Gear Tooth Speed Sensors GS1001 – GS1002 Sensors Hall Effect gear tooth speed sensor with adjustable stainless steel housing Description The GS1001-GS1002 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. Features Typical Applications • From near zero speed up to 15 kHz sensing capability • Speedometers • 10 bit dynamic threshold direction offers: • Anti-lock braking systems -Automatically adjusting magnetic range • Exercise equipment -Self-compensating to target geometry • CNC machine tools • Compatible with unregulated power supply • RoHS compliant • IP67 • Typical air gap of 1.5 mm* Environmental Specifications Vibration Sinusoidal, 15 g max from 40 Hz to 2 kHz Mechanical Shock Resistance 50 g Maximum Speed Detection 15 kHz Operating Temperature (GS100101, GS100201) -40 °C to 105 ⁰C (-40 ⁰F to 221 ⁰F) Operating Temperature (GS100102, GS100202) -40 °C to 125 ⁰C (-40 ⁰F to 257 ⁰F) Storage Temperature -40 °C to 125 ⁰C (-40 ⁰F to 257 ⁰F) Ingress Protection IP67 Electrical Specifications Operating Supply Voltage 5 to 24 VDC Maximum Input Voltage 30 VDC Maximum Reverse Voltage 24 VDC Supply Current 3 mA typ., 6 mA max Output Sink Current 20 mA max Recommended Pull-Up Resistor See chart Mechanical Specifications Housing Material 303 Stainless Steel Maximum Installation Torque Limit 5.65 Nm (50 in lb) on threads Operating Air Gap / Sensing Distance* 1.5 mm (0.06") *With recommended target type; see drawing Sensor Orientation Not sensitive Products Part Number Thread Shielded Cable with Drain Connector GS100101 M12-1 12 mm, 4-pin circular mating connector, type IEC 60947-5-2 GS100102 M12-1 22 AWG x 1 m GS100201 M18-1 12 mm, 4-pin circular mating connector, type IEC 60947-5-2 GS100202 M18-1 22 AWG x 1 m www.cherryswitches.com Page 1 of 2, Last update 2015-12-15, Specifications subject to change without notice.

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.

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.
