Application Examples (5)

Analysis Equipment A

Trackball rotation speed/direction detection

Usage

  • ・To detect the number/direction of disk rotations in each of the X and Y axes linked to the trackball rotation.

Issues & Requests

  • ・Want to reduce the number of components and assembly man-hours by simplifying the device structure.
  • ・Want to stabilize the soldering quality by surface mounting.

Solution

  • ・Adopted model:
    SMD type Photomicrosensor (photointerrupter)
    EE-SX1321
  • ・The number of components and assembly man-hours can be reduced by using a 2-channel type sensor instead of two photomicrosensors per axis.
  • ・The short and fixed distance between the two channels (beams) provides a stable signal and also can reduce the size of the trackball unit.
  • ・Adopting a surface mount device (SMD) reduces mounting man-hours and stabilizes the soldering quality.
