  • Two modes of operation:
  • Can be used as a lightweight Super High Resolution Low-Inertia Trackwheel control as used in "Arkanoid"
  • Can also be used as a spinner with the addition of one of two sizes of fly-weight to provide inertia giving long spin-times of up to 20 seconds.
  • Correctly-designed flywheels with mass concentrated at the larger radius.
  • Ultra-high resolution. Unbeatable 1200 pulses per revolution..
  • Super-tough quality. Unit is manufactured by a supplier of encoders for high-speed motor usage and is almost identical to their industrial unit.
  • Dual sealed ball-bearing races give the ultimate in smooth control.
  • One-Piece bearing housing/body CNC machined from a solid alloy billet
  • Available in two versions, for direct connection to USB, or for connection to our I-PAC 2, Ultimate I/O, Opti-PAC or Mini-PAC interfaces.
  • In USB mode, this is the worlds only USB 2.0 spinner. USB 2.0 enables a 16-bit interface and a faster packet-rate than USB 1.1 Vital to avoid slowdown or backspin.
  • Usage not limited to gaming! Also suitable for precision control applications, CNC interfacing and other rotary measurement applications.
