Photo Interrupter

For contactless SW, object detection

Outline

ON1110 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

• Fast response : tr, tf = 6 µs (typ.)

• Small output current variation against change in temperature

• Small package used for saving mounting space
