Gear Tooth Speed Sensors  GS101205 Sensors
Gear Tooth Speed Sensors
GS101205 Sensors
Flange mount gear tooth speed sensor rated to 140 °C
Description
The GS101205 series gear tooth speed sensors are Hall Effect devices designed for use in applications where ferrous edge
detection/near zero speed sensing is needed. The single Hall design is immune to alignment issues allowing unlimited mounting
positions. They provide a sinking current output.

Note: An external pull-up resistor is required, the value of which is dependent on the supply voltage. The resistor should be
connected between the output and Vcc. Refer to the wiring diagram for lead colors or pin numbering as applicable.

Installation
For best results, we recommend targets made from low carbon cold rolled
steel. Other factors that influence sensor performance include gear tooth
height and width, space between the teeth, shape of the teeth and thickness
of the target. As a general guideline, consider a target with minimum
parameters as shown below. Note that smaller dimensions may work, but
testing for the application is required.
