced installation flexibility. Available in multiple material configurations—plastic, die-cast, and stainless steel—these switches are engineered to withstand harsh industrial conditions, including exposure to chemicals, extreme temperatures, and mechanical stress. The stainless steel variants (MKEY8ZRF) offer superior corrosion resistance for food processing, pharmaceutical, or marine applications. All models comply with stringent safety standards for reliable performance in machine guarding applications. Typical applications include automated production lines, robotic cells, material handling systems, and industrial machinery where operator safety and equipment protection are paramount. The MKey series ensures compliance with machinery safety directives while providing durable, low-maintenance operation with minimal downtime. The MKEY4 variant offers a rugged polyester housing, 2NC+1NO outputs, and IP67 protection, with options for metal or plastic flex keys and holding forces of 12N or 40N.
  • Rugged polyester, die-cast, or stainless steel construction for harsh environments
  • RFID technology with OSSD outputs for direct safety control system integration
  • 24V solenoid unlocking for remote-controlled access (process or safety lock modes)
  • IP67-rated protection against dust and water ingress
  • 2NC+1NO outputs with holding forces of 12N or 40N (MKEY4 variants)
