Photo Interrupters

For contactless SW, object detection

Overview

CNZ1102 and CNZ1108 are 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

• Position detection accuracy : 1.2 mm

• Large output current

• Fast response : tr, tf = 4 µs (typ.) (CNZ1102)

6 µs (typ.) (CNZ1108)

• Small output current variation against change in temperature

• Small package used for saving mounting space (CNZ1108)
