Description
The E3S-GS3E4 Grooved-type Photoelectric Sensor is a compact, built-in amplifier sensor designed for simple object detection in slot or groove applications where precise optical axis alignment is difficult or unnecessary. Its grooved sensing structure inherently guides the target through a fixed slot, eliminating the need for traditional emitter-receiver alignment and simplifying installation. With a 30 mm slot sensing distance and both NPN and PNP output options, the E3S-GS3E4 is suitable for presence/absence detection of small parts, sheets, tags, and other interrupters on conveyors or in fixtures. It supports rugged industrial performance with IP67 protection, fast response, and robust mechanical design.
