Description
The TSL201R−LF linear sensor array consists of a 64
×
1 array of photodiodes and associated charge amplifier
circuitry. The pixels measure 120
μm
(H) by 70
μm
(W) with 125-μm center-to-center spacing and 55-μm
spacing between pixels. Operation is simplified by internal control logic that requires only a serial-input (SI)
signal and a clock.
The TSL201R−LF is intended for use in a wide variety of applications including mark detection and code
reading, optical character recognition (OCR) and contact imaging, edge detection and positioning as well as
optical linear and rotary encoding.
