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. High-brightness LEDs on both the emitter and receiver ensure easy recognition from side, front, and long distances. The sensor includes self-diagnosis, mutual interference prevention, and external diagnosis functions, along with an IP65 protection structure.

Wiring and Connections

Input/Output Circuit and Connections:

• NPN open collector output
• PNP open collector output
• Operation indicator (LEDs for POWER, Stable light ON, Unstable, Red for TEST/M/S)
• Connecting Cable (sold separately, M12 connector)
• Wiring Connection details provided for Emitter and Receiver pins.
• Connections for TEST input: When TEST input (black) of emitter is 0V, emitting stops.
• MASTER/SLAVE connections: Connect 'TEST (M/S)' of SLAVE emitter to 'SYNC' of MASTER.

Installation and Usage

• Function: Self-diagnosis, Interference protection.
• Installation: Emitter and receiver should be installed in the same up/down direction. Avoid installation where light reflected from wall surfaces can cause issues. Check normal operation with a sensing target before use (Interval distance: min. 0.5m).
• Interference Prevention: For parallel installation of multiple sensors, use the master/slave function to avoid sensing errors due to light interference. Transmission direction should be opposite between 2 sets. Baffles and installation out of interference distance are recommended.
• Proper Usage Guidelines: Follow instructions, use insulated and limited voltage/current power supply (Class 2, SELV), wait 1 sec after power supply, ground F.G. terminal for switching mode power supply, remove surge for inductive loads, keep wires short and away from high voltage lines.
• Environmental Conditions: Suitable for indoor use (within rated environment conditions), altitude max. 2,000m, pollution degree 2, installation category II.
