Ametek 1986A1GR25RX Resolver Assembly

Ametek Gemco 1986A1GR25RX Resolver Assembly is a rugged multi-turn foot-mount resolver package that provides absolute rotary position sensing with a 25:1 internal gear reducer and a rear electrical connector. Part of AMETEK Gemco’s 1986 Series, this brushless resolver uses a reference winding and SIN/COS outputs to generate two signals whose ratio indicates shaft angle; the resolver remains an absolute position sensor even when power is interrupted. The 1986A family is designed for harsh industrial environments and commonly features a 3/4" input shaft and aluminum mounting foot, with options for single-turn and multi-turn configurations. In this geared variant, the 25:1 reducer increases resolution and reduces motion to the sensor, making fine-position feedback feasible in compact installations. Typical applications include packaging, primary metals, stamping, automotive, tire and rubber, paper mills, and mining, where reliable, high-accuracy rotary sensing is required. The rear connector simplifies wiring in tight spaces, and AMETEK’s 1986 Series continues to offer robust performance in demanding environments where absolute position data is critical for control systems and automated equipment.
