Omron E3S-AD87 Photoelectric Sensor

The Omron E3S-AD87 Photoelectric Sensor is a non-contact object-detection switch that uses a light beam to sense presence, position, or motion in automated systems. Depending on model variant, it supports diffuse, retro-reflective, or through-beam sensing, with a sensing range that is model dependent, and it uses a LED emitter as the light source. It offers NPN or PNP discrete outputs (variant dependent) and runs on 12–24 V DC, delivering fast switching for dynamic detection. LED indicators provide at-a-glance power and output status, and the rugged industrial enclosure carries an IP65 rating for use in harsh manufacturing environments. Mounting options include bracket or surface mount, and the unit is designed for industrial temperature ranges. Typical applications include conveyor systems, packaging machinery, assembly lines, material handling equipment, and inspection stations to detect product presence, position, and motion, making it a common replacement or retrofit choice for Omron systems and other automation setups.
