1. Product Overview & Safety Architecture
The Schmersal RSS 36-D-ST is a non-contact magnetic safety switch engineered for heavy-duty industrial access guarding. Featuring a zinc die-cast housing with IP67 protection, this device utilizes redundant Hall-effect sensors to detect magnetic actuators at up to 36mm switching distance. The "D" designation signifies dual-channel OSSD outputs achieving Category 4/PL e (ISO 13849-1) safety integrity, while force-guided contacts ensure positive break operation even during contact welding. Rated for SIL 3 (IEC 62061) and operational from -30°C to +85°C, it withstands vibration (50 m/s²) and mechanical shock (100g) in foundries, mining, and material handling systems. The integrated tamper-proof design prevents actuator manipulation per ISO 14119 Type 4 requirements.
2. Critical Technical Specifications
- Electrical Parameters:
- Voltage Range: 24V DC ±10%
- Safety Outputs: 2 OSSD PNP (2A @ 30V DC)
- Leakage Current: <0.5mA (EN 60947-5-3)
- Mechanical Properties:
- Switching Distance: 36mm nominal (ST actuator)
- Actuator Force: ≤10N
- Housing Material: ZL3 zinc alloy
- Environmental Resilience:
- Protection: IP67 (temporary immersion)
- Chemical Resistance: Resists oils/coolants (ISO 6743-9)
- Shock/Vibration: 100g / 50 m/s² (IEC 60068-2-6/27)
- Certifications:

- IECEx Ex tb IIIC T80°C Db
- DNV-GL marine approval
3. Industrial Applications & Deployment Scenarios
The RSS 36-D-ST excels in harsh environments requiring robust safety monitoring:
- Steel Mills: Monitor slag door positions near 800°C ambient heat sources
- Mining Conveyors: Position feedback for transfer stations with coal dust ingress
- Paper Processing: Guard rotary cutters exposed to high humidity and pulp debris
- Automotive Stamping: Perimeter guarding for 2,000-ton presses
- Port Cranes: Access control for maintenance hatches in salt spray environments
Key advantages include extended sensing range enabling flexible mounting in misalignment-prone installations, zero mechanical wear for maintenance-free operation, and conformal-coated PCBs preventing condensation failures. Case study: Achieved 99.7% uptime in ArcelorMittal hot-rolling mills versus mechanical limit switches.
4. Functional Advantages & Performance Features
- High Tolerance Alignment:
±8mm lateral deviation allowance reduces installation precision requirements - Predictive Diagnostics:
Dual-color LED (green=secured, yellow=misaligned, red=fault) enables preemptive maintenance - Safety Logic Integrity:
Cross-monitored detect magnet displacement >5mm within 20ms - Corrosion Defense:
Chromate-plated housing withstands 1,000hr salt spray (ISO 9227) - Retrofit Compatibility:
Direct replacement for legacy mechanical switches (e.g., Allen-Bradley 802T) - Cost Efficiency:
40% lower installation time with M12 quick-connect terminals
5. Safety Function Workflow
The RSS 36-D-ST operates via four-stage safety logic:
- Authentication: Detects ST-series actuator magnetic signature
- Position Validation: Monitors field symmetry (±10% tolerance)
- Output Control: Energizes OSSDs only when guard is fully closed
- Fault Response:
- Magnet removal → immediate de-energization (<20ms)
- Sensor mismatch → latch-and-hold state requiring manual reset
- Voltage drop → safe-state shutdown
Diagnostic codes output via OSSD pulsation patterns (e.g., 3 flashes = sensor drift).
