BW20-36P
Product Description
Product Overview
The D-44 BW Series Area Sensor is a high-performance through-beam type 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- models) minimizes unsensing areas. Equipped with 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 IP65 protection structure ensures reliable operation in demanding environments.

Proper Usage
- Follow instructions in 'Proper Usage'. Otherwise, it may cause unexpected accidents.
- 12-24VDC power supply should be insulated and limited voltage/current or Class 2, SELV power supply device.
- Use the product, 1 sec after supplying power. When using separate power supply for the sensor and load, supply power to sensor first.
- When using switching mode power supply to supply the power, ground F.G. terminal and connect a condenser between 0V and F.G. terminal to remove noise.
- When connecting a DC relay or other inductive load, remove surge by 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.
- This unit may be used in the following environments: Indoors (in the environment condition rated in 'Specifications') Altitude max. 2,000m Pollution degree 2 Installation category II
