Overview

The ABB 2TLA050003R1221 is a mechanical safety interlock switch designed for critical access control and machine safeguarding in industrial environments. Constructed with a durable stainless steel housing and head, this switch offers superior resistance to corrosion, chemicals, and harsh conditions, making it ideal for washdown areas, food processing, chemical plants, and outdoor applications. The switch features a 40N holding force, ensuring secure engagement and preventing accidental opening of guarded access points during machine operation. The 2TLA050003R1221 provides a contact configuration of 2 normally closed (NC) and 1 normally open (NO) contacts, suitable for integration into safety circuits requiring positive break monitoring. Installation is streamlined with three 1/2NPT conduit entries for straightforward wiring and cable management in confined spaces. This model includes a flat key for enhanced security, preventing unauthorized operation or tampering. Key specifications include IP67 and IP69K ingress protection ratings, confirming resistance to dust ingress and high-pressure water jets. The switch meets performance level up to 'e' and is part of the MKEY 5 SS series, known for its stainless steel construction and reliable 2NC+1NO contact arrangement. Dimensions are 34mm depth, 98mm height, and 58mm width, with a net weight of 0.453kg. The unit is manufactured in the US and carries UNSPSC code 39122205. Applications include machine guarding, access control systems, robotics safety circuits, and automated production lines where material integrity and corrosion resistance are critical. The power-to-lock functionality ensures the guard remains locked when the machine is in operation and the switch is activated, maintaining operational safety and compliance with industry standards.
