Product Description

1. Product Overview & Safety Architecture

The ​Schmersal RSS16-D-ST8H​ is a non-contact magnetic safety switch engineered for high-integrity guard door monitoring in heavy industrial environments. Featuring a ​stainless steel housing (AISI 316L)​​ and IP69K-rated sealing, this device utilizes redundant Hall-effect sensors to detect coded magnets (ST8H actuator) with ±0.5mm positional accuracy. The "D" suffix denotes dual-channel OSSD outputs achieving ​Category 4/PL e (ISO 13849-1)​​ safety integrity, while the ST8H actuator incorporates tamper-proof RFID coding to prevent bypass attempts. Rated for ​SIL 3 (IEC 62061)​​ and ​ATEX Zone 2/22 (II 3G Ex tc IIIC T85°C Dc)​, it delivers failsafe machine shutdown within 15ms via force-guided contacts. With an operational temperature range of -40°C to +85°C, it withstands high-pressure washdowns and chemical exposure in food/pharmaceutical applications.


2. Critical Technical Specifications

  • Electrical Parameters:
    • Supply Voltage: 24V DC ±10%
    • Safety Outputs: 2 OSSD PNP (3A @ 30V DC)
    • Leakage Current: <0.1mA (EN 60947-5-3)
  • Mechanical Properties:
    • Switching Distance: 16mm nominal (ST8H actuator)
    • Actuator Force: ≤5N (zero mechanical wear)
    • Shock Resistance: 100g (IEC 60068-2-27)
  • Environmental Resilience:
    • Housing: AISI 316L stainless steel
    • Protection: IP69K (100-bar water/steam resistant)
    • Chemical Resistance: Resists acids/alkalis (pH 1-14)
  • Certifications:
    • ATEX/IECEx II 3G Ex tc IIIC T85°C Dc
    • UL 1203 (Class I Div 2)
    • EHEDG G8 hygienic design

3. Industrial Applications & Deployment Scenarios

The RSS16-D-ST8H excels in critical safety monitoring:

  • Automotive Robotic Cells: Securing FANUC M-710ic access doors with RFID-coded actuators to prevent defeat
  • Food Packaging Lines: Monitoring filler machine guards exposed to CIP/SIP cleaning cycles
  • Pharmaceutical Isolators: Ensuring airtight containment in Grade A/B cleanrooms
  • Chemical Mixing Stations: Zone 2 hazardous area compliance for solvent handling
  • Mining Conveyors: Dust-ingress resistant position feedback for transfer chutes
    Key advantages include ​corrosion immunity​ in salt-spray environments (tested per ISO 9227), ​vibration tolerance​ up to 55Hz @ 25 m/s², and ​EMC immunity​ (30V/m per EN 61000-6-2). Case study: Reduced false trips by 92% at BASF polymer plant versus mechanical switches.

4. Functional Advantages & Performance Features

  • Zero Maintenance Operation:
    Contactless sensing eliminates mechanical wear → 10M+ cycles without calibration
  • Advanced Diagnostics:
    Dual-color LED indicators (green=locked, red=fault) + OSSD status feedback to PLC
  • Rapid Integration:
    Tool-less mounting (M5 bolts) and plug-and-play M12 connectors (5-pin A-coded)
  • Safety Logic Integrity:
    Cross-monitored detect sensor mismatches/field distortion within 2ms
  • Cost Efficiency:
    50% faster installation vs. mechanical switches + no actuator lubrication required
  • Smart Compatibility:
    Pre-configured for PROFIsafe/CIP Safety protocols via Schmersal AZM 300 controllers
