The E3SGS3E4 is a grooved head photoelectric sensor with a built-in DC amplifier, designed for general-purpose applications like detecting edges, labels, and marks. It features a 3 cm sensing distance and operates on a 12 to 24 VDC power supply. The sensor provides an NPN solid-state output with a maximum load of 80 mA and has a fast response time of 1 ms. Housed in a durable metal enclosure with an IP67 rating, it uses an infrared LED light source and includes light and stability indicators for easy sensitivity adjustment. Its ability to detect opaque and translucent objects makes it suitable for various industrial automation tasks.
