Aromat MQ-W3A-DC12-24V Photoelectric Sensor

The Aromat MQ-W3A-DC12-24V is a triple-beam, retro-reflective photoelectric sensor with an integrated amplifier designed for precise short‑range detection on reflective surfaces. It operates from 12 to 24 V DC and delivers a rated sensing distance of 40 mm with an optimum setting range of 20–40 mm, ideal for small-part detection in compact automation layouts. In testing, it detects a 10 × 10 mm white non-glossy target at 40 mm, while the emitting element is an infrared LED and the enclosure is a die-cast zinc alloy. The sensor includes a 4-core cable, 2 m long, and supports extension up to 100 m with 0.3 mm² or larger cable; a mounting bracket is provided (1 set). Output is an NPN transistor (sinking) with selectable light-on or dark-on operation, accommodating common automation needs where precise edge or presence sensing is required. Weighing about 0.15 kg, the MQ-W3A-DC12-24V is a compact, robust choice for applications like conveyors, packaging lines, and other short‑range position sensing tasks. Note: this model is listed as discontinued by Panasonic as part of the MQ-W series.
