We offer a range of optical linear encoders suitable for a wide range of machine tools, inspection machines, jigs and metrology applications.
Linear optical encoders are comprised of an aluminium extrusion 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, with a light source that passes through both gratings; a series of optical sensors then 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.
