E3S-C is a built-in amplifier photoelectric sensor with a metal housing that is water- and oil-resistive. It has a sensing distance six times longer than OMRON's conventional photoelectric sensors, ensuring stable detection of objects. It has a vibration resistance of 10 Hz to 2 kHz and a shock resistance of 1,000 m/s2 (approximately 100G). It incorporates an NPN and PNP output selector, reducing the stock of photoelectric sensors. It also has a fuzzy mutual interference prevention function. The E3S-C's optical axis coincides with its mechanical axis, ensuring easy axis adjustment.
The E3S‑C is a water‑ and oil‑resistive photoelectric sensor with a metal housing, offering long sensing distances (up to 30 m for through‑beam models) and IP67/NEMA 6P enclosure ratings. It features selectable NPN or PNP open‑collector outputs, Light‑ON/Dark‑ON modes, and vibration resistance up to 2 kHz.
The manual includes ordering information, detailed specifications, wiring and mounting instructions, a conversion table for legacy E3S models, and dimensional drawings. It also describes output circuit operation and environmental limits such as temperature, humidity, and shock resistance.
