Honeywell has introduced the Honeywell Hawk Resolvers 1in Series, fully housed configuration, which provides enhanced accuracy (+/-7arc/min) for precise motion control.

The 1in Series resolvers are said to be manufactured and delivered up to 1.5 times faster than many competitors’ products, helping to meet special application requirements and minimise production time.

With the launch of the Hawk Resolvers, Honeywell now offers two off-the-shelf versions, as well as resolvers that can be customised to meet specific end-user needs.

Potential defense applications for the 1in series include positioning for electro-optical systems, gimbals/communication pedestals, infrared systems, vehicle transmission systems and test equipment.

Potential space applications include positioning for satellite, satellite-antenna, space-station and space-vehicle solar-panel arrays.

Features: shock specification of 50g, 11ms, vibration specification of 15g, 10 to 2,000Hz and operating temperature range of -50.8 to 93.3C, which allow for use in harsh military and aerospace applications; excitation voltage range of 2 to 15V, which allows customers to standardise on a resolver that meets their excitation voltage needs, simplifying sourcing and delivery, and saving time.

The Hawk Resolvers offer sensing in harsh military and space environments.

In addition to its non-contact design, the lack of electronics and the use of space-qualified materials, the Hawk Resolvers meet multiple military/aerospace specifications: DO-160D, MIL-STD-202G, MIL-STD-810G, MIL-STD-81963B and MIL-STD-461F, and comply with space outgassing requirement SP-R0022.

The fully housed configuration with bearing/shaft has a small outer diameter of 1in, which allows for use in size-restricted applications.

The single-speed operation (one magnetic pole pair) allows for cost-effective angle resolution over a 360deg range and the excitation frequency range of 2,000 to 5,000Hz provides a variety of choices with which to power the device.

The transformation ratio of 0.45 or 1.0 offers customers two choices, increasing flexibility within the application.

The Honeywell Hawk in Series Resolvers are also available with a variety of options, including: custom trim designed to allow tighter accuracy; connections that include custom lead wire, cable, connector on unit or connector on cable; titanium housing which provides enhanced durability and resistance to corrosion; lightweight; custom redundant version (two independent resolvers within the same housing), which provides reliable back-up/fail-safe in critical applications; transformer for 360deg rotation (continuous).
