Hamamatsu has released a new range of linear output photo-ICs to replace traditional photoconductive cells (also known as LDRs) which have for many years been used in visible light sensor products.
As photoconductive cells are fabricated from cadmium, their use in consumer electronic equipment will be restricted when new European RoHS Legislation is implemented in July. The new replacement S9648 series of photo-ICs are fabricated from silicon, and are therefore compliant with the new legislation.
With a spectral sensitivity similar to the human eye in the visible range and with internal electronics amplifying the photocurrent signal by approximately 1000 times, the S9648 device provides an ideal replacement to older CdS devices. The new range can be easily configured as a replacement for most existing CdS photoconductive cells due to their end looking plastic package construction, says Hamamatsu. The package is a similar shape to the end-looking TO18 and TO46 metal packages and to the -5R range of plastic-moulded end-looking CdS cells currently on the market.
According to the company, the performance of the S9648 series, such as excellent linearity and low output fluctuation with temperature, far surpasses that of the older photoconductive cell technology.
The S9648 series is well-suited for applications such as energy-saving sensors for televisions/monitors, light dimmers for the LCD panel, office and industrial lighting control, automatic contrast control functions as well as a wide variety of general light level measurement applications.
