Sealed Linear Encoders
Sealed linear encoders from HEIDENHAIN are protected from dust,
chips and splash fluids and are ideal for operation on machine
tools. An aluminum housing and elastic sealing lips protect the
scale, scanning carriage and guideway from chips, swarf, dirt and
splashwater The scanning carriage travels in a low-friction guide
within the scale unit. It is connected to the external mounting
block by a coupling that compensates unavoidable misalignment
between the scale and the machine guideways.
Sealed linear encoders are available with full-size scale housings
for high resistance to vibration up to 30 m measuring length, as
well as slimline scale housing for limited installation space up to
1240 mm measuring length; with mounting spar up to 2040 mm.
