About Dynapar

Dynapar is a US manufacturer of rotary encoders, resolvers and condition-monitoring solutions headquartered in Gurnee, Illinois, where it was founded in 1955. With more than 50 years of engineering and manufacturing experience in rotary feedback devices, Dynapar describes itself as an industry leader in rotary encoder products and brushless/frameless resolvers, and notes it was ranked by Control Design magazine readers as the #1 supplier of encoders and resolvers three years in a row. Its range covers incremental and absolute rotary encoders — single- and multi-turn absolute models with standard industry protocols, including EtherNet/IP — optical and magnetic encoders, and resolvers from size 10 to 55, including high-temperature and radiation-hardened specialty models.

A current highlight is the HS35iQ smart encoder with PulseIQ technology, which adds on-board fault detection (insufficient voltage, cable integrity, coupling slip, overspeed, electronic failure and temperature) with LED or PLC-connected diagnostics, reflecting Dynapar’s expansion into condition monitoring with analytics. The business markets products under the Dynapar, Hengstler, NorthStar, Harowe and Encoder Technology brands, serving steel, paper, elevator, oil and gas, wind energy, medical, material handling and industrial servo applications worldwide. Dynapar operates within the Fortive group, following its earlier Danaher ownership.

GlobleMatch Trust Signals

A directory that doesn’t sell stars. Trust Signals are built only from verifiable facts — never from anonymous ratings, and never for sale. There is no single hidden score.

Public information coverage	8 of 9 fields on the standard profile could be filled from public sources. This counts how much public information exists about the company — not how good the company is. The nine fields are listed in the methodology. Claiming the profile lets the company complete the remaining fields itself.
Last verified	9 November 2026 — facts on this profile were checked against the sources listed below. Profiles are re-checked on a published 90-day cycle; this date is never quietly refreshed.
