Short signal periods normally require very tight tolerances at the gap between the scanning head and the measuring standard. But exposed linear encoders from HEIDENHAIN provide wide mounting tolerances for easy installation. Within these wide tolerances, the quality of the output signals is barely affected.
The LIF 400 V linear enocders use interferential scanning technology to read a phase grating. Extremely small measuring steps and high accuracy are the results. What's more, their scanning head does not heat up significantly during operation, thereby avoiding temperature-related errors.
Continuously high signal quality
The ASIC HSP 1.0 developed by HEIDENHAIN ensures high scanning signal quality. If the signal amplitude decreases, the ASIC increases the LED current, thereby maintaining the ideal signal shape despite contamination while keeping the noise component low.
A built-in homing function enables position detection and therefore faster system referencing. This is a clear benefit on long axes. These encoders also feature an integrated limit function, enabling dependable end-position detection without additional measures.
For high-vacuum applications
Vacuum technology plays a key role in many state-of-the-art research and production processes, including electronics manufacturing, thin-film technology, materials research, biotechnology, medical technology and high-tech lab equipment.
Due to their many exceptional features, the LIF 400 V encoders can be used universally. Their high integration density gives them the added benefits of low weight and a compact form factor.
