More performance for your linear and rotary motors

HEIDENHAIN has developed the next generation of scanning for inductive measurement technology. The new inductive scanning method offers benefits for compact drive systems in highly demanding automation applications: little signal noise, low speed ripple, less cabling thanks to the EnDat 3 interface and the recording of operating status data.

Additional functions often open up new possibilities, and sometimes even completely new fields of application, for machines and production equipment. That is why HEIDENHAIN and the brands AMO, LEINE LINDE, LTN, NUMERIK JENA, RENCO and RSF also offer an extensive selection of products with added value for your specific requirements. These include applications with particularly high accuracy requirements or demands on process reliability.

The next generation of inductive scanning: ECI 1122 and EQI 1134

Inductive scanning fundamentally offers a large number of benefits in any application. These qualities include compact dimensions, wide mounting tolerances, high permissible operating temperatures, resistance to contamination and being insensitive to magnetic fields. The next generation of inductive measuring technology from HEIDENHAIN, which was first used in the ECI 1122 and EQI 1134 compact rotary encoders, now significantly expands this list, particularly for compact drive systems in highly demanding automation applications. Additional benefits are little signal noise, low speed ripple, less cabling and the recording of operating status data. This is made possible by increasing the resolution of the singleturn position to 22 bits, which in turn leads to a significant improvement in controller performance in the motor. The EnDat 3 interface makes it possible to connect the HMC 2 single-cable solution.

KCI 1318 FOT and KBI 1335 FOT with integrated bearing cover

Particularly compact and also good at heat dissipation: thanks to fan-out technology (FOT), HEIDENHAIN was able to attach the electronic components and conductive tracks directly to a metal carrier for the KCI 1318 FOT and KBI 1335 FOT variants. This means, for example, that they can be used as bearing cover. Not only does this reduce the space required and the necessary number of parts, but it also makes direct outward heat dissipation through the metal carrier possible. In this variant, the circular scale features a blind hollow shaft holder.

Product information about the PressFit rotary encoders

The new PressFit rotary encoder:
Reliable and automated mounting

A tolerance sleeve is inserted into a precise circular hole in the motor housing. The encoder, with its PressFit flange, is then pressed inside to create a friction fit. Finally, a single central screw fastens the encoder to the motor shaft. This process saves space, permits automated assembly, and allows assembly monitoring via force measurement. These are key benefits of the ECI 1119 PressFit (singleturn) and EQI 1131 PressFit (multiturn) rotary encoders.

The benefits:

Automatable mounting
Faster installation
Wide mounting tolerances
