Omron E3S-A Photo Sensor

Core Performance & Industrial Application

The Omron E3S-AD32 (posted as E3S-A32) is a medium-size built-in-amplifier diffuse-reflective photoelectric sensor, infrared LED (850 nm), sensing distance up to 700 mm on 100×100 mm white paper.

PNP open-collector output, 100 mA max load at 30 VDC; Light-ON/Dark-ON selectable; 35 mA max current consumption; pre-wired 2 m cable.

IP67 / NEMA 4X (indoor); PBT case; compact horizontal body for conveyor and presence detection.

It detects object presence/absence without reflector in packaging and material-handling lines.
