1. Product Overview & Safety Architecture
The Schmersal RSS 36-12-D-R-ST is a rotary-coded magnetic safety switch engineered for high-integrity access control in extreme industrial environments. Featuring a marine-grade AISI 316L stainless steel housing with IP69K protection, this device utilizes a 12-position rotary magnetic encoder (12 suffix) to detect angular actuator alignment with ±0.3° precision. The dual-channel architecture ("D" designation) achieves Category 4/PL e (ISO 13849-1) safety integrity with SIL 3 (IEC 62061) compliance, while its tamper-proof rotary coding prevents defeat per ISO 14119 Type 4 requirements. Rated for -40°C to +85°C operation and 100g shock resistance (IEC 60068-2-27), it withstands high-pressure washdowns, chemical splashes, and abrasive dust in offshore, mining, and steel processing applications. The integrated force-guided contacts ensure positive break operation even during contact welding scenarios.
