November 23, 2009 - Electro-Optical Encoders feature redundant photo-detector and light path to monitor encoder LED light output. Light-intensity feedback is then used by circuit to ensure maximum performance and life of quadrature output. Encoders allow for high encoder wheel resolution as well as durability.

Newly Redesigned Encoders Make CTI Trackballs Unbeatable

Each high-reliability trackball from CTI Electronics utilizes newly redesigned electro-optical encoders, patent pending. Additionally, these new electro-optical encoders feature a redundant photo-detector and light path to monitor the encoder LED light output. A novel circuit uses this light-intensity feedback signal to ensure that the quadrature output withstands the test of time - without compromising performance. Not only do our trackballs offer very high encoder wheel resolution, they also provide long-term reliability and durability.

In that CTI is building its own optical encoder, as opposed to purchasing a photo-detector sensor, customers can be assured of not only lasting reliability, but also long-term availability. This is especially important in products that require regulatory approvals, have long-term market requirements, or would be costly to redesign should an off-the-shelf photo-detector become obsolete.

Our strategy is to produce all of the key sensors used in our products, allowing CTI to regulate quality, reliability and long-term availability.
