This Eaton 1451E-6547 Enhanced 50-series photoelectric sensor has a visible red LED sensing beam with a 660 nm wavelength and a range of up to 16'. The polarized-retroreflective mode sensor accepts 10-40 VDC input through its 4-pin micro DC-style quick-disconnect (QD) connector and is intended for use with a mating 4-pin micro DC-style QD cable (not included). It has 250 mA bipolar (NPN/PNP) output. The sensor has an adjustable gain setting screw, a light/dark operate selector switch, and three status-indicator LEDs. Its threaded-mount fiberglass-reinforced plastic housing is durable and the sensor has an operating temperature range of -25 to +55 degrees C. It meets the Ingress Protection (IP) 69K standard for protection from water under pressure and dust and is Underwriters Laboratories Listed (UL) and Canadian Standards Association (CSA) certified for quality assurance. This polarized-retroreflective mode sensor is suitable for use in automation applications such as in manufacturing and packaging in a wash down environment.Eaton manufactures electrical, hydraulic, and mechanical power equipment.
