Product Description
The Omron E3S-GS1E4 is a grooved-type (fork/slot) photoelectric sensor with a built-in DC amplifier, designed for precision mark sensing on transparent film and similar applications. It features a 10mm (1 cm) slot/groove width, NPN solid-state output with wire-selectable Light-ON/Dark-ON operation, and dual LED indicators (red LIGHT and green STABILITY) for easy sensitivity adjustment. The sensor ships pre-wired with a 2-meter cable and is rated IP65 for protection against dust and water jets.
