Improved Resolutions for Miniature Position Sensors
Mon, 06/15/2009 - 11:21am
The miniature Tracker position sensor has improved 0.5 µm resolution and additional packaging options. It is suitable for a wide range of applications including precision biomedical devices and optical instrumentation. In addition to the standard TSSOP or dice-on-foil versions, the Tracker position sensor is offered in custom chip-on-board and miniature wafer-level chip scale packaging with footprint as small as 2.5 x 3.9 x 0.6 mm. The sensor is significantly smaller than miniature optical encoders and does not require a light source. The on-chip encoder provides direct digital output using standard I2C protocol, eliminating the need for external pulse counters and enabling much smaller total system size.
