HALL-EFFECT GEAR-TOOTH SENSOR

The ATS612JSB gear-tooth sensor is a peak detecting device that

uses automatic gain control to provide extremely accurate gear edge

detection down to low operating speeds. Each sensor subassembly

consists of a high-temperature plastic shell that holds together a

samarium-cobalt magnet, a pole piece, and a differential open-collector

Hall IC that has been optimized to the magnetic circuit. This small

package can be easily assembled and used in conjunction with a wide

variety of gear shapes and sizes.

The gear-sensing technology used for this sensor subassembly is

Hall-effect based. The sensor incorporates a dual-element Hall IC that

switches in response to differential magnetic signals created by ferrous

targets. The sophisticated processing circuitry contains a 5-bit A/D

converter that self-calibrates (normalizes) the internal gain of the device

to minimize the effect of air-gap variations. The patented peak-detect-

ing filter circuit eliminates magnet and system offsets and has the ability

to discriminate relatively fast changes such as those caused by tilt, gear

wobble, and eccentricities yet provides stable operation to extremely

low RPM.

Pin 1 = Supply

Pin 2 = Output

Pin 3 = Capacitor

Pin 4 = Ground

Dwg. AH-006

These sensor systems are ideal for use in gathering speed, posi-

tion, and timing information using gear-tooth-based configurations. The

ATS612JSB is particularly suited to those applications that require

extremely accurate duty cycle control or accurate edge detection similar

to crank shaft applications. The lower vibration sensitivity also makes

this device extremely useful for transmission speed sensing.
