Schmersal RSS260-D-ST RFID Safety Sensor

Schmersal RSS260-D-ST RFID Safety Sensor is a compact, RFID-coded electronic safety switch from the RSS 260 family, designed for safeguarding applications that require reliable protection against tampering and easy mounting. It uses universal RFID coding, supports frontal and lateral actuation, and comes in a thermoplastic enclosure with a single M8 connector for quick installation. The device operates on 24 VDC (PELV), with a rated operating current of up to 600 mA, no-load current around 35 mA, and readiness time up to 2,000 ms; it supports two safety inputs (X1, X2) and provides two OSSD safety outputs plus one diagnostic output, enabling EN IEC 60947-5-3 compliant safety circuits with diagnostic feedback. Dimensions are 40 × 18 × 29.5 mm (H × W × D), with a width of 39.2 mm, and it is rated for -25 °C to +65 °C ambient temperature and up to 93% relative humidity (non-condensing). The unit carries IP65/IP67 protection and a rated insulation voltage Ui of 32 VDC, with an impulse withstand of 0.8 kV and an electronics‑level protection class of III. The RSS260-D-ST combines RFID-based anti-tamper coding with straightforward installation and robust operation in industrial environments, making it suitable for guard-door interlocks and other safety switching needs where reliable monitoring and clear diagnostic feedback are important.
