Fully housed, one inch diameter resolvers from Honeywell's Sensing & Controls division are available from TTI. There are two off-the-shelf versions as well as devices that can be customised. The resolvers provide accuracy of ±7 arcmin for positioning in electro-optical systems, gimbals or communication pedestals, IR systems, vehicle transmission systems, and test equipment. In space applications they can be used for positioning for satellites, satellite antenna, on board space stations, and space vehicle solar panel arrays. The single speed operation allows for cost-effective angle resolution over a 360°+ range, and the wide excitation frequency range of 2000 to 5000Hz provides a variety of choices to power the device. Specifications include shock 50g/11ms and vibration 15g 10 to 2000Hz and a wide operating temperature range of -50.8 to 93.3°C. The excitation voltage range is 2 to 15V. The resolvers have a non-contact design and use space-qualified materials, helping them to meet multiple military or 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. Custom options are also available.
