Optical Encoders

We offer a range of industrial optical linear and rotary encoders from the leading digital readout manufactures. These include our brand M-DRO, Easson and Mitutoyo

Linear optical encoders comprise of an aluminium extruded beam enclosing a glass scale. The glass scale has a series of fine graduations, typically only a 20um grating. The reading head carriage has a second glass grating, a light source passes through both gratings and a series of optical sensors detect and count the graduations. A flexible lip seal between the reading head and beam, prevents the ingress of dust, swarf, and cutting fluids during operation.

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).
