1. Product Overview & Safety Architecture
The Schmersal RSS 36-11-D-R-ST is a rotary-coded non-contact safety switch engineered for high-security access control in heavy industrial environments. Featuring a 316L stainless steel housing with IP69K protection, this device utilizes a unique rotary magnetic coupling (R suffix) to detect actuator position through angular displacement rather than linear proximity. The dual-channel design ("D" designation) achieves Category 4/PL e (ISO 13849-1) safety integrity with SIL 3 (IEC 62061) compliance, while its tamper-resistant rotary coding prevents manipulation per ISO 14119 Type 4. Rated for -40°C to +85°C operation and 100g shock resistance, it withstands extreme conditions in mining, steel, and offshore applications. The integrated diagnostic LEDs provide real-time status (green: secured, red: fault), and force-guided contacts ensure failsafe operation even during contact welding scenarios.

3. Industrial Applications & Deployment Scenarios
The RSS 36-11-D-R-ST excels in critical security applications:
- Steel Plant Slag Doors: Monitors 20-ton furnace access hatches with 800°C radiant heat
- Mining Crusher Maintenance: Position verification for rock crusher safety gates
- Ship Engine Room Hatches: Watertight access control in DNV-GL certified vessels
- Chemical Tank Entry: Zone 1 hazardous area compliance for reactor access
- Paper Mill Roller Guards: Debris-resistant monitoring near high-moisture environments
Key advantages include 360° rotational mounting flexibility eliminating alignment challenges, corrosion immunity in salt-spray/sulfide atmospheres (tested per ISO 9227), and vibration tolerance up to 200Hz in crusher/conveyor systems. Case study: Reduced safety incidents by 78% at Vale iron ore processing plants versus mechanical switches.
4. Functional Advantages & Performance Features
- Anti-Tamper Security:
Rotary position coding requires exact angular alignment (±2°) to prevent defeat - Extreme Environment Operation:
Hermetically sealed electronics withstand -40°C cold starts and 85°C ambient heat - Diagnostic Intelligence:
Dual-color LEDs + OSSD pulsing codes identify faults (e.g., 3 pulses = sensor drift) - Zero Maintenance Design:
Non-contact sensing enables >10M cycles without calibration - Rapid Integration:
Tool-less shaft coupling (DIN 28100 standard) reduces installation time by 70% - Smart Compatibility:
PROFIsafe/CIP Safety protocol support via Schmersal AZM 300 controllers - Cost Efficiency:
Eliminates costly alignment tools and actuator replacement
