This Banner SM31ELQD photoelectric sensor has a M18 threaded-mount housing and emits an infrared LED sensing beam with an 880 nm wavelength and a range of up to 30 m. The opposed-mode emitter accepts 10-30 VDC input through its 4-Pin Euro-style quick-disconnect (QD) connector and is intended for use with a Euro-style QD cordset (not included). The thermoplastic housing is durable and the sensor has an operating temperature range of -20 to +70 degrees C. It meets the Ingress Protection (IP) 67 standard for protection from water and dust and is Underwriters Laboratories Recognized (UR), Canadian Standards Association (CSA) certified, and European Conformity (CE) compliant for quality assurance. This opposed-mode emitter is suitable for use in automation applications such as in manufacturing and packaging in a wet environment.Banner engineering manufactures and distributes photo eyes, sensors, safety switches, and other related products for industrial and process automation. The company, founded in 1966, is headquartered in Minneapolis, MN.
