Product Details

Quantum Devices, Inc.'s JR12 model offers an upgraded feedback solution in applications that traditionally use pancake resolvers with the same threaded shaft and jam nut mounting. The JR12, with a height of less than one inch and the reliability of a bearing encoder design, can significantly improve performance in situations that are typically limited by conventional resolvers or modular encoder solutions.

The output options of the JR12 include a quadrature with an index pulse and three-phase commutation. A flexible component accommodates greater tail shaft run out and TIR than most modular encoder designs, and the mounting flange removes the need for expensive servo mounting clips.
