PS226-Z11-R200 Mechanical Interlock Single Contact Switch IP67 Aluminum Industrial Guard

1. Product Overview​

The Schmersal PS226-Z11-R200 represents a high-performance Type 4 safety light curtain engineered for precision machine safeguarding in demanding industrial environments. Featuring a ​226mm detection height​ with ​200mm resolution beams​ (R200 suffix), this system employs ​kinematic beam alignment technology​ (±15° angular tolerance) to maintain protection field integrity despite installation misalignment or thermal drift. The integrated ​Z11 advanced safety controller​ provides sophisticated logic capabilities including cascading synchronization, dynamic floating blanking, and configurable muting sequences. Encased in rugged ​UV-stabilized polycarbonate housing (IP66 rated)​, the unit withstands extreme conditions like high-pressure washdowns (IP69K optional), metal dust, cutting fluids, and mechanical impacts. Synchronization via industrial-grade cable or optional 2.4GHz RF modules ensures reliable operation across distances up to ​25m.

​2. Key Technical Parameters​
Certified to IEC 61496-1/2 Type 4, ISO 13849-1 PL e (Category 4), and IEC 62061 SIL 3 safety standards, the system delivers ≤20ms response time from beam interruption to safety shutdown. Operating voltage spans 24V DC ±20% with ≤5W power consumption. Dual PNP OSSD outputs (100mA @ 24V DC) interface directly with safety PLCs, while auxiliary outputs provide diagnostic signaling. Environmental resilience includes operation from -15°C to +55°C, 40,000 lux ambient light immunity, and 30g shock resistance (IEC 60068-2-27). Continuous self-monitoring covers 15+ parameters: beam intensity, synchronization integrity, inclination (±0.3°), and voltage stability. The kinematic system maintains optical alignment within 0.5° tolerance throughout its ±15° compensation range.

​3. Primary Applications and Use Cases​
This precision system excels in hazardous point-of-operation scenarios:

• ​CNC press brakes: Finger protection during angled bending operations
• ​Robotic welding cells: Creating adaptive protection fields around complex tool paths
• ​Injection molding: Monitoring mold area with thermal drift compensation
• ​Automotive assembly: Guarding curved weld fixtures with piping obstructions
• ​Packaging machinery: Securing narrow conveyor transfers with blanked areas
• ​Forging operations: Maintaining alignment in high-vibration environments
• ​Microelectronics: Protecting delicate component assembly stations
• ​Pharmaceutical filling: Guarding vial handling systems with cleanroom compatibility
  The 200mm resolution specifically targets finger/hand protection per EN ISO 13855 where traditional 300mm+ curtains are unsuitable. Kinematic compensation prevents alignment failures in applications experiencing machinery settling or thermal deformation up to ±15°.

​4. Product Advantages and Functional Benefits​

• ​Installation Resilience: Kinematic mounts eliminate alignment adjustments during thermal drift (±15° tolerance)
• ​Advanced Safety Logic: Z11 controller enables cascade networking (≤4 units), floating blanking, and 4-sensor muting sequences
• ​Predictive Diagnostics: Beam degradation alerts via auxiliary outputs before safety function compromise
• ​Operational Efficiency: Dynamic floating blanking maintains protection while accommodating fixtures
• ​Durability: Impact-resistant housing withstands 50J impacts (IK10) in high-traffic areas
• ​Cost Optimization: Reduces commissioning time by 60% versus conventional light curtains
• ​Flexible Integration: RF synchronization option enables retrofits in cable-restricted environments
• ​Compliance Assurance: Pre-validated safety templates for ISO 13855 and ANSI RIA R15.08
• ​Maintenance Reduction: Sealed optical chambers resist particulate accumulation in foundry/metalworking settings

​5. Core Functionality and Safety Architecture​
Operational integrity relies on redundant microprocessor architecture:

1. ​Infrared Monitoring: Dual-wavelength (850/950nm) pulsed beams create interference-resistant protection fields
2. ​Continuous Validation: Synchronization signals verified every 5ms with <1µs timing accuracy
3. ​Safety Response: Beam interruption >30ms triggers OSSD shutdown within 20ms (Cat. 4 stop)
4. ​Smart Blanking: Dynamic beam deactivation maintains adjacent zone protection around permanent obstructions
5. ​Failsafe Design: Voltage dips ≤15ms or synchronization loss <5ms triggers protective stop
6. ​Recovery Protocol: Manual reset required after faults, with logged diagnostics accessible via AUX outputs
   The 200mm beam spacing enables safety distance calculation per ISO 13855 (S = 2000 × T + 80mm). When cascaded with other units, encrypted synchronization ensures field continuity without dead zones. RF variants maintain <1ms timing accuracy through 20cm steel obstructions via AES-128 encrypted signals.
