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 models with varying optical axis pitches (20mm and 40mm) and sensing heights (120mm to 940mm), minimizing unsensing areas with its 20mm pitch option. Featuring high-brightness LEDs for easy recognition from multiple angles and distances, this sensor includes essential functions like self-diagnosis, mutual interference prevention, and external diagnosis. Its robust IP65 protection structure ensures reliability in demanding industrial environments.

Functions & Features

• Self-diagnosis: Emitter/Receiver monitoring, direct light monitoring, over current monitoring. Control output turns OFF upon error, indicated by the operation indicator.
• Interference Protection: Master/Slave function to prevent sensing errors when multiple sensors are used in parallel.
• External Diagnosis: Emitting stops when TEST input (black wire) is 0V, allowing external systems to check sensor operation.
• Minimizes Unsensing Area: Achieved with a 20mm optical axis pitch (BW20- models).
• High Brightness LED: Emitter and Receiver LEDs ensure easy recognition from side, front, and long distances.

Troubleshooting

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
