The Omron E32-T22S is a through-beam fiber optic sensor head designed for precision detection of extremely small parts. It uses a separate emitter and receiver pair, with a narrow view that concentrates the beam on a small target area. Key dimensions: sensing head length 15 mm, diameter 3 mm, with a standard 2 m cable (cut-to-length rated). The minimum sensing object is 0.1 mm diameter, making this head suitable for fine part presence or edge detection in confined spaces. Cable bending radius is specified as R10; maintain that radius during routing to avoid internal fiber damage.
Application Fit
This head mates to a compatible fiber amplifier (sold separately) and is typically used in electronics assembly, semiconductor handling, or automated inspection stations where the target is smaller than 0.1 mm or access is limited. The narrow view reduces false triggers from adjacent parts.
