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

• Highly precise position detection: 0.3 mm

• Wide gap between emitting and detecting elements, suitable for thick plate detection

• Fast response: tr , tf = 6 µs typ.

• Small output current variation against change in temperature

• Large output current
