PS316-Z11-K370 Mechanical Interlock Single Contact Switch IP67 Aluminum Industrial Guard

1. ​Product Overview​

The Schmersal PS316-Z11-K370 is an advanced Type 4 safety light curtain engineered for demanding industrial applications requiring adaptive protection fields and high-resolution detection. Featuring a ​316mm protection height​ and ​370mm resolution beams ("K370" suffix)​, this system incorporates a patented ​kinematic mounting system​ that compensates for ±15° angular misalignment during installation or thermal drift. The "Z11" controller integrates sophisticated safety logic including configurable muting sequences, floating blanking, and cascading capabilities. Encased in rugged ​UV-stabilized polycarbonate housing (IP65 rated)​, it withstands harsh environments with exposure to oils, coolants, metal dust, and high-pressure washdowns. Synchronization via cable or optional RF technology enables reliable operation at distances up to 30m. Integrated multicolor LEDs provide real-time status feedback for alignment quality, operational state, and diagnostic conditions, while M12 connectors ensure rapid installation in automated production environments.

3. ​Primary Applications and Use Cases​

This system excels in complex industrial scenarios requiring flexible safeguarding solutions:

• ​Robotic machining cells:​​ Protecting operators near articulated robots with variable work envelopes
• ​Automated press lines:​​ Safeguarding angled stamping operations where conventional light curtains misalign
• ​Automotive body shops:​​ Creating dynamic protection zones around curved welding fixtures
• ​CNC milling centers:​​ Guarding multi-axis tool changers with irregular access points
• ​Packaging machinery:​​ Securing irregularly shaped product infeed stations
• ​Forging operations:​​ Maintaining protection despite thermal expansion-induced frame distortion
• ​Plastic extrusion lines:​​ Monitoring access to heating elements on warped machinery frames
• ​AGV charging stations:​​ Creating adaptive safety fields around docking mechanisms
  The kinematic mounting system uniquely compensates for machinery settling, thermal deformation, and installation tolerances that would compromise conventional systems. Its 370mm resolution provides optimal balance between intrusion prevention and material flow requirements in high-cycle applications.

• ​Future-Proof Design:​​ Field-upgradable to wireless synchronization and IoT connectivity

5. ​Core Functionality and Safety Operation​

The PS316-Z11-K370 operates through synchronized pulsed infrared transmission between emitter and receiver units. Its kinematic mounting system employs spring-loaded prismatic joints that dynamically maintain optical alignment across ±15° deflection angles. When any beam interruption exceeds 30ms (configurable), the Z11 controller opens both OSSD outputs within 20ms, initiating machine stop via connected safety systems. Continuous self-diagnostics monitor:

• Beam deflection angles via integrated inclinometers
• Synchronization signal integrity
• Output circuit continuity through 1kHz pulse testing
• Voltage stability within ±5% tolerance
  The system's floating blanking function dynamically deactivates beams obscured by fixed obstructions while maintaining adjacent protection zones. Cascading capability enables synchronization with up to 3 additional units for extended protection fields. The OSSD outputs feature short-circuit monitoring with automatic shutdown upon fault detection. Reset requires deliberate confirmation after fault resolution, ensuring compliance with ISO 14121 risk assessment principles. The kinematic system maintains <0.3° beam divergence throughout its compensation range, providing consistent detection reliability despite vibration or thermal cycling.
