Banner Engineering Q20E-W30 Photoelectric Sensor

The Banner Engineering Q20E-W30 is a World-Beam Q20 Series emitter (red) for through-beam sensing, delivering a 12 m detection range when paired with a compatible Q20 receiver. It emits a 624 nm visible red beam and operates on 10–30 V DC with no output, making it the active emitter in a two-part through-beam system. The W/30 designation confirms a 9 m (30 ft) cable length, enabling flexible mounting distances in demanding environments. Built for rugged industrial use, the device carries an IP67 rating and a rectangular housing designed for dependable installations in harsh conditions. In typical applications, it serves as the emitter in conveyor and part-detection setups, where a matching Q20 receiver completes the sensing loop to alert downstream equipment or control systems of object presence or absence.
