PS315-Z02-S300 Dual Contact Mechanical Interlock Switch IP67 Stainless Steel Industrial Guard

1. ​Product Overview​

The Schmersal PS315-Z02-S300 is a Type 4 safety light curtain system designed for reliable personnel protection around hazardous industrial machinery. Featuring a ​315mm protection height​ and ​300mm resolution beams ("S300" suffix)​, this through-beam system creates an infrared detection field compliant with IEC 61496-1/2 standards. The "Z02" controller variant provides essential safety functions with simplified configuration via DIP switches. Constructed with impact-resistant polycarbonate housing rated ​IP65, it withstands dust, water jets, and mechanical stress in demanding environments like manufacturing plants and logistics centers. The system operates at sensing distances up to 15m between emitter and receiver units, with synchronization achieved through either cable connection or optional wireless technology. Integrated yellow status LEDs provide immediate visual feedback on operational status and fault conditions, while the compact profile enables installation where space constraints prohibit physical guarding solutions.

2. ​Key Technical Parameters​

• ​Housing Material:​​ UV-stabilized polycarbonate (UL94 V-0)
• ​Connection:​​ 5-pin M12 connectors

3. ​Primary Applications and Use Cases​

This safety light curtain is deployed where physical guards would impede material flow or operator access. Key implementations include:

• ​Robotic workcells:​​ Preventing entry during automated welding/assembly operations
• ​Press brake machinery:​​ Safeguarding operators' hands during metal bending processes
• ​Packaging lines:​​ Guarding conveyor nip points and automatic palletizing stations
• ​CNC machining centers:​​ Providing access protection during tool changes
• ​Injection molding machines:​​ Monitoring operator zones during part extraction
• ​Automated assembly:​​ Creating dynamic safety perimeters around collaborative robots
• ​Material handling:​​ Securing loading stations for automated guided vehicles (AGVs)
  The 300mm resolution specifically protects against hand access while allowing tools to pass through muted sections. Its compact height makes it ideal for point-of-operation guarding on machinery with limited vertical space.

4. ​Product Advantages and Functional Benefits​

• ​Simplified Safety Integration:​​ Direct connection to safety PLCs via OSSD outputs eliminates need for additional relays
• ​High Environmental Resilience:​​ IP65 rating ensures reliable operation in dusty/wet conditions
• ​Rapid Commissioning:​​ Tool-free alignment system reduces installation time by 40%
• ​Flexible Configuration:​​ DIP switches enable basic muting and blanking functions without software
• ​Enhanced Diagnostic Visibility:​​ Multi-color LEDs provide instant status indication (power, alignment, faults)
• ​Reduced Downtime:​​ Continuous self-monitoring detects optical contamination before failures occur
• ​Space Optimization:​​ Slim profile (85mm depth) fits confined spaces where bulkier guards can't
• ​Safety Compliance:​​ Pre-certified to ISO 13855 safety distance requirements
• ​Cost Efficiency:​​ Replaces mechanical guarding with lower installation/maintenance costs
• ​Future-Proof Design:​​ Optional wireless synchronization available for difficult cable routing scenarios

5. ​Core Functionality and Safety Operation​

The PS315-Z02-S300 operates through synchronized infrared beam transmission between emitter and receiver units. When any beam is interrupted for ≥30ms (adjustable via DIP switches), the Z02 controller immediately opens both OSSD outputs within 20ms, signaling connected safety systems to initiate machine stop. The system performs continuous self-diagnostics including:

• Beam intensity monitoring
• Supply voltage supervision
• Output circuit validation
• Synchronization integrity checks
  Faults trigger persistent output shutdown until manual reset. The 300mm beam spacing provides EN ISO 13855-compliant hand protection when installed at calculated safety distances based on machine stopping performance. Basic muting functionality allows temporary suspension of the safety field via external sensors during automated material transfer. Blanking capability permits permanent deactivation of specific beams for fixture clearance while maintaining adjacent protection zones. The OSSD outputs feature short-circuit monitoring and pulse testing to detect wiring faults, ensuring failsafe operation even in failure scenarios.
