PS116-Z12R-L200-K210 Dual Contact Mechanical Interlock Switch IP67 Aluminum 2.1M Cycle Industrial Guard

1. Product Overview​

The Schmersal PS116-Z12R-L200-K210 is a high-density Type 4 safety light curtain engineered for precision machine guarding in space-critical automation environments. Featuring an ​ultra-compact 116mm protection height​ with ​200mm resolution beams (L200 suffix)​, this system delivers industry-leading finger/hand protection per ISO 13855 standards. The "K210" designation incorporates ​kinematic beam alignment technology​ with ±15° vertical compensation to mitigate misalignment from thermal drift, vibration, or installation tolerances. Integrated "Z12R" controller provides advanced safety logic including cascading, dynamic floating blanking, and Safe Torque Off (STO) readiness. Housed in ​IP67-rated polycarbonate housing​ (IP69K optional), it withstands harsh industrial conditions like high-pressure washdowns and metal particulate exposure. Synchronization via M12 connectors or optional RF modules supports ranges up to 15m.

​3. Primary Applications and Use Cases​

This system excels in micro-automation scenarios requiring maximum space efficiency:

• ​Semiconductor fabrication: Guarding wafer handling robots and wire bonding machines in cleanrooms
• ​Medical device assembly: Protecting automated syringe filling lines with <200mm clearance
• ​Micro-electronics: Securing SMT pick-and-place equipment during PCB component placement
• ​Precision machining: Monitoring 5-axis micromilling tool changes with vibration compensation
• ​Pharmaceutical packaging: Enabling safe access to blister sealing stations with irregular fixtures
• ​Collaborative robotics: Creating adaptive safety zones around miniaturized cobot workcells
• ​Laboratory automation: Perimeter guarding for automated microscopes and DNA sequencers
  The K210 kinematic technology uniquely prevents misalignment failures in applications like injection molding (thermal expansion) or automated conveyors (settling/vibration).

​4. Product Advantages and Functional Benefits​

• ​Space Optimization: 116mm profile fits installations impossible for standard light curtains (e.g., tight clearances <150mm)
• ​Kinematic Precision: ±15° auto-alignment eliminates manual recalibration, reducing maintenance downtime by 60%
• ​Safety Integration: Z12R controller enables direct STO output configuration for servo drives without additional relays
• ​Diagnostic Depth: Real-time beam intensity monitoring predicts optical fouling before safety degradation
• ​Flexible Networking: Cascade mode synchronizes ≤4 units for extended protection fields
• ​Adaptive Guarding: Floating blanking maintains 200μm alignment while avoiding fixed obstructions
• ​Compliance Assurance: Pre-validated to ISO 13855 and ANSI B11.19 safety distance standards
• ​Harsh Environment Durability: IP67 sealing withstands cutting fluid immersion (IEC 60529)
• ​Installation Efficiency: Tool-less beam alignment system cuts commissioning time by 45%
• ​Global Certification: CE, UL, and CRN approvals for worldwide deployment.

​5. Core Functionality and Safety Architecture​

The system employs ​triple-redundant monitoring architecture:

1. ​Synchronized Beam Transmission: Dual-wavelength IR pulses (850/950nm) between emitter/receiver with <1µs timing tolerance
2. ​Dynamic Kinematic Compensation: Spring-loaded prismatic joints maintain perpendicular optical paths despite ±15° deflection
3. ​Safety Response Protocol:
   • Beam interruption >30ms triggers OSSD shutdown within 18ms
   • STO-ready outputs de-energize drives in ≤100ms (IEC 61800-5-2 compliant)
4. ​Continuous Diagnostics:
   • Real-time inclination tracking via MEMS sensors
   • Encryption-secured synchronization (AES-128 for RF variants)
   • Cyclic OSSD pulse testing (2kHz) detecting wiring faults
5. ​Smart Blanking Logic: Temporarily deactivates ≤4 beams around fixtures without compromising adjacent zones
6. ​Failure Management:
   • Stores 32+ error codes with timestamps (e.g., E45: Beam 2 synchronization loss)
   • Forces manual reset after faults per ISO 13849 fail-safe principles
     Safety distances calculated per ISO 13855 formula S = 2000 × T + 120mm ensure hazardous motion stops before finger access. RF synchronization maintains <1ms latency through 150mm steel obstructions.
