Ps315-Z11-S200 Mechanical Interlock Safety Switch IP67 Stainless Steel Industrial Guard

1. Product Overview

​
The Schmersal PS315-Z11-S200 is an advanced Type 4 safety light curtain system designed for personnel protection around hazardous machinery per IEC 61496 standards. This through-beam system consists of a transmitter (emitter) and receiver unit creating an infrared protection field with 200mm resolution ("S200" suffix). The "Z11" controller variant features integrated safety logic with configurable functions including muting, blanking, and restart interlock. Built with robust polycarbonate housing rated IP65, it withstands industrial environments with dust, moisture, and mechanical impacts. The system operates with a sensing range up to 30m and features synchronized operation via cable or wireless synchronization options. Yellow status LEDs provide clear operational feedback, while the compact profile (height: 315mm) enables installation in space-constrained areas. Designed for Category 4 safety circuits per ISO 13849-1, it provides reliable access prevention to dangerous zones in automated equipment.

​3. Primary Applications and Use Cases

​
The PS315-Z11-S200 is essential for safeguarding hazardous zones in industrial automation. It protects operators near robotic welding cells by stopping robots when limbs enter the detection field. In press brake operations, it prevents hand injuries during metal forming processes. Packaging machinery utilizes it to guard feeding stations and conveyor nip points. Additional critical applications include:

• Access prevention to CNC machining centers during operation
• Perimeter guarding for automated assembly lines
• Material handling equipment safety zones
• Plastic injection molding machine gate protection
• Palletizing system human-robot collaboration areas
  Its 200mm resolution specifically protects against hand/finger access while allowing tooling to pass through muted sections. The compact height makes it ideal for guarding lower-risk areas where full-height barriers are impractical.

​4. Product Advantages and Functional Benefits​

• ​Flexible Configuration:​​ Integrated muting/blanking allows temporary suspension for material handling
• ​High Immunity:​​ Resists false triggers from ambient light (≤40,000 lux) and industrial EMI
• ​Diagnostic Capabilities:​​ Continuous self-monitoring with fault memory storage
• ​Reduced Wiring:​​ Daisy-chaining capability minimizes control cabinet connections
• ​Quick Installation:​​ Alignment indicators simplify transmitter-receiver setup
• ​Safety Integrity:​​ Dual OSSD outputs enable Category 4 safety circuits
• ​Maintenance Savings:​​ Dust-resistant optics require minimal cleaning
• ​Adaptive Protection:​​ Configurable protective field heights (via blanking)
• ​Global Compliance:​​ Meets ISO 13855 safety distance requirements

​5. Core Functionality and Safety Operation

​
The system creates an infrared matrix between transmitter and receiver. When any beam is interrupted (≥100ms), the Z11 controller immediately opens both OSSD outputs within 20ms, signaling connected safety relays or PLCs to initiate machine stop. The controller continuously performs 13 self-tests including LED monitoring, circuit integrity checks, and synchronization verification. Muting functionality allows temporary suspension of the safety field via external sensors during material transfer - automatically reactivating when objects clear the zone. Blanking enables permanent deactivation of specific beams for fixture clearance while maintaining adjacent protection. The restart interlock prevents automatic reset after beam interruption, requiring deliberate restart confirmation. All configurations are set via DIP switches with clear function indicators. The 200mm beam spacing provides EN ISO 13855-compliant finger/hand protection when installed at proper safety distances calculated per machine stopping performance.
