Encoder couplings are an ideal fit for precision sensor and encoder applications, which require a coupling that is both flexible and accurate. Encoder couplings are designed to be torsionally stiffer with less wind-up than commodity style single beam couplings for increased performance and accuracy. Encoder couplings are machined from a single piece of aluminum or stainless steel and have a multiple cut design to accommodate parallel misalignment, angular misalignment, and axial motion.
