CAM Sensor Rotary Type 1

Rotary Sensor Type 1: 25mm/36mm/50mm

This rotary sensors have 25/36/50mm diameter and measures absolute the angle of a target. Used in conjunction with a CTU chip, the system reports full absolute angular position over 360°.

A single CAM204 Central Tracking Unit (CTU) chip can operate up to 4 Type 1 sensors, including a mix of linear and rotary.

Features

• Simple non-contact target
