A typical linear encoder consists of a scanning unit and a scale. The scale is generally glass and is cemented to a support, usually an aluminum extrusion. The scanning unit contains a light source, ...

Optical or magnetic linear encoders handle high-res needs in dirty jobs. Linear encoders help minimize errors in motion transmission such as backlash, hysteresis, abbe errors, ball-screw thermal ...

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 ...
