Here is the technical description for Schmersal PS315-T11-S300 Safety Limit Switch:
1. Product Overview
The Schmersal PS315-T11-S300 is a heavy-duty safety limit switch engineered for high-reliability position monitoring in industrial automation. Featuring a T11 roller lever actuator with ±2mm repeatability, this device delivers precise mechanical actuation for safety-critical applications. Its zinc die-cast housing provides IP67 protection against dust, oils, and temporary immersion, while the 300mm PUR cable (S300 suffix) enables flexible installation. Certified to ISO 13849-1 PL d (Category 3) and IEC 62061 SIL 2, it operates across 24–240V AC/DC within -25°C to +70°C environments. The force-guided silver-cadmium contacts (2NC + 2NO) handle 6A @ 250V AC loads, while the stainless steel roller lever withstands IK10 impacts (20J). Designed for stamping presses, automated gates, and material handling systems, its 10-million-cycle mechanical rating ensures durability in demanding industrial environments.

Self-lubricating pivot (10-year service life)
5. Safety Operation & Diagnostics
Mechanical Actuation Sequence:
- Lever Engagement:
- Roller depressed (4–6N force) → NC contacts close within 15ms
- Position Locking:
- Over-center mechanism secures contacts against vibration
- Fault Detection:
- Contact welding forces mechanical separation (>0.5mm gap)
- Auxiliary NO contact signals lever position
- Reset Protocol:
- Automatic reset upon lever release
- No manual intervention required
Diagnostic Features:
- Visual Inspection Window: Verifies contact status
- Force-Guided Design: Guarantees contact separation during faults
- Environmental Testing: Validated for 500hr salt spray (ISO 9227)
