Gear Tooth Speed Sensors GS101201 – GS101202 Sensors Flange mount gear tooth speed sensor Description The GS101201-GS101202 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 output current. Features       Typical Applications From near zero speed up to 15 kHz sensing capability Plastic flange-mount housing Compatible with unregulated power supply RoHS compliant IP67 Typical air gap of 1.5 mm*     Speedometers Anti-lock braking systems Exercise equipment CNC machine tools Environmental Specifications Vibration Mechanical Shock Resistance Maximum Speed Detection Operating Temperature Storage Temperature Ingress Protection Sinusoidal, 15 g max from 40 Hz to 2 kHz 50 g 15 kHz -40 ⁰C to 125 ⁰C (-40 ⁰F to 257 ⁰F) -40 ⁰C to 125 ⁰C (-40 ⁰F to 257 ⁰F) IP67 Electrical Specifications Operating Supply Voltage Maximum Input Voltage Maximum Reverse Voltage Supply Current Output Sink Current Recommended Pull-Up Resistor 5 to 24 VDC 30 VDC 24 VDC 3 mA typ., 6 mA max 20 mA max See chart Mechanical Specifications Housing Material Maximum Installation Torque Limit Operating Air Gap / Sensing Distance* * With recommended target type; see drawing Sensor Orientation Possible O-ring size Glass Reinforced Thermoplastic 5.65 Nm (50 in lb) on threads 1.5 mm (0.06") Not sensitive AS568A-114 (varies with application) Products Part Number GS101201 GS101202 Leads Connector** Delphi Metri-Pack 150 20 AWG x 1 m **Mates to Delphi connector 12162280 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. www.cherryswitches.com Page 1 of 2, Last saved by 2014-11-05, Specifications subject to change without notice. Recommended External Pull-Up Resistor Volts DC Ohms 5 1k 9 1.8k 12 2.4k 15 3k 24 3k Open Collector Sinking Block Diagram Dimensions mm (inches) GS101201 GS101202 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.
