Optical Encoders

We offer a range of optical linear and rotary encoders ideal for machine tools used within the hobby and model engineering workshops. Offering the quality and performance expected within the industrial but at an affordable price.

Linear optical encoders are comprised 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 also 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).
