Technical Performance & Data Sheet

Deterministic Industrial Fieldbus & System Integration

The optical monitoring assembly interfaces across industrial networks using Profinet and EtherNet/IP deterministic protocols. Internal timing routines maintain real-time response speed to preserve safety loop integrity across programmable safety controllers, while optimized firmware flash compatibility prevents signal transmission delays during high I/O density scaling events.

Field Alignment & Physical Wiring Directives

Structural Mounting & Alignment Setup

• Position the emitter and receiver units strictly parallel across the 0.2 to 7 m operational range.
• Fasten all mounting brackets directly to rigid structural steel to eliminate mechanical vibration drift.
• Verify vertical optical axis alignment across all 22 beams before locking the mounting hardware in place.

Power Connections & EMI Mitigation

• Power the optical heads using an isolated SELV/PELV 24 VDC power supply maintaining ripple below 10% max.
• Route sensor signal cabling through dedicated metallic conduits away from variable frequency drive outputs.
• Connect the extruded aluminum housing directly to protective earth (PE) using a low-impedance ground conductor.

Diagnostic Engineering & Operating Queries

• Q: What power supply voltage parameters are required to maintain internal logic operation?

  A: The SELV/PELV source must maintain 24 VDC within a +/-20% voltage window, keeping peak-to-peak ripple restricted below 10% max to prevent internal logic resets.

• Q: Can cable quick-disconnect plugs be detached while 24 VDC power is applied?

  A: No, live disconnection is strictly prohibited. Always de-energize the main 24 VDC supply rail prior to servicing field wiring to prevent output transistor degradation.

• Q: What object size threshold causes an immediate beam disruption trigger?

  A: Configured with a 20 mm beam gap across 22 beams, the optical array senses any opaque target measuring 25-mm diameter or greater for hand and arm detection.

• Q: How do the PNP sourcing outputs switch state under clear optical conditions?

  A: When no optical interruption exists, the PNP output transistors drive the signal lines active high, delivering 24 VDC directly to the safety relay inputs.

• Q: What is the maximum current draw of the 22-beam emitter and receiver heads?

  A: Under no-load conditions, the 22-beam emitter head draws up to 52 mA max, while the matching receiver head draws up to 45 mA max from the 24 VDC supply.

• Q: What ingress protection rating applies to the metal housing assembly?

  A: The aluminum housing complies with IP65 enclosure standards, preventing dust ingress and protecting optical components against low-pressure water jets from any angle.

• Q: What emission wavelength is generated by the transmitter LED array?

  A: The transmitter head incorporates solid-state infrared LEDs emitting at a peak wavelength of 870 nm to synchronize with the receiver optical sensor array.

• Q: How can noise disruption be mitigated in high-interference industrial settings?

  A: Run shielded cables through grounded metallic conduit and terminate the cable drain wire to protective earth ground at a single cabinet interface location.
