The Banner Engineering Q20EW is a through-beam emitter in the rugged Q20 Series, designed to pair with a Q20 receiver for long-range photoelectric sensing in industrial lines. The emitter operates from 10 to 30 V DC, provides no local output, and the Q20EW/30 variant includes a 9 m (30 ft) cable for easy integration with the companion receiver. When used as a through-beam pair, the system can achieve up to 12 m of sensing distance, housed in an IP67-rated, rugged, overmolded plastic enclosure with 25.4 mm mounting hole spacing; a visible red alignment LED aids setup and alignment.
