Incremental-rotation or linear encoders are very common, but normally they do not provide a direction signal. This design shows an easy way to detect forward or reverse direction. Incremental encoders ...

An absolute encoder includes a coding disk in binary or gray code format, the electronics to read it, and communications circuits. A multiturn encoder may have several disks connected by gears as ...

Rotary quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...
