Linear Encoders

March 2, 2009

The LIF 481V, LIP 481V and LIP 481U are linear encoders for use with vacuum technology. The first two models are for high vacuum to 10 to 7 millibar, the latter is for ultrahigh vacuum up to 10 to 11 mbar. The LIF and LIP encoders consist of a glass scale, scanning head and the interface electronics. The cable between the scanning head and interface can be up to 3 meters in length. The vacuum compatible interface electronics can be placed either inside or outside the vacuum chamber. Available encoder accessories include fixing clamps, fixed point holders, vacuum feedthroughs, vacuum-compatible epoxy and extension cables.
