New Japan Radio (New JRC) has recently developed a green LED reflective photoelectric sensor NJL5303R, which is a new product that combines a green LED (emission wavelength of 570nm) and a phototransistor, which is most suitable for pulse detection High-performance medical care equipment.
ã€summary】
At present, photoelectric pulse detection equipment mainly uses infrared light to measure blood. The NJL5303R is different in that it uses green light with a 570nm emission wavelength, which enables high-sensitivity measurement. This product also uses a reflective photoelectric sensor, which encapsulates the green LED and phototransistor into a small COB package. In this way, body parts can be measured freely and flexibly, and it is widely used in various medical and health care equipment such as wearable smart electronic products and pulse measuring instruments of new test methods.
ã€Features】
1. Can expand the scope of application of pulse measurement equipment
The reflective photoelectric sensor used by NJL5303R makes the measurement method more free, and the application range covers pulse measuring instruments with wearable electronic products and new test methods.
2. Use the best emission wavelength for pulse measurement
The NJL5303R uses green light with a 570nm emission wavelength. Compared with infrared light, the reflectivity is higher, the measurement sensitivity is higher, and the S / N ratio characteristics are improved.
Product performance
• Emission wavelength 570nm
• Output current 20uA typ.
• Package COB package (1.9mm & TImes; 2.6mm & TImes; 0.8mm)
• Lead-free and halide-free
• Comply with RoHS standards

Screen Resolution
There are generally three screen resolutions for office projectors:
One is a 4:3 screen suitable for office PPT playback. The first is the SVGA machine with the lowest price and the highest cost performance. This kind of machine is generally priced at around 2500 and has powerful performance. The disadvantage is that the resolution is 800X600, which is relatively low. The second is the XGA machine, which is an upgraded version of the SVGA machine with a resolution of 1024X768.
The other is the 16:10 aspect ratio screen used by some foreign-funded enterprises, which is the 1280X800 resolution of WXGA. However, with the transparent price of 1080p projectors, more and more companies will choose full HD 1080p projectors as their office projection solutions.
Office Projector Features
According to the needs of different office environments, office projectors are roughly divided into three categories.
One is a conventional projector that is placed or hoisted in the conference room, the second is a Portable Projector that can be carried around, and the third is an ultra-short-throw projector that is convenient for work reports and speeches.
Wireless Office Projector
With the advent of the Internet era, the emergence of a series of wireless office series has added new members to the office projectors. The wireless office projector is realized by the built-in wireless module of the ordinary office projector. Wireless office makes people do not need to switch signal lines frequently in office meetings, allowing people to have a better experience in meetings!
