Overview

The Sick T40-E0101K is a transponder-based non-contact safety switch from the T4000 Direct product line. Rated PLe Cat4 type 4, this RFID safety interlock switch detects magnet-coded actuators and provides fail-safe control for personnel protection and machine guarding in industrial automation environments. The T40-E0101K is a sensor-only unit; the matching actuator must be ordered separately.
