Transmissive Photosensors (Photo lnterrupters)
CNA1012K
Photo lnterrupter
For contactless SW, object detection
■ Overview
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
■ Absolute Maximum Ratings T
■ Electrical-Optical Characteristics T
Note) 1. Input and output are practiced by electricity.
Publication date: April 2004
• Highly precise position detection: 0.3 mm
• Wide gap between emitting and detecting elements, suitable for
• Fast response: t
• Small output current variation against change in temperature
• Large output current
