A quadrature encoder uses two output channels offset in phase to detect both direction and position with greater precision.

Quadrature encoders work inmany applications to determinedisplacement and direction of mechanicaltravel. They vary in design, butthey all do the same thing: supply a setof square waves 90° out of ...

Quadrature encoders have many uses in position-sensing applications. This implementation uses a Xilinx complex programmable logic device (CPLD) to count the pulses from the encoder and determine the ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

If you are a novice to rotary encoders for human-machine interface, there is a potential pit-fall. Otherwise called quadrature encoders, they deliver two-bit gray-scale binary on rotation, with the ...

Measurement Computing's USB-QUAD08 high-speed quadrature encoder module provides simultaneous input and decoding for up to eight incremental quadrature encoders. A high-speed quadrature encoder module ...

I was thinking about using a hexadecimal control switch and ended up pondering what alternatives exist. For example, how about a quadrature encoder and an up-down counter. There appear to be a couple ...

[shantea] builds MIDI controllers, and after a successful first endeavor with a matrix of buttons and knobs, he decided to branch out to something a little bit cooler. It’s called Ceylon, and it’s ...

Two new direct-drive linear motors in Moticont's SDLM line feature a linear optical quadrature encoder to enhance accuracy. The engineers at Moticont, Van Nuys, Calif., designed two new high-speed, ...
