Gear Tooth Speed Sensors
GS1005 – GS1007 Sensors
Hall Effect gear tooth speed sensor
with adjustable anodized aluminum housing
Description
The GS1005-GS1007 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 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.
