The ESPE SSR22 Series Contactless Safety Door Switch is a non‑contact RFID‑based safety interlock designed to monitor the open/closed condition of safety doors, guards, covers, and access points in automated machinery and industrial systems. Using RFID coded sensing with universal or unique coding modes, the SSR22 eliminates mechanical wear and provides reliable tamper‑resistant detection over time. Its compact IP65‑rated housing and robust protective circuitry make it suitable for various automated production, robotics, and safety gating applications.
The SSR22 meets ISO 13849‑1 Cat 4 / Performance Level e and IEC safety standards, and incorporates dual redundant OSSD outputs with self‑diagnosis and cross‑diagnosis to ensure high integrity even if a single loop fails. A magnetic holding force of approximately 15 N lets it also act as a door magnet replacement, while its low power consumption, quick response time (~50 ms), and environmental resistance support dependable safety control in industrial environments.
