SE61E is Banner Engineering’s ECONO-BEAM emitter for SE61 through-beam photoelectric sensing, delivering a 1.8 m (1800 mm) sensing range when powered by 10–30 V DC. As the emitter side of a through-beam pair, it provides no output and is paired with a separate receiver; the standard configuration includes a 2 m (6.5 ft) cable, with SE61E W/30 offering a 9 m (30 ft) cable. The sensing beam is infrared at 880 nm, and this model corresponds to the SE61 DC-series emitter (10–30 V DC, 1.8 m range).
