With the new generation of inductive absoluteencoder The ECI / EBI 100 series extends Heidenhain's range of applications. Preferred applications are demanding applications such as hollow shaft and torque motors as well as cramped installation conditions of modern machine concepts. For these applications, the ECI 119 not only offers a singleturn resolution of 19 bit (524 288 positions / revolution), but also an extremely compact design and considerable functional reserves against contamination and mechanical load influences.
A special highlight of the extended series is the EBI 135. Its battery-buffered revolution counter (16 bit) enables a total resolution of 35 bits compared to the 19 bits of the singleturn device ECI 119. The inductive scanning makes it a particularly robust measuring device. Under normal conditions of use and appropriate design of the external battery supply, a battery life of approx. 10 years is achievable. In addition, an optional external temperature sensor can be connected and evaluated. The temperature value is transmitted via the EnDat 2.2 protocol.
The inductive absolute encoders of the ECI / EBI 100 series are now available with hollow shaft diameters 30, 38 or 50 mm. The hollow shaft also allows the passage of electrical cables, waves or supply lines. This can significantly reduce the design effort depending on the design of the machine. With the newly realized flange recess, the electrical connection technology can be optimized. It allows the electrical connection within the encoder contour, in particular in cramped installation conditions.
The ball bearingless design of the inductive absolute encoders of the ECI / EBI 100 series prevents additional friction torques and mechanical self-heating. At the same time, ball bearing damaging shaft currents, such as might occur when used on electric motors, do not come into effect. In addition, the encoders are suitable for a high working temperature range up to + 115 ° C and thus allow efficient motor design. An extended supply voltage range simplifies the design of the subsequent electronics and the permissible connecting cable lengths.
