The Schmersal SE-400C is a robust safety-related tactile sensor designed for machine safety applications. This sensor ensures operational security with features like Stop category 0, electronic fuse and wire breakage detection. It's equipped to recognize short circuits and includes a start input and feedback circuit for comprehensive monitoring. Enhanced with an automatic reset function that detects the edge of a reset and allows for resetting after the supply voltage is disconnected, it also incorporates earth connection detection to prevent ground faults. The integral system diagnostics are easily monitored through two LEDs. This tactile sensor offers one undelayed semiconductor output, two safety contacts for reliable interlocking and one signalling output for status indication. Operating at 24 VDC with a power consumption of just 4 W, it can handle various loads with utilisation categories AC-15 (230 Volt AC/2 Amp) and DC-13 (24 VDC/3 Amp). Engineered by Schmersal, a leader in machine safety technology, the SE-400C series is an essential component for any safety-conscious engineering project.
