Honeywell’s Hawk™ 1 inch fully-housed resolvers now available from TTI, Inc.
TTI, Inc., interconnect, relay & switch and discrete components, has announced the availability of the Hawk™ series of fully housed 1 inch resolvers from Honeywell’s Sensing & Controls division, which provide enhanced accuracy (±7 arcmin) for precise motion control. With the launch of the Hawk series, Honeywell now offers two off-the-shelf versions, as well as devices that can be customized to meet specific end-user needs.
Potential defence applications for the new Hawk resolvers include positioning for electro-optical systems, gimbals/communication pedestals, infrared systems, vehicle transmission systems, and test equipment. Potential space applications include positioning for satellites, satellite antenna, on board space stations, and space vehicle solar panel arrays.

The fully housed devices have a small outer diameter of just 1 inch, which suits them for use in space-constrained applications. The single speed operation (1 magnetic pole pair) allows for cost-effective angle resolution over a 360°+ range, and the wide excitation frequency range of 2000 to 5000 Hz provides a wide variety of choices with which to power the device. The transformation ratio of 0.45 or 1.0 offers customers two choices, further increasing flexibility within the application.

Hawk resolvers feature specifications including shock 50g/11ms and vibration 15g 10-2000Hz plus a wide operating temperature range of -50.8 to 93.3degC enabling the parts to be used in harsh military and aerospace applications. They also have a wide excitation voltage range of 2-15V allowing customers to standardize on one resolver that meets all their excitation voltage needs, simplifying sourcing and delivery and saving time.

Hawk resolvers feature a non-contact design and use space-qualified materials, helping them to meet multiple military/aerospace specifications including DO-160D, MIL-STD-202G, MIL-STD-810G, MIL-STD-81963B, MIL-STD-461F; they also comply with the space out-gassing requirement SP-R0022.

The new Honeywell resolvers are also available with a variety of options, including: custom trimming for tighter accuracy; various different connector and cabling styles; lightweight, corrosion-resistant titanium housing; plus a version that includes two independent resolvers within the same housing which provides back-up/fail-safe operation in critical applications.
