Photo lnterrupter
For contactless SW, object detection
■ Overview
is a photocoupler in which a high efficiency GaAs infrared light emitting diode is used as the light emitting element, and a high sensitivity phototransistor is used as the light detecting element. The two elements are arranged so as to face each other, and objects passing between them are detected.
■ Features
• Wide gap between emitting and detecting elements, suitable for thick plate detection Gap: 10 mm
• Fast response: tr , tf = 6 µs typ.
• The external case is molded using visible light cutoff resin. The case has no openings, so the photosensor is not easily susceptible to output attenuation resulting from dust or particles
