Product Description GVS-001 Hall-Effect Gear Speed SensorDescription GVS Series Tooth Sensors use a magnetically biased Hall effect integrated circuit to accurately sense movement of ferrous metal targets. This specially designed I.C., with discrete capacitor and bias magnet, is sealed in a probe type package for physical protection and cost effective installation. Output is digital, current sinking (open Collector). Reverse polarity protection is standard. If power is inadvertently wired backwards, the sensor will not be damaged. Optimum sensor performance is dependent on the following variables which must be considered in combination: Target material, geometry, and speed Sensor/target gap Ambient temperature Magnetic material in close proximity Features Senses ferrous metal targets Digital current sinking output (open collector) Better signal-to-noise ratio than variable reluctance sensors, excellent low speed performance, output amplitude not dependent on RPM Sensor electronically self-adjusts to slight variations in runout and variations in temperature, simplifying installation and maintenance Fast operating speed - over 100 kHz EMI resistant Reverse polarity protection and transient protection (integrated into Hall I.C.) Wide continuous operating temperature range Typical Applications Automotive and Heavy Duty Vehicles:Camshaft and crankshaft speed/position Transmission speed Tachometers Anti-skid/traction control, ABS system Industrial: Sprocket speed Chain link conveyor speed and distance Stop motion detector High speed low cost proximity Tachometers, Counters Gear tooth Sensor Specifications Product TypeHall-Effect Gear Tooth Sensor Probe HousingPlastic ProbeSupply Voltage4.5 Vdc to 24.0 Vdc Supply Current (max. @ 25 °C)20mAOutput TypeSquare wave signalTermination TypeLead WireOperating Temperature Range-40 °C to 150 °C [-40 °F to 302 °F]Output Voltage0.4 Vdc max.Output Current (max.) 40 mA Vane and Geartooth Target MaterialCold Rolled Steel, 1018 or Low in Carbon (Annealed)Target RPM10 RPM min., 3600 RPM max.
