GVS-H03 Hall-Effect Gear Speed Sensor
Description
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:
1.Target material, geometry, and speed
2.Sensor/target gap
3.Ambient temperature
4.Magnetic material in close proximity
Features
1.Senses ferrous metal targets
2.Digital current sinking output (open collector)
3.Better signal-to-noise ratio than variable reluctance sensors, excellent low speed performance, output amplitude not dependent on RPM
4.Sensor electronically self-adjusts to slight variations in runout and variations in temperature, simplifying installation and maintenance
5.
6.EMI resistant
7.Reverse polarity protection and transient protection (integrated into Hall I.C.)
8.Wide continuous operating temperature range
Typical Applications
1.Automotive and Heavy Duty Vehicles:
2.Camshaft and crankshaft speed/position
3.Transmission speed
4.Tachometers
5.Anti-skid/traction control, ABS system
Industrial:
Characteristics will vary due to target size, geometry, location, and material. Sensor specifications were derived using a cold-rolled steel reference target. See table, for reference target configuration and evaluation conditions.

Target refrence and conditions
The Target Guidelines table provides basic parameters when an application is not restricted to a specific target.
Any target wheel that exceeds the follow-ing minimum specifications can be sensed over the entire temperature range of -40° to 150°C with any sensing gap up to 2,0mm. This data is based on a 102 mm diameter wheel, rotating 10 to 3600 RPM.
