Product Description

​The Omron E3A2-10M4D is a through-beam photoelectric sensor with an integrated timer, offering a sensing distance of up to 10 meters. It utilizes a pulse-modulated infrared LED light source (950 nm) and provides independent ON- and OFF-delay timing functions adjustable from 0.1 to 5 seconds. The sensor operates on a supply voltage of 24 to 240 VAC or 12 to 240 VDC and features a relay output with a single-pole double-throw (SPDT) configuration, supporting loads up to 3 A at 250 VAC. Designed for industrial applications, it offers robust performance with an IP66-rated enclosure, ensuring protection against dust and water ingress. Please note that this model has been discontinued; however, alternatives such as the E3A2-10M4T or E3A2-10M4 are available.
