nickel-plated steel
The core of the Controlflex is its unique functional element made of Delrin®. The design of this functional element - a flat parallel link system with flexure joints - combined with this technical plastic material gives the encoder coupling special properties.
It enables displacement compensation on one level with the resulting advantage of an extremely compact design. Not only does it always keep an eye on absolute sync but it also protects your rotary encoder bearings at all times, even if several millimetres need to be compensated for.
