Product Description

GVS-02 Dual-Channel Hall-Effect Speed Sensor
Description
Gvs-02 series dual channel speed sensor has a small volume and good performance, excellent performance and high measurement accuracy. It is used to detect the rotational speed, linear speed and acceleration of wheel axle, rack, concave convex keyway, etc. Two channels of the sensor
The two channel are independent, output square wave with different phase. According to the phase advance or lag between the two channels, the positive and negative rotation can be identified,
Easy to install. Polarity and short circuit protection, wide speed measurement range, zero speed and high speed detection, wide temperature range and strong seismic resistance.

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 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:

1. Camshaft and crankshaft speed/position
2. Transmission speed
3. Tachometers
4. Anti-skid/traction control, ABS system 

Industrial: 

1. Sprocket speed
2. Chain link conveyor speed and distance
3. Stop motion detector
4. High speed low cost proximity
5. Tachometers, Counters
6. Gear tooth Sensor
