Overview

The ABB 2TLA050003R1421 is a mechanical safety interlock switch designed for robust machine guarding applications, ensuring operator safety by preventing access to hazardous machinery until it is safe. This unit features a durable stainless steel housing and a stainless steel head, providing excellent resistance to corrosion and wear in demanding industrial environments. It offers a holding force of 40N, which is crucial for maintaining the secure engagement of the actuator and preventing accidental opening of safety guards during operation. The contact configuration includes 2 normally closed (NC) contacts and 1 normally open (NO) contact, suitable for safety circuits that require monitoring of guard position and signaling to control systems. The switch is equipped with three 1/2NPT conduit entries, allowing for flexible and secure wiring installations in various industrial setups. It is delivered with a metal flex key, ensuring reliable actuator insertion and removal. This interlock switch is designed for power-to-lock applications, meaning the guard cannot be opened until the machine is in a safe state and the interlock is disengaged. Similar to the ABB 2TLA050013R1444 (MKEY 8M) which also utilizes 1/2 NPT entries and a stainless steel head, this switch exemplifies ABB's commitment to safety and reliability in industrial automation. Applications include packaging machinery, material handling systems, robotics, and any equipment requiring strict adherence to safety protocols and compliance with safety standards. The UNSPSC code for this product is 39122205. Country of Origin: US.
