Heidenhain Expands Popular Kit
Encoder Series for Better Motion
Control
SCHAUMBURG, IL (GLOBE NEWSWIRE) — Heidenhain is
proud to introduce a new high accuracy motion feedback
encoder that can now be used for absolute positioning in
machines in the semiconductor, metrology and robotic industries.
This new LIC 3100 absolute kit encoder is an additional
offering that fits between Heidenhain’s already successful LIC
4100 and 2100 series. It is expected to be of special interest
to users since it is also especially tolerant to contamination
and has very loose mounting tolerances.
Heidenhain’s high accuracy motion feedback encoder is now available for
use in positioning in semiconductor, metrology and robotic equipment.
mounted directly to the motion axis surface with an adhesive
backing on the steel tape.
It is important to note that the graduation of the new LIC
3100 encoder is carried by a sturdy stainless-steel tape. This
steel tape scale has a 2-track graduation resulting in a period
of 80 microns. The tape scale is offered in rolls at 3m, 5m,
and 10m lengths and can be inserted into an aluminum
extrusion for better thermal growth behavior or can be
The reader head of the LIC 3100 can output a measuring step
of just 10 nanometers and maintain a velocity of 10 meters
per second. It is offered with the well-known EnDat 2.2 high
speed serial electrical interface as well as five others, making
it plug-and-play compatible with motion controllers. The
interpolation error, or cyclical error, is merely +/- 100 nanometers,
allowing the encoder to provide smooth constant
velocity and allow linear motors to function more efficiently.
Mounting of the reader head to the scale is fast and simple
due to forgiving mounting tolerances and easy-to-use handheld
diagnostic tools like Heidenhain’s PWT 101. A zero-datum
position can be programmed anywhere along the scale
length.
