PS215-T11-K240 Mechanical Interlock Single Contact Switch IP67 Aluminum Industrial Guard

1. ​Product Overview​

The Schmersal PS215-T11-K240 is a ​Type 4 safety light curtain​ (IEC 61496-1/2 certified) engineered for space-constrained industrial applications requiring reliable personnel protection. Featuring a ​compact 215mm protection height​ and ​240mm resolution beams ("K240" suffix)​, this system incorporates ​kinematic mounting technology​ (±15° vertical alignment tolerance) to compensate for installation misalignment and machinery vibration. The "T11" controller integrates advanced safety logic including configurable muting sequences, floating blanking, and restart interlocks. Housed in rugged ​polycarbonate (IP65 rated)​, it withstands industrial contaminants like metal dust, coolants, and high-pressure washdowns. Synchronization via cable or optional RF modules supports detection ranges up to ​15m. Integrated multicolor LEDs provide real-time status for alignment, operation, and diagnostics, while M12 connectors enable rapid integration into safety control systems.

3. ​Primary Applications and Use Cases​

This compact system excels in confined automation environments:

• ​Robotic assembly cells: Guarding collaborative robot work envelopes where space is limited
• ​CNC lathes/chucking machines: Protecting operators during tool changes and part handling
• ​Electronic component assembly: Securing SMT pick-and-place machine access points
• ​Pharmaceutical packaging: Monitoring tablet counting and blister sealing stations
• ​Small press brakes: Safeguarding finger zones in benchtop metal forming
• ​Laboratory automation: Providing safety perimeters around analytical instruments
• ​Conveyor transfer points: Detecting personnel at compact merge/sort modules
  The kinematic mount compensates for frame deflection in machinery like injection molding presses, while its 240mm resolution meets ISO 13855 requirements for finger/hand protection in tight installations where standard light curtains cannot fit.

4. ​Product Advantages and Functional Benefits​

• ​Space Optimization: 215mm height enables guarding in areas with ≤250mm clearance
• ​Installation Flexibility: Kinematic mount absorbs ±15° misalignment without recalibration
• ​Advanced Logic: T11 controller supports:
  • ​Material Muting: 4-sensor sequences for automated part transfer
  • ​Floating Blanking: Dynamic beam deactivation around fixed obstructions
  • ​Cascade Mode: Synchronization with adjacent light curtains
• ​Enhanced Diagnostics: Continuous monitoring of beam alignment (±0.3°), intensity, and voltage
• ​High Immunity: Dual-wavelength IR beams resist welding arcs and sunlight interference
• ​Reduced Wiring: M12 connectors enable plug-and-play installation (60% faster than terminal boxes)
• ​Maintenance Alerts: Optical contamination detection triggers pre-failure warnings
• ​Global Compliance: Pre-validated to ISO 13855 safety distance standards
• ​Vibration Resistance: Maintains alignment in high-shock environments (30g IK08)

5. ​Core Functionality and Safety Operation​

The system operates via synchronized 950nm infrared beams between emitter and receiver. Kinematic prismatic joints maintain optical alignment despite angular deviations up to 15°. When beams are interrupted for >30ms, the T11 controller opens OSSD outputs within 20ms, triggering machine stop via safety PLCs. Continuous diagnostics monitor:

• Beam transmission integrity
• Synchronization stability
• Output circuit continuity (1kHz pulse testing)
• Voltage dips/overvoltage conditions
  The floating blanking function dynamically deactivates beams obscured by fixed fixtures while maintaining adjacent protection zones. Muting sequences allow temporary suspension via external sensors during automated material transfer. Safety reset requires deliberate confirmation after fault resolution. The 240mm beam spacing provides EN ISO 13855-compliant finger protection when installed at calculated safety distances based on machine stopping performance (formula: S = K × T + C).
