1. Safety-Integrated Guard Locking System Overview
The Schmersal SLG440AS-ER-0500-02 is an advanced electromechanical interlock designed for machinery requiring guarded access with emergency egress capability. Featuring a mechanically coded locking mechanism with 50mm bolt throw ("0500" suffix), this IP69K-rated device integrates dual-channel safety contacts and solid-state OSSD outputs for ISO 13849-1 PL e (Category 4) compliance. The "ER" designation enables emergency mechanical release via 70N inward force, while "AS" provides ±15mm lateral tolerance compensation via eccentric adjusters. Constructed with glass-fiber reinforced PBT housing (UL94 V-0) and stainless steel latch, it withstands 150°C temperatures, high-pressure washdowns, and industrial vibrations. Integrated diagnostics monitor bolt position with ±0.1mm resolution, and tamper-resistant M12 connectors ("02" coding) ensure secure wiring in robotic cells, stamping presses, and chemical processing applications.
2. Critical Performance Specifications
This interlock operates at 24-240V AC/DC with dual NC/NO contacts (5A @ 250V AC) and two OSSD outputs (PFD 4.2×10⁻⁹). The 1500N locking force (EN ISO 14119) secures guards against accidental opening, while emergency release activates in <80ms without power. Mechanical specifications include 10mm locking pin diameter, ±15mm lateral tolerance adjustment, and 500,000-cycle durability. Environmental resilience includes IK10 impact resistance (20J), 100-bar water jet protection (IP69K), and operation from -40°C to +150°C. Materials feature zinc-plated steel bases and V4A stainless actuators, with certifications covering ATEX/IECEx Zone 21, UL 508, and GOST standards. Anti-tamper magnetic coding (ISO 14119 Level 4) prevents bypass with >100,000 unique key combinations.
3. Industrial Hazard Mitigation Applications
This interlock safeguards high-risk machinery requiring emergency egress:
- Robotic Workcells: Locked access during AUTO mode with panic release for trapped operators
- Metal Stamping Presses: Guard securing during production with instant override for jam clearance
- Chemical Reactors: Explosion-proof isolation during maintenance interventions
- HVAC Systems: Fan guard locking in 150°C exhaust ducts with thermal expansion compensation
- Pharmaceutical Autoclaves: Sterile chamber access with cleanroom-compatible materials
- Cryogenic Freezers: -40°C operation with ice-jam release capability
- Plastic Injection Molding: Dual-mode protection during die changeovers
- Turbine Halls: Vibration-resistant alignment (±15mm tolerance) for generator enclosures
Its 5m PUR cable accommodates guard displacement from thermal expansion in ovens/reactors.
4. Engineered Safety Advantages
- Emergency Mechanical Release: Spring-loaded shear-pin mechanism operates independently of electronics
- Thermal Resilience: Sustains 500+ cycles between -40°C and +150°C (EN 60068-2-14)
- Anti-Vibration Design: Maintains alignment under 10g vibration (IEC 60068-2-6)
- High-Pressure Immunity: 100-bar water jet protection (DIN 40050-9)
- Corrosion Defense: >2000hr salt spray resistance (ISO 9227)
- Overload Protection: Shear pin breaks at >1500N force to prevent structural damage
- Real-Time Diagnostics: Hall-effect sensors monitor bolt position at 5kHz sampling rate
- Coding Security: Magnetically coded discs prevent unauthorized duplication
- Maintenance Optimization: Tool-free coding disc replacement and LED status indicators
5. Safety Operation & Diagnostics Protocol
Guard Locking Sequence:
- Secure Mode Activation:
- Enable signal energizes solenoid → bolt extends within 15ms
- Hall sensors verify full extension before permitting machine operation
- Emergency Override:
- 70N inward force on guard shears security pin
- Spring mechanism retracts bolt independently within 80ms
- NC contacts open circuit to initiate Category 0 stop
- Diagnostic Monitoring:
- Solid Green LED: Guard locked and secured
- Flashing Red LED: Emergency release activated
- Alternating Red/Yellow: Bolt jam detected
- Solid Yellow: Coding mismatch or tampering attempt
- Reset Protocol:
- Physical guard reclosure required
- Reset button press after fault clearance
- System performs 100ms self-test (contact/position verification)
Safety Architecture:
- Dual-processor cross-monitoring with ≤10ms response time
- Force-guided contacts guarantee ≥0.5mm separation during faults
- Undervoltage lockout below 20V DC
- Automatic bolt position calibration at power-up
