Advanced Micro Controls, Inc. HT-20-8 Resolver Transducer

HT-20-8 Resolver Transducer from Advanced Micro Controls, Inc. (AMCI) is a rugged single-turn resolver transducer in the HT-20 family that converts a resolver’s rotor position into an electrical feedback signal for servo and motion-control systems. It uses a 0.625-inch (5/8") front keyway shaft and is built for industrial environments, with enclosure options rated for NEMA 4 or 4X conditions. The unit weighs about 4 lb and offers a starting torque of 8 oz-in at 25°C, supporting reliable low-load positioning in demanding applications. While the base HT-20 is single-turn, the HT-20 family includes multi-turn variants (HT-20-(x)) with gear ratios ranging from 2:1 up to 16:1 to accommodate multi-turn position feedback when needed. Typical applications include industrial automation, robotics, CNC machinery, and other systems requiring precise resolver feedback to drive control loops, with a durable 5/8" shaft and robust construction that withstands frequent cycles in harsh environments.
