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. Features Typical Applications From near zero speed up to 15 kHz sensing capability Speedometers Plastic flange mount-housing Anti-lock braking systems Resistant to fuels, solvents, and lubricants associated with Exercise equipment engines, transmissions, brakes and chassis systems CNC machine tools 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** -40 C to 140 C (-40 F to 284 F) **up to 150 C (302 F) with reduced performance Storage Temperature -40 C to 150 C (-40 F to 302 F) Ingress Protection IP67 Electrical Specifications Operating Supply Voltage 5 to 24 VDC Maximum Input Voltage 30 VDC Maximum Reverse Voltage 26.5 VDC Supply Current 3 mA typ., 6 mA max Output Sink Current 25 mA max Recommended Pull-Up Resistor See chart Mechanical Specifications Housing Material Glass Reinforced Thermoplastic 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 Possible O-ring size AS568A-016 (varies with application) Products Part Number Leads Connector** GS101205 Delphi Metri-Pack 150 **Mates to Delphi connector 12162280 www.cherryswitches.com Page 1 of 2, Last saved by 2014-10-29, 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.
