Product Details

Quantum Devices, Inc. Model HR12 provides an improved feedback solution in applications typically using modular encoders.

The HR12 provides feedback capabilities where the others leave off – high line count resolution, high temperature operation, rugged bearing construction, large tolerance to radial and axial shaft play, commutation for brushless motor control, with a strain relieved cable. Quadrature output with index pulse and three-phase commutation provided with industrial 26C31 differential drivers. A flexible member allows for much greater tail shaft run out and TIR than can be tolerated by modular encoder designs, plus it provides 30 degrees of rotation for commutation timing.
