Transmissive Photosensors (Photo lnterrupters)
CNA1012K (ON1114)
Photo lnterrupter
For contactless SW, object detection
Unit: mm
■ Overview
CNA1012K 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 ele-
ment. 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
www.DataSheetth4iUck.cpolmate detection
• Fast response: tr , tf = 6 µs (typ.)
• Small output current variation against change in temperature
• Large output current
■ Absolute Maximum Ratings Ta = 25°C
