Gear Tooth Speed Sensors
GS101201 – GS101202 Sensors
Flange mount gear tooth speed sensor
Description
The GS101201-GS101202 series gear tooth speed sensors are Hall Effect devices designed for use in applications where ferrous
edge detection/near zero speed sensing is needed. They provide a sinking output current.
Features
