1. Heavy-Duty Roller Lever Safety Switch Overview
The Schmersal PS316-T12-N300 is an industrial-grade safety limit switch engineered for high-reliability position monitoring in demanding automation environments. Featuring a robust T12 roller lever actuator with ±3mm lateral tolerance, this device delivers precise mechanical actuation for safety-critical functions. Its zinc die-cast housing provides IP67 protection against dust, oils, and temporary immersion (1m depth for 30 minutes). The 300mm PVC cable (N300 suffix) offers chemical resistance while maintaining flexibility. 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. Force-guided silver-tin contacts (2NC + 2NO) handle 6A @ 250V AC loads, while the stainless steel roller lever withstands IK10 impacts (20J). Designed for stamping presses, conveyor systems, and heavy machinery, its 10-million-cycle mechanical rating ensures longevity in high-vibration industrial applications.
2. Critical Technical Specifications
This switch delivers PL d/SIL 2 safety performance with 2NC+2NO contacts rated for 6A at 250V AC. The zinc housing withstands 100g impacts (IEC 60068-2-27) and 500hr salt spray exposure (ISO 9227). Mechanical specifications include stainless steel roller lever (Ø28mm), 25° pretravel, and over-center locking mechanism. Electrical durability exceeds 100,000 cycles at full load, while the PVC cable resists acids and alkalis per ISO 1817. Environmental resilience includes IP67 protection, -25°C cold start capability, and 10g vibration resistance (10-150Hz). The T12 actuator maintains ±1mm positioning accuracy across the operating temperature range, with tool-free contact block replacement for maintenance optimization.
3. Industrial Machinery Applications
This switch excels in heavy-equipment safety systems:
- Metal Stamping Presses: Safety gate position verification per ANSI B11.2 standards
- Mining Conveyors: Emergency stop pull-cord monitoring in high-dust environments
- Robotic Welding Cells: Guard door interlocks with vibration resistance
- Automotive Assembly Lines: Fixture clamping position detection
- Material Handling Systems: Palletizer guard position confirmation
- Industrial Ovens: Access door security with thermal resilience
- Packaging Machinery: Jam detection on carton erectors
- Hydraulic Power Units: Cover position monitoring
The T12 actuator's extended lever arm (60mm) accommodates ±5mm misalignment, while zinc housing resists cutting fluids in metalworking environments. IP67 protection ensures reliability in washdown areas like food processing facilities.

5. Safety Operation Mechanism
Mechanical Safety Sequence:
- Actuator Engagement:
- Roller lever depressed (6-9N force) closes NC contacts within 20ms
- Over-center mechanism locks contacts in position
- Position Verification:
- Mechanical cam ensures positive contact operation
- Auxiliary NO contact provides position feedback
- Fault Protection:
- Welded contacts are mechanically separated (≥0.5mm gap)
- Independent NC contact guarantees safe-state shutdown
- Reset Protocol:
- Automatic reset upon lever release
- No manual intervention required
