Overview
The Banner Q20E-78017 is a compact, rugged photoelectric emitter sensor engineered for industrial automation and material handling applications. Part of Banner’s WORLD-BEAM Q20 series, this sensor delivers precise through-beam detection with a 12-meter sensing range. The Q20E-78017 operates on 10-30VDC power and is housed in a sealed, thermoplastic enclosure designed to withstand harsh factory environments.
