PHOTOHEAD PH16B / PH21

PHOTOHEAD PH16B / PH21

Overview

The Photohead photoelectrically detects the web edge.

As a pulsed infrared light emitting diode (LED) is used as the light source, the Photohead can be applied for a web such as photosensitive paper, which is adversely affected by light.
The Photohead PH21 photoelectrically detects the web edge.
This sensor is a miniaturized model of PH16B, but with the same functions.
