THE E20 is the latest rotary encoder from Elma Electronic and it combines an integral push switch with a long life mechanical encoder in an SMT package specifically designed for automatic assembly using either reflow or wave soldering. ELMA is available in Australia from Associated Controls (Australia) Pty Ltd .
By providing a separate snap-in shaft, not only can the E20 be mounted by standard pick-and-place nozzles, and mated with standard conductive or non-conductive aluminium shafts, but Elma is able to offer custom shaft configurations for volume applications.
Gold contacts and advanced design contribute to a minimum encoder life of 100,000 rotations, together with a switch life of 100,000 operations, ten times the life of alternative products.
Lead-free miniature coded switch delivers 3 Ncm torque and 10,000 cycle life for space-saving.
