absolute encoder
| series | Instructions |
|---|---|
| LIC | The LIC open linear grating ruler is capable of absolute position measurement for travel up to 28 meters and high-speed motion. Its size and installation method are the same as LIDA 400. |
Encoder for outputting position values
| series | Instructions |
|---|---|
| LIP 200 | LIP 211 and LIP 291 incremental linear grating ruler output position information of position values. The sine scan signal is further divided by high-frequency division in the reading head, and its counting function converts the divided signal into position values. Like all incremental encoders, the absolute origin is determined using a reference point. |
Incremental encoder
| series | Instructions |
|---|---|
| LIP |
ultra-high precision The LIP open linear grating ruler has extremely small measurement steps, high accuracy, and repeatability. The scanning method is interferometric scanning, and the measurement reference is DIADUR phase grating. |
| LIF |
high precision The measurement reference of LIF open type linear grating ruler is the glass substrate grating manufactured by SUPRADUR process, using interference scanning method. The characteristics are high precision and high repeatability, particularly simple installation, limited position switch and zero return rail. The special model LIF 481 V can be used in vacuum environments of 10-7 bar (see its separate "Product Information"). |
| LIDA |
High speed motion and large measurement length The LIDA open linear grating ruler is particularly suitable for high-speed motion applications with a speed of up to 10 m/s. It supports multiple installation methods and is particularly easy to install. According to the corresponding application requirements, the substrate of Metallur grating can be steel strip, glass or glass ceramic. Also limited position switch. |
| PP |
2D coordinate measurement The measurement reference of PP two-dimensional encoder is the phase grating manufactured by planar DIADUR process, using interferometric scanning method. Used for measuring position in a plane. |
| LIP/LIF |
High vacuum and ultra-high vacuum technology Our standard encoder is suitable for low or medium vacuum applications. Grating rulers for high vacuum or ultra-high vacuum applications need to meet some special requirements. The design and materials used must meet the application requirements. For more information, please refer to the product information of "Linear Grating Ruler for Vacuum Applications". The following open type linear grating ruler is specifically designed for high vacuum or ultra-high vacuum application environments. • High vacuum: LIP 481 V and LIF 481 V |
New Signal Processing ASIC Chip for Heidenhain Open Linear Grating Ruler
The Heidenhain open linear grating ruler is an ideal choice for high-precision positioning or high-precision motion. To ensure that the grating ruler meets high-precision requirements throughout its entire lifecycle, Heidenhain has recently developed a new ASIC signal processing chip: HSP 1.0. Please watch the video on how the chip can almost perfectly compensate for signal changes and restore the initial signal quality.
