Banner Engineering Q20E W 30 Photoelectric Sensor

The Banner Engineering Q20E W/30 is a World-BEAM Q20 Series emitter (red) photoelectric sensor designed specifically for through-beam systems, delivering up to 12 m (39.3 ft) of detection range with a 9 m (30 ft) cable; its compact rectangular thermoplastic housing is rugged and sealed for industrial environments. It operates from 10–30 V DC and, as an emitter, provides no output signal on its own—the receiver in the opposing unit completes the sensing circuit; this model is the emitter half of Banner's through-beam pairing. The device uses a visible red beam at 655 nm, includes indicator LEDs for alignment, and carries an IP67 rating with NEMA 4X protection to withstand harsh cleaners, dust, and immersion scenarios; it is part of Banner's Q20 Series designed for packaging, material handling, and conveying systems. The W/30 suffix denotes the 9 m PVC cable model, and Banner's literature confirms the Q20E W/30 as the emitter in an opposed through-beam arrangement within the Q20 Series, available across regions.
