Product Overview

The 2TLA050056R2120 (Sense7Z) is coded non‑contact magnetic safety interlock switch for machine safety‑guards. It consists of sensor unit plus separate coded magnet actuator. When safety‑gate closes, magnet approaches sensor, safety contacts change state. No mechanical wear because there is no physical contact between sensor and actuator. Stainless‑steel housing is suitable for wash‑down, dusty, oil‑splashed industrial environments. LED visual indicator shows gate‑open / gate‑closed local status. Force‑guided safety contacts feed safety‑relay or safety‑PLC input for safety‑gate interlock protection.

This switch addresses machine‑safety challenges: wear‑free non‑contact gate monitoring, high‑grade PL e / SIL3 safety‑level, stainless‑steel for harsh industrial environment, drop‑in spare compatibility for existing Sense7‑series retrofit‑maintenance projects. Machine‑safety engineers, plant‑maintenance technicians and retrofit integrators benefit most. Typical applications: packaging‑machinery, press‑equipment, robot‑cell safety‑gates, offshore‑and‑process‑plant safety‑guard interlock loops.

Key Application Notes

• Non‑contact magnetic safety switch; cannot operate standalone. Must pair with matching coded Sense7Z magnet actuator and safety‑relay / safety‑PLC evaluation unit. ‑M12‑5‑pin connector variant with fixed 250 mm cable; spare replacement must match full part‑number to match contact configuration and connector style. ‑Coded‑magnet design prevents tampering by ordinary magnets. ‑IP67 rating for cabinet‑outside field‑installation; suitable for wash‑down conditions. ‑Not hot‑swap: cut off 24 VDC safety‑circuit supply before replacement. ‑Safety‑category PL e / Cat 4 requires correct dual‑channel wiring to safety‑evaluation unit. ‑Origin: Sweden; active OEM production. ‑Commissioning follow ABB Sense7Z user‑manual for switching‑distance verification and safety‑circuit validation.
