The RFID-coded safety sensor offers the highest protection (up to PLe SIL3) against tampering due to unique actuator coding. With no moving parts, the design is wear-free for minimal required maintenance over the long service life of the product. It provides intrinsically safe OSSD outputs with no fail-safe relay required. It allows series connection of up to 32 codable and uniquely coded sensors without losing safety integrity. Clearly visible LEDs display the operating status and diagnostics.
