Overview

The ABB 2TLA050005R1440 mechanical safety interlock switch is a critical component for machine guarding and access control in industrial automation. This switch features a die-cast housing and a corrosion-resistant stainless steel head, ensuring durability in harsh environments with exposure to moisture, dust, and mechanical stress. It delivers a precise 12N holding force to reliably engage safety mechanisms, preventing unintended machine operation when guards are opened or access points are breached. Factory-configured with 2NC (normally closed) and 1NO (normally open) contacts, the 2TLA050005R1440 activates upon actuator insertion, providing flexible integration into safety circuits for fail-safe operation. Installation is simplified with three 1/2NPT conduit entries, enabling versatile cable routing and secure termination to meet specific wiring requirements. The switch is supplied with a durable metal flex key, enhancing operational security by preventing unauthorized access or tampering with the actuator mechanism. Designed for high-reliability applications, this switch is ideal for safeguarding conveyor systems, robotic workcells, packaging machinery, and automated production lines where adherence to stringent safety standards—such as ISO 14119 and EN 60947-5-1—is essential. The MKEY 8M series designation confirms compatibility with ABB’s MKEY actuator family, ensuring seamless integration with existing safety systems. Manufactured in the United States, this switch reflects ABB’s commitment to precision engineering and compliance with global safety regulations.
