Product Overview

The D-44 BW Series Area Sensor is a through-beam type photoelectric sensor designed for long-distance 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-) minimizes unsensing areas, ensuring comprehensive coverage. High-brightness LEDs on both the emitter and receiver provide easy recognition from side, front, and long distances. The sensor includes essential functions such as self-diagnosis, mutual interference prevention, and external diagnosis for reliable operation. Its robust construction is rated IP65 according to IEC standards, making it suitable for demanding industrial environments.

Safety and Usage Precautions

• Read Safety Considerations in the instruction manual before use.
• Use 12-24VDC power supply that is insulated and limited voltage/current or Class 2, SELV.
• Wait 1 sec after supplying power before using the product. Supply power to the sensor first if using separate power supplies for sensor and load.
• For switching mode power supplies, ground F.G. terminal and connect a condenser between 0V and F.G. terminal to remove noise.
• For DC relays or other inductive loads, remove surge using diodes or varistors.
• Wire as short as possible and keep away from high voltage lines or power lines to prevent surge and inductive noise.
• Suitable for indoor use within rated environmental conditions, altitude max. 2,000m, pollution degree 2, installation category II.
