The ABB 2TLA020051R5700 is a non‑contact safety sensor unit (part of the Jokab Safety “Eden” series) — specifically the “Adam OSSD‑Info M12‑8” type. It is designed for safety interlocking, door/guard locking, and safe‑position monitoring. The sensor detects a matching actuator (from the “Eva” series) without mechanical contact, eliminating wear and providing high reliability. Because it uses OSSD (Output Signal Switching Device) outputs with safety‑rated logic, it can be used with compatible safety controllers/relays for safety‑relevant functions. The compact housing, M12‑8 male connector, and robust IP67/IP69K protection make it suitable for industrial environments, including harsh or wet conditions.
