  1. HEIDENHAIN KOREA LTD. is a subsediary of DR. JOHANNES HEIDENHAIN GmbH. DR. JOHANNES HEIDENHAIN GmbH develops and manufactures linear and angle encoders, rotary encoders, digital readouts, and numerical controls for demanding positioning tasks. HEIDENHAIN products are used primarily in high-precision machine tools as well as in plants for the production and processing of electronic components. With our extensive experience and know-how in the development and manufacture of measuring devices and numerical controls, we create the groundwork for the automation of tomorrow’s plants and production machines.

 Press Releases

  • The new LIP 6000 exposed linear encoder from HEIDENHAIN, featuring interferential scanning, enables exceptionally accurate position measurement as well as permanently reliable signals, all within in a compact design. With a very small interpolation error of only ±3 nm, a low noise level of just 1 nm RMS, and a baseline error of less than ±0.175 µm at a 5 mm interval, this encoder is predestined for applications requiring constant speed control or high positioning stability at standstill.

    The LIP 6000 owes its exceptional characteristics in part to the new HEIDENHAIN signal processing ASIC HSP 1.0, which ensures consistently high-quality scanning signals throughout the entire service life of the encoder. To this end, it continuously monitors the scanning signal: if the signal amplitude decreases, then the HSP 1.0 readjusts it by increasing the LED current. The resulting increase in LED light intensity has only a minimal worsening effect on the noise component in the scanning signals, even during heavy signal-stabilizing intervention. This stands in stark contrast to systems that perform amplification within the signal path. At the same time, the HSP 1.0 also ensures that the original, ideal signal shape is maintained despite contamination.

    Additional special features of the LIP 6000 include its integrated homing and limit functions. The homing function enables position detection and thus faster system homing—a clear advantage, especially for long axes with sizable traverse ranges. The integrated limit function allows for the detection of limit positions without the need for additional measures. For this purpose, limit plates are easily positioned as desired during mounting. In conjunction with the information from the homing function, the limit function makes it possible to differentiate between whether the right or the left end position has been traversed by the scanning head.

    The compact design of the LIP 6000 derives from the high integration density of its scanning and signal-processing components. This integration density allows for a scanning head that is a mere 26 mm long, 12.7 mm wide, and 6.8 mm high and that features a very low mass of only 5 g. It is also available in two versions, with a choice between having the cable outlet on the right or the left side, depending on the mounting situation. Linear scales are available in lengths of up to 3,040 mm.

    Because the scanning head and linear scale of the LIP 6000 are an unpaired system, any combination between them is possible. The nominal distance between the scanning head and the linear scale is 0.75 mm, with a permissible variation of ±0.2 mm. An offset of ±0.2 mm is permitted for lateral movements. For rolling and pitching motion, the scanning head tolerates ±5 mrad of rotation about both the crossfeed axis and the longitudinal axis. Yawing movements of ±2 mrad about the vertical axis are also permitted. These generous mounting tolerances facilitate assembly and make it possible to use the LIP 6000 in mounting areas with mechanically simple layouts.

BEWARE - Special Warning Notice about ExpoGuide and FAIRGuide

With the ongoing solicitations, SEMI would like to continue to alert you with questionable professional practices perpetrated against exhibitors by FairGuide.com (Austria) and Expo Guide (Mexico), Event Fair - The Exhibitors' Guide with their misleading directory services. There may be others that we are not aware of and are hence not named here. 

These companies provide legitimate exhibition guides aimed at exhibitors across the globe offering online listing services. They use a form which resembles and organizer's free catalogue listing service, inviting exhibitors to complete the form for an entry in an on-line directory. Unsuspecting exhibitors who sign and return the form are then contracted into a three-year, non-retractable agreement, which could cost the exhibitor a significant amount of money, with very limited foreseeable benefits. The details are often available on the form itself, but are often too small and insignificant to be noticed. It is always wise to really the small print before signing a contract, and if the information is impossible to read then the contract should not be signed. These publications have no connection with SEMI or any of our events, and it is important that all companies are made aware of this. 

Should you receive any communication from the Expo-Guide and Fairguide.com or related company, please IGNORE THEM COMPLETELY and DO NOT COMMUNICATE WITH THEM IN ANY WAY.
