This safety switch from Schmersal turns off a machine if its guard door is open, preventing equipment damage and injury to personnel. Its coded actuator and RFID(radio frequency identification) technology prevent interference to protect the switch against unauthorised access. As it's also suitable for series wiring, you can connect it to multiple sensors to suit your system requirements. This unit features LED signals with green, red and yellow colours to indicate supply voltage, error and sensing modes. This makes it simple to determine its status at a glance for ease of use.
