An increasing number of high-resolution encoders have been introduced to the market in recent years. With its compact ENX 16 RIO, maxon motor has presented a high-end model. But what applications benefit most from high-encoder resolutions?
The requirements of encoders are continuously increasing. This is particularly true for positioning applications such as the placement of electronic components. The reason for this is the increasing number of electrical contacts and the simultaneous decrease in the housing size of modern, highly complex integrated circuits such as microprocessors or programmable logic modules (FPGA).
For example, a modern WF-XBGA housing as per JEDEC standard MO-298, with up to 2,601 contacts and a 0.4mm grid size requires positioning accuracy of 0.4°m, or 1/900 of a revolution.
