D-44 BW Series Area Sensor
Product Overview
The D-44 BW Series Area Sensor is a high-performance through-beam type sensor designed for long-range detection up to 7 meters. It offers a wide range of configurations with 22 product types, featuring optical axis pitches of 20mm or 40mm and sensing heights from 120mm to 940mm. The 20mm optical axis pitch (BW20- models) minimizes unsensing areas, ensuring comprehensive coverage. High-brightness LEDs on both the emitter and receiver provide easy recognition from side, front, and long distances. This sensor incorporates essential functions such as self-diagnosis, mutual interference prevention, and external diagnosis, along with an IP65 protection structure for robust operation in industrial environments. It is suitable for applications requiring reliable detection of opaque objects.

Troubleshooting
Operation Indicator Troubleshooting: A table maps indicator states to potential causes and troubleshooting steps.
General Troubleshooting:
- Not operating: Check power supply, cable connections, and ensure operation within rated sensing distance.
- Not operating sometimes: Clean sensor cover, check connector connections.
- Control output is OFF even though there is no target object: Verify sensing distance, check for obstacles blocking light, and ensure no strong electric waves or noise interference.
- LED displays for specific errors (e.g., break of light emitting element, emitter failure, receiver failure, synchronous line issues, control output overcurrent, emitter malfunction): Refer to indicator status and consult the manual or contact Autonics Corp.
Proper Usage
- Follow instructions in 'Proper Usage'.
- Use 12-24VDC power supply that is insulated and limited voltage/current or Class 2, SELV.
- Wait 1 second after supplying power before use. Supply power to the 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 to remove noise.
- When connecting inductive loads like DC relays, remove surge using diodes or varistors.
- Keep wiring short and away from high voltage or power lines to prevent surge and inductive noise.
- Suitable for indoor use (within specified environmental conditions), altitude max. 2,000m, pollution degree 2, and installation category II.
