Optical Encoders

We offer a range of ultra-high precision optical linear and rotary encoders from the leading digital readout manufacturers. These include Acu-rite, Heidenhain and Mitutoyo. These leading brands are primarily fitted onto high-precision machine tools and automated systems used within the aerospace, medical and automotive sectors.

Options include incremental encoders, whereby the position is obtained by counting the individual gradations.  Alternatively absolute encoders detect current position value on power up of the scale. There is no need to travel a machine axis to establish a reference position.

Both “enclosed” and “open” linear optical encoders are available.  The enclosed type offer protection from dust, swarf, chips and cutting fluids; whereas the open or exposed linear encoders operate with no physical or mechanical connection between the reading head and scale.  These are typically installed when especially high accuracy is required.

Please feel free to contact our technical staff for further advice, or to arrange an on-site install by one of our engineers (UK only).
