This flexCoder technology—an encoder system comprising a sensor and rule that can be adapted to the position and shape of an application—can be built into a customer’s design. Both the sensor and the rule can be adapted. The available standard also can be applied by a magnet ring or encoder. This allows the compact sensor mount to be adopted, and modification is required only to the attachment of the rule on the customer’s shaft. With other applications, a standard Siko magnet ring is used, and the mounting of the flexible sensor array and the evaluation and interface electronics are adapted to the customer’s specific fixing options in the housing.
