Online self-diagnostics Digital data transmission In addition to transmitting rotational position values, the KCI Dplus inductive rotary encoder for elevators also measures axial motion. When mechanically coupled with the armature plate of the brake, the KCI Dplus can detect the brake stroke. Based on this information, the subsequent electronics can determine the state of the brake released or engaged and the amount of brake wear. These temperature data can then be used to infer the presence of malfunctions.

The markings, or signal periods, on incremental encoder scales are spaced evenly apart, while absolute encoders use more complex patterns to sign specific location Sealed or enclosed linear encoder designs allow for design flexibility based on the environment.
Where contaminant levels are high, sealed encoders with the highest IP ratings protect the delicate components of the encoder to ensure lasting performance.
Where contamination is less of a factor, exposed encoders are an option. Proper mounting of encoders is also crucial to performance. In particular, the specified distance tolerance between the scale and scanning head scanning gap causes only a negligible change in the signal amplitude.
This variety makes HEIDENHAIN the source for nearly any application—including machine tools, semiconductor machines and medical machines—combating the biggest issues that erode precision and production. Thermal expansion, deformation of drive mechanics or screw pitch issues are common, especially in machine tools.
High long-term speed stability. Vibration can cause any number of problems, depending on the application, from unnecessary heat in always-on applications to imprecise outputs in metalworking.
In many cases, complex systems do not have a lot of space to spare. Industries we serve.
