Description
The TSL202R linear sensor array consists of two sections of 64 photodiodes and associated charge amplifier
circuitry arranged to form a contiguous 128 ?1 array. The pixels measure 120 糾 (H) by 70 糾 (W) with 125-糾
center-to-center spacing and 55-糾 spacing between pixels. Operation is simplified by internal control logic that
requires only a serial-input (SI) signal and a clock.
The TSL202R 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.
