O50 series trackballs from AVisum utilise Optical Navigation Technology

Now supplied by AVisum, O50 series trackballs use solid state Optical Navigation Technology in place of the traditional mechanical assembly of conventional trackballs.

This ensures that the only moving part in the entire assembly is the ball, the movement of which is sensed directly, eliminating the need for shafts, separate encoders and opto-couplers.

O50 series trackballs achieve this by using an optical beam of a specific wavelength that is focused precisely onto the finely patterned area of the ball to be read.

Resultant reflections are then directed through lenses onto the optical sensors for the capture of the sequential images. Rotation of the ball results in electronic outputs from the optical sensors which are further processed to produce the mainstream protocol interfaces such as USB, PS/2 and Quadrature.

Three versions of O50 series trackballs are available. The free running ball version requires a minimal ball tracking force of only 10 grams.

Fixed friction/Scraper ring varieties require an increased ball tracking force of approximately 80 grams.

Finally, the variable friction ring with removable ball model has a variable ball tracking force that can be set from loose (10 grams) to high (120 grams) in four steps.

O50 series trackballs also feature:

  • a IP68 waterproof rating
  • PS/2, USB or Quadrature output
  • no maintenance or moving parts
  • anti-vandal features
  • ESD safe operation; and
  • A self drainage and flush through facility.
