IDEM noncontact RFID coded safety switches are designed to provide interlock protection on hinged, sliding or removable guard doors. These switches are advantageous when poor guard alignment exists, when high-level antitamper is required, when high-hygiene requirements exist or when long mechanical life is required. When used in combination with a dual-channel safety relay or control device, these safety switches can provide protection up to Cat. 4 and PLe to ISO13849-1. KLP-Z, KLM-Z and KL3-Z series tongue interlock safety switches with guard locking and RFID coding fit into the leading edge of machine guard doors to provide robust guard locking while also providing a double tamper-resistant interlock mechanism.
