Overview

HEIDENHAIN Grating Ruler 689680-19 Purpose $r $n Taking a transmission grating as an example, when a small angle θ is formed between the lines on the indicator grating and the lines on the scale grating, and the two grating facets are placed relatively parallel to each other, under the illumination of a light source, they are located on almost vertical grating patterns, forming alternating light and dark stripes. This type of stripe is called a "Moir é stripe" (as shown in Figure 2). Strictly speaking, the direction of Moir é fringe arrangement is perpendicular to the bisector of the angle between the two grating lines

HEIDENHAIN Grating Ruler 689680-19 Purpose

Reliable sealing design effectively protects the LS 400 grating ruler from contamination. The wide scanning area further reduces sensitivity to contamination. Local foreign objects on the measurement benchmark hardly affect signal quality or measurement accuracy.

HEIDENHAIN linear grating ruler is easy to install. The design of the guide rail system allows for loose installation tolerances, making it quick and easy to install.

LS 400 is a high-precision, sturdy, and compact linear grating ruler. Moreover, due to its compact size, this grating ruler is an ideal choice for applications with limited installation space.

The length of the linear axis reaches 2040 mm

The LIC series linear grating ruler not only has high accuracy, but also supports high-speed motion. The measurement step distance is only 1 nm and the motion speed can reach up to 600 m/min. Position measurement, excellent anti pollution performance, and high reliability.

Compact structure, can be installed in limited space

The key component of the grating detection device is the grating reading head, which consists of a light source, a converging lens, an indicator grating, photoelectric elements, and an adjustment mechanism. There are many structural forms of grating reading heads, which are divided into direct receiving reading heads (also known as silicon photovoltaic reading heads, mirror reading heads, beam splitter reading heads, metal grating reflection reading heads) according to their structural characteristics and usage scenarios.

The LC series linear grating ruler provides consistent high precision. High quality, wear-resistant ceramic connectors prevent wear errors of grating rulers throughout their entire lifecycle.

Equipped with installation rails for easier installation

The linear grating ruler can measure the position of the linear axis without any intermediate mechanical connectors. Therefore, it can avoid many potential sources of error, such as backlash, pitch errors, or heating of circulating ball screws. As long as the position accuracy is strict and the processing speed is high, then the linear grating ruler.

Interface: 1 VPP and TTL

The LC 100 linear grating ruler provides functional safety features and mechanical connection anti loosening protection function. After integration into the system, this solution can provide SIL 2 level safety, minimizing failures and supporting the safe operation of machine tools.

Efficient sealing design, equipped with double sealing strips, effectively prevents chips, dust, and coolant from entering. The sealing strip and reading head outlet adopt a diagonal layout, and the encoder can be installed vertically or laterally.
