Product Overview

The D-44 BW Series Area Sensor is a through-beam type photoelectric sensor designed for long-distance detection up to 7m. It offers a wide range of models with varying optical axis pitches (20mm or 40mm) and sensing heights from 120mm to 940mm, minimizing unsensing areas. Featuring high-brightness LEDs for easy visibility from multiple angles and distances, this sensor includes self-diagnosis, mutual interference prevention, and external diagnosis functions. Its robust construction with IP65 protection ensures reliable operation in industrial environments. Ideal for applications requiring precise detection over extended ranges.

Technical Specifications

Ordering Information

Features

• Long sensing distance up to 7m.
• 22 types of products available (optical axis: 20/40mm, sensing height: 120 to 940mm).
• Minimizes unsensing area with 20mm optical axis pitch (BW20- models).
• High brightness LED on Emitter and Receiver for easy recognition from side, front, and long-distance.
• Includes self-diagnosis function, mutual interference prevention function, and external diagnosis function.

Functionality & Operation

• Operation Mode: Light ON fixed.
• Self-Diagnosis: Emitter/Receiver monitoring, direct light monitoring, over current monitoring. Operation indicator displays diagnosis status.
• Interference Protection: Master/Slave function to prevent sensing errors when using multiple sensors.
• External Diagnosis: TEST input (black wire) on emitter stops emitting, indicated by a flashing red LED, allowing external system confirmation of sensor operation.

Wiring & Connections

• Power Supply: 12-24VDC 10%.
• Output: NPN or PNP open collector output (max. 30VDC, max. 100mA).
• Connections: M12 connector (4-pin). Wiring details for Emitter and Receiver provided, including power, SYNC, 0V, and TEST/OUT.
• Connecting Cables: Sold separately (CID4-xT for Emitter, CID4-xR for Receiver, available in lengths 3m to 15m).

Safety & Usage Considerations

• Read "Safety Considerations" in the instruction manual before use.
• Power supply should be insulated and limited voltage/current or Class 2, SELV.
• Allow 1 second after power supply before use. Supply power to sensor first if using separate power supplies.
• For switching mode power supplies, ground F.G. terminal and connect a condenser between 0V and F.G. terminal.
• Use diodes or varistors to remove surge when connecting inductive loads like DC relays.
• Keep wires short and away from high voltage/power lines to prevent surge and inductive noise.
• Suitable for indoor use (within rated environment conditions), altitude max. 2,000m, pollution degree 2, installation category II.

Interference Prevention

When installing more than 2 sets of sensors, interference may occur. Install sensors with opposite transmission directions, use baffles between sets, or maintain adequate installation distances (Sensing distance (L) vs. Installation allowable distance (D) provided). Utilize the interference protection function (Master/Slave setup).
