As the disc passes between a light source and a photoelectric sensor ... encoders cost much less than optical versions and are more compact. Most use analog Hall effect devices mounted on a ...

Two caveats: Early-generation magnetic encoders using Hall-effect sensors and signal-processing circuits have less precision and slower dynamic responses than optical encoders. Magnetic encoders ...

Allegro's A1688 wheel speed sensor ... a dual-element Hall-effect circuit and signal processing that switches in response to differential magnetic signals created by magnetic encoders, or, when ...

Sunnyvale, Calif.—Maxim Integrated Products has introduced the MAX9621, a dual, 2-wire, Hall-effect sensor interface with analog and digital outputs. The MAX9621 enables the microprocessor to monitor ...

This custom linear Hall effect sensor is ... in the need for a linear sensor 100 mm in length, the specs for which — absolute sensing, no brushes or encoders, easily sourced parts — precluded ...

Compared to solutions using the Hall effect ... circuit, to eliminate the influence of low levels of noise. This Schmitt trigger cannot ensure functionality at high noise levels, however. Marked ...

Allegro Microsystems has introduced isolated differential current sensor ICs based on the Hall effect. Accuracy is typically +/-1% ... Inside there is a chopper-stabilised BiCMOS Hall sensor circuit ...

Most joysticks measure position mechanically using potentiometers or encoders. Only a few high-end models use Hall effect sensors. That’s the route [dizekat] took. Hall effect sensors are non ...

And with the hybrid circuit, the space required to build a DeviceNet, Profibus or Ethernet interface into devices such as rotary encoders, barcode readers and sensors is said to be greatly reduced.
