Product Description

1. ​Heavy-Duty Safety Interlock Overview

The Schmersal RSS 36-ST-AS is a ​stainless steel magnetic safety switch​ engineered for extreme industrial environments requiring high corrosion resistance. Featuring a ​36mm switching distance​ and ​​±3mm lateral tolerance, this device utilizes ​non-contact magnetic technology​ to monitor guard positions without mechanical wear. Its ​IP69K-rated AISI 316L housing​ withstands temperatures from ​​-30°C to +85°C, high-pressure washdowns (100 bar), and aggressive chemicals (pH 1-14). Certified to ​ISO 13849-1 PL e (Category 4)​​ and ​IEC 62061 SIL 3, the "AS" suffix denotes ​adjustable mounting brackets​ for simplified alignment. Integrated ​dual-color LEDs​ provide visual status (green = secured, red = fault), while the crevice-free design meets EHEDG standards for hygienic industries like food processing, pharmaceuticals, and chemical manufacturing where daily sanitation is mandatory.

2. ​Critical Technical Parameters

  • Safety Ratings:
    • PL e (ISO 13849-1 Cat. 4) / SIL 3 (PFHD: 1.8×10⁻⁹/h)
  • Electrical Specifications:
    • Voltage: 24V DC ±10%
    • Contacts: 2 NC force-guided (6A @ 250V AC)
    • Power Consumption: ≤2.2W
  • Sensing Performance:
    • Switching Distance: 36mm ±1mm
    • Lateral Tolerance: ±3mm (adjustable to ±5mm)
  • Mechanical:
    • Housing: Electropolished SS316L (Ra ≤0.8μm)
    • Actuator: Encrypted ferrite magnet array
  • Environmental:
    • IP69K (IEC 60529)
    • Chemical Resistance: Resists acids/alkalis/solvents
  • Certifications:
    • 3-A Sanitary Standard 08-19
    • ATEX Zone 21/22

3. ​Industrial Applications

This switch excels in corrosive/washdown environments:

  • Food Processing: CIP washdown zones on meat cutting conveyors
  • Pharmaceutical Isolators: Sterile transfer hatches with autoclave compatibility
  • Chemical Reactors: Acid vapor-resistant access doors
  • Marine Equipment: Saltwater-proof safety gates on offshore platforms
  • Automotive Paint Shops: Solvent-resistant robotic cell guarding
  • Wastewater Treatment: Sludge tank covers with H₂S resistance
  • Dairy Processing: Yogurt filling line guard doors
  • Mining Crushers: Dust-immersion protection (IP6X)
    Its IP69K rating ensures reliable operation during daily high-pressure sanitation cycles with caustic cleaners, while SIL 3 diagnostics prevent undetected failures in high-risk machinery.

4. ​Functional Advantages

  • Corrosion Defense:
    • Electropolished SS316L resists chloride stress corrosion
    • Hermetic epoxy encapsulation of electronics
  • Tamper Resistance:
    • Torque-monitored security screws (5Nm)
    • Shielded magnet defeats external bypass attempts
  • Diagnostic Intelligence:
    • Green LED: Guard closed/secure
    • Red LED: Actuator misalignment >2mm
  • Installation Flexibility:
    • Slotted mounting holes enable ±5mm adjustment
    • 360° visible LED indicators
  • Safety Redundancy:
    • Dual-processor cross-monitoring
    • Force-guided contacts guarantee ≥0.5mm separation
  • Lifecycle Durability:

    8 million non-contact operations
    Hot-swappable actuator replacement

5. ​Safety Operation & Diagnostics

Magnetic Interlock Sequence:

  1. Guard Closure:
    • Actuator aligns within 36mm → reed contacts close
    • Green LED illuminates within 100ms
  2. Continuous Monitoring:
    • Hall sensors track position (±0.5mm accuracy)
    • Current sensors detect contact anomalies
  3. Fault Response:
    • 2mm displacement forces contacts open

    • Red LED activates at >1mm misalignment
  4. Reset Protocol:
    • Physical guard reclosure required
    • Automatic self-test verifies contact separation

Diagnostic Hierarchy:

  • Solid Green: Normal operation (guard secured)
  • Flashing Green: Actuator approaching detection range
  • Solid Red: Critical fault (misalignment/contact welding)
  • Flashing Red: Reset required after fault clearance
  • LED Off: Power loss

SIL 3 Safety Architecture:

  • Dual ARM Cortex-M0+ processors
  • 10ms watchdog timer
  • Safe-state output on undervoltage (<20V DC)
  • Mechanical contact separation >0.5mm
