,Mechanical Interlock with dual contact
1. Product Overview & Core Safety Technology
The Schmersal CSS 8-180-2P-E-L is a compact rotary-coded safety switch engineered for space-constrained machinery guarding. Featuring an aluminum housing (ALSi9Cu3 alloy) with IP67 protection, this device utilizes a 180° rotary cam actuator to monitor guard positions with ±0.5° precision. The "2P" designation indicates dual positive-break NC contacts achieving Category 3/PL d (ISO 13849-1) safety integrity, while the "E" suffix denotes emergency release functionality via mechanical override key. Integrated solenoid locking ("L") provides 8kN holding force to secure access points. Rated for -25°C to +70°C operation and 30 m/s² vibration resistance (IEC 60068-2-6), it delivers reliable performance in robotic cells, CNC enclosures, and packaging machinery where panel space is limited.
2. Critical Technical Specifications
- Electrical Parameters:
- Voltage Range: 24V DC ±10% (solenoid/electronics)
- Safety Contacts: 2 NC (3A @ 230V AC)
- Lock Power: 6W (hold) / 15W (engage)
- Mechanical Properties:
- Actuator Rotation: 180° ±1°
- Locking Force: 8,000N (EN ISO 14119)
- Roller Material: Stainless steel Ø18mm
- Environmental Resilience:
- Housing: Anodized aluminum (EN AW 6082)
- Protection: IP67 (immersion to 1m)
- Chemical Resistance: Resists coolants (ISO 6743-9)
- Certifications:
- UL 508 (File E47853)
- IECEx Ex tb IIIB T80°C Db
- EN 60947-5-1 Annex K
3. Industrial Applications & Deployment Scenarios
This switch excels in compact automation systems:
- Robotic Welding Cells: Guarding KUKA KR AGILUS work envelopes
- CNC Machining Centers: Tool-changer access monitoring
- Pharmaceutical Blister Packers: Hygienic guarding in GMP environments
- Conveyor Transfer Points: Position feedback for diverters/mergers
- Electronic Assembly: ESD-safe guarding for PCB handling
Key advantages include 180° actuator flexibility eliminating alignment challenges, tool-free contact block replacement reducing MTTR by 80%, and compact 60×40×25mm dimensions fitting DIN rail enclosures. Case study: Reduced safety system footprint by 40% at Siemens automotive controller line.
4. Functional Advantages & Performance Differentiation
- Space Optimization:
60mm width saves 50% panel space vs standard safety switches - Emergency Release:
Mechanical override unlocks during power failure (OSHA 1910.147 compliant) - Positive-Break Security:
Forced contact separation prevents welded-contact failures - Maintenance Efficiency:
Tool-less cam angle adjustment (±15°) via calibrated dial - Vibration Tolerance:
Shock-absorbing roller bearings withstand 30 m/s² impacts - Cost Efficiency:
Direct replacement for legacy switches without panel modification - Diagnostic Visibility:
Dual-color LED (green=locked/red=fault) enables rapid troubleshooting
5. Safety Logic & Operational Sequence
Operation follows three-stage workflow:
- Guard Closure:
Rotary cam rotates actuator to 0° position (±0.5°) - Lock Engagement:
Solenoid extends bolt into guard strike plate - Contact Verification:
Positive-break NC contacts close only when lock is fully engaged
Fault Responses:
- Cam misalignment >2° → lock prevention
- Power loss → spring-retract lock release
- Contact welding → forced separation via mechanical override
Recovery requires manual reset after fault clearance.
