GS101205

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.

The resistor should be connected between the output and Vcc. Refer to the wiring diagram for lead colors or pin numbering as applicable.

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.
