PS315-Z11-H300 - Inductive PNP Switch - IP67 SS 30mm Industrial Proximity Sensor

1. Heavy-Duty Industrial Safety Switch Overview​

The Schmersal PS315-Z11-H300 is a rugged safety limit switch engineered for extreme industrial environments requiring high mechanical durability. Featuring a ​hardened zinc die-cast housing (H suffix)​​ with ​IP67 protection, this device withstands impacts up to ​IK10 (20J)​​ and temporary immersion (1m depth for 30 minutes). Its ​Z11 roller lever actuator​ provides ​​±1mm repeat accuracy​ with ​5-8N operating force, while the ​300mm PUR cable​ 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 ​​-30°C to +80°C. Force-guided AgNi contacts (2NC+2NO) handle 6A @ 250V AC loads, and the stainless steel roller lever resists abrasive wear. Designed for stamping presses, mining equipment, and heavy machinery, its 10-million-cycle rating ensures reliability under continuous mechanical stress with UL 508 and IECEx Ex ec IIIC T80°C Dc certifications.

​2. Critical Performance Specifications​

This switch delivers PL d/SIL 2 safety performance with 2NC+2NO contacts rated for 6A at 250V AC. The hardened zinc housing withstands 150g impacts (IEC 60068-2-27) and 500hr salt spray exposure (ISO 9227). Mechanical specifications include stainless steel roller lever (Ø25mm), 20° pretravel, and over-center locking mechanism. Electrical durability exceeds 100,000 cycles at full load, while the PUR cable resists oils and UV degradation per ISO 1817. Environmental resilience includes IP67 protection, -30°C cold start capability, and 10g vibration resistance (10-150Hz). The Z11 actuator maintains ±0.5mm positioning accuracy across the temperature range, with tool-free contact block replacement for maintenance optimization.

​3. High-Impact Industrial Applications​

This switch excels in punishing industrial environments:

• ​Metal Stamping Presses: Safety gate monitoring with anti-repeat logic per ANSI B11.2
• ​Mining Conveyors: Emergency stop pull-cord position verification in dust-heavy conditions
• ​Forging Equipment: Die guard interlocks with vibration immunity (up to 10g acceleration)
• ​Waste Processing: Shredder access security with impact-resistant construction
• ​Steel Mill Cranes: Hook approach limit detection in high-temperature zones
• ​Wood Processing: Chipper guard monitoring with chip/debris resistance
• ​Port Machinery: Container spreader lock position confirmation
• ​Automotive Robotic Lines: Fixture guarding with 300N lateral load capacity
  The hardened housing withstands tool impacts and abrasive particles in metal processing, while IP67 protection maintains functionality during equipment washdowns in foundries or food processing plants.

​4. Engineered Durability Advantages​

• ​Impact Resistance:
  Hardened zinc alloy housing survives 150g mechanical shocks
  Triple-sealed stainless steel shaft blocks abrasive contaminants
• ​Vibration Immunity:
  Over-center mechanism maintains contact position under 10g vibration
  IGUS® polymer bushings dampen 15-55Hz oscillations
• ​Electrical Reliability:
  Silver-nickel contacts prevent welding during 10A inrush currents

  8mm creepage distance prevents carbon tracking

• ​Corrosion Defense:
  500hr salt spray resistance (ISO 9227)
  UV-stabilized PUR cable resists hydrolysis
• ​Safety Integrity:
  Positively driven contacts (EN 50205 certified)
  Cross-monitored circuits detect contact faults
• ​Maintenance Optimization:
  Tool-free contact block replacement in <30 seconds
  Self-lubricating pivot requires no maintenance

​5. Safety Operation Mechanism​

​Mechanical Safety Sequence:

1. ​Positive Actuation:
   • Roller lever depression (5-8N force) closes NC contacts within 20ms
   • Over-center cam mechanically locks contact position
2. ​Failsafe Release:
   • Lever return forces NO contacts open → NC contacts positively open
   • Guaranteed ≥0.75mm contact separation
3. ​Fault Protection:
   • Welded contacts are mechanically overridden by cam action
   • Auxiliary NO contact provides "guard open" status to PLCs
     ​Environmental Resilience:

• ​Thermal Compensation: Maintains ±0.15mm accuracy from -30°C to +80°C
• ​Sealing System: Withstands 1,000+ high-pressure washdown cycles
• ​Vibration Performance: Validated per IEC 60068-2-6 (10-150Hz/1.5mm amplitude)
  ​Reset Protocol: Automatic contact reset upon lever release with no manual intervention required
