ON Semiconductor has unveiled a family of Python CMOS image sensors, designed specifically for industrial applications. These devices boast of global shuttering and 4.8micron pixel size.

The first three devices come with resolutions of 300k, 500k and 1.3Mpx and are intended to address the needs of machine vision, inspection and motion monitoring, as well as security and surveillance applications including intelligent transportation systems.

On Semi has patent coverage for in-pixel correlated double sampling, offered in the Python range, which the company claims results in CCD-like performance. The Python pixel combines a read noise of less than 9 e-, with 7.7V/lux sensitivity and frame rates as high as 850fps (VGA format). A configurable sequencer also allows on-the-fly updates to the sensor configuration.

The sensors operate across the -40°C to +85°C industrial temperature range.

The first three sensors offer resolutions of VGA, SVGA and SXGA with higher resolutions planned for release. All are pin-to-pin compatible with one-another and with the existing VITA1300 image sensor.

"Python offers an image sensing solution that not only provides appealing levels of speed without compromising image quality, but is also configurable and flexible enough to provide simple integration across multiple resolutions," said Thad Smith, director of the image sensor business unit at On Semi, in a statement.
