Banner Engineering Corporation Q45BW22DQ24MDC Relay

The Banner Engineering Q45BW22DQ24MDC Relay is a Q45 Series rugged rectangular infrared diffuse photoelectric sensor with a SPST solid-state relay output. It detects objects at up to 450 mm (18 in) in diffuse mode and is powered from 90–250 VAC, with the 24MDC variant wired via a five-pin Micro Integral QD connector for fast, reliable installation. The IP67-rated thermoplastic housing provides strong protection in harsh environments, and the output is a short-circuit/overload protected FET solid-state relay designed for AC switching. Indicator LEDs include a green power LED and a red AID system LED that signals when the sensor sees its modulated light source. The 24MDC variant specifies the five-pin Micro Integral QD wiring, while the broader Q45BW22DQ family shares the same diffuse sensing and 450 mm range. Electrical characteristics include an average current draw around 20 mA, with a peak output current of 500 mA at 120 VAC and 750 mA at 250 VAC, making it suitable for integration into industrial automation tasks that require reliable diffuse detection and AC switching in demanding environments.
