Product Details

Quantum Devices, Inc.'s JR12 model offers a superior feedback solution for applications typically employing pancake resolvers with the same threaded shaft and jam nut mounting. The JR12, with its height under one inch and the robustness of a bearing encoder design, can deliver significant performance boosts in contexts usually limited by traditional resolvers or modular encoder solutions.

The JR12 provides output options including a quadrature with index pulse and three-phase commutation. Its flexible part accommodates a greater tail shaft run out and TIR than what modular encoder designs usually allow, plus its integrated mounting flange removes the necessity for costly servo mounting clips.
