Leuze electronic Retro-Reflective Sensor (AS-i)

 

Model: IPRK 18/A L.4

Part Number: 50030077

---

1. General Description

 

The Leuze IPRK 18/A L.4 is a retro-reflective photoelectric sensor designed for integration into AS-Interface (Actuator Sensor Interface) networks. It requires a reflector to operate.

Unlike standard sensors that wire directly to a PLC input card, this sensor connects to the yellow AS-i bus cable. It features a polarization filter, allowing it to reliably detect shiny or reflective objects (like shrink-wrapped pallets or metal cans) without false triggering.

Key Features 🎯

 

• AS-Interface Integrated: Directly connects to the AS-i bus system, reducing wiring complexity.

• Polarized Retro-Reflective: Detects shiny objects reliably using a polarization filter.

• Visible Red Light: Uses a bright LED light source for easy alignment with the reflector.

• Sensitivity Adjustment: Features a potentiometer for fine-tuning the sensing range.

• Robust Housing: Standard 18-series rectangular housing with metal M12 connector.
