Optical Track Sensor

The Optical Track Sensor (OTS) is an exciting product family of PixArt. With its great surface detection capabilities, PixArt’s OTS products has so far been deployed in printing media, digital rotary tracking, smart device control and robot navigation applications to help improving their performance outcomes.
 
Considering that each application has distinct sensory needs, PixArt has divided its OTS products according to four key focuses: high accuracy, high speed, low power and wide coverage of surface materials. For instance, printers utilizing the accuracy-focused OTS products (PMJ9100S1 & PAT9102DM-T4QU) allow users to benefit from precise paper alignment that are required for professional business printing (with lowest error rate of ±0.015mm over 25mm travel distance). Printers that are built for speed printing can use our high-speed OTS products (PMT9101DM-T2QU & PAT9130EW-TKMT) to reach a speed of as high as 150ips, with the capability to detect paper edges, materials and pictures at the same time.
 
Our small form factor, low-power consuming models (PAT9125EL-TKMT/TKIT & PAT9126JA-TKIT), designed to play a core role in consumer applications, are able to reach a high 2000cpi resolution with merely 0.5mA of current consumption. In the realm of surface tracking, we understand how important yet painstaking it is to allow service robots to detect and distinguish various surface materials while in motion, so we invented PAA5100JE-Q and PAA5101EW-M to support wide surface-detection coverage which includes carpets, granite, tiles, wooden floor and highly glossy tiles.

Please refer to the table below which best describes your key application requirements, and find the most forefront fit for your next innovative product. It is our pleasure to work together with you to develop products that touch the consumers’ hearts.
