Long machine tool axes are increasingly being equipped with linear drives, and HEIDENHAIN’s new LC 201 absolute linear scale was introduced to specifically meet those drive position feedback needs. This new scale is a single-section METALLUR tape encoder that’s ideal for use in linear motor applications that may be required to reach high acceleration levels within the linear drive systems.
The encoder has an absolute 2-track graduation and a large single-field scanning window – using a reflective light method of scanning. This produces high signal quality and resistance to contamination, all with no homing routine required at start-up. This new single-section encoder is available in measuring lengths from 440 to 4,240 mm, and the multi-section version goes up to 28 meters or more with the TNC Control. This new encoder uses the same reader head and cables as its multi-section older brother.
Developed as an addition to the LC 200 linear encoder family, the LC 201 has its same form, fit and functionality. Also, the entire LC 2xx series encoders are bolt-hole compatible with HEIDENHAIN’s LB 382 series encoders, thereby providing a simple upgrade path for existing machines from incremental to absolute feedback.
Special features of the LC 2xx series encoders include:
- Absolute feedback in a one-piece scale body.
- Selectable thermal properties.
- Improved end blocks with integrated sealing air throttle.
- Multiple scanning units can be installed on one scale.
The encoder is produced with the ultrafast Endat 2.2 interface and allows speeds up to 3 m/sec.
