Introducing JRC's Silicon Phototransistor-Type Ambient Light Sensor
Original optical-filter achieves spectral sensitivity of human eye
May 30th, 2007 - New Japan Radio Co., Ltd. has introduced the NJL7502L
silicon phototransistor-type ambient light sensor to the market, for ON/OFF control of
interior lights, toys, TVs, etc. according to brightness of surroundings, and
for automatic control of display brightness.
The NJL7502L is configured with a phototransistor plus an optical filter that uses New Japan Radio’s original resin lamination technology to reduce the risk of malfunction caused by infrared rays. With spectral sensitivity approaching that of the human eye, the sensor is exceptionally accurate for many control applications.
Eco-friendly silicon material is used for the phototransistor block, making this product an ideal replacement for the CdS (cadmium sulfide-based) cell-type ambient light sensors currently most commonly used on board, in accordance with the RoHS Directive.
The NJL7502L is housed in a top view, pin-type package, for easy CdS cell replacement.
Significant Features
• Sensitivity approaching that of the human eye
• Lead pin, top view-type package
• Phototransistor uses eco-friendly silicon
• Lead-free
The NJL7502L outputs sufficient light current more efficiently than conventional photo diode-type sensors do.
Features and Characteristics
