Recently, Wuxi LerTech Technology Co., Ltd. announced the introduction of a new type magnetic image scanning sensor (model: LTM-XM-336B-0.5-AS), which is an upgraded version of its first-generation magnetic image scanning sensor introduced in August 2014.
With the serial output interface, the processed analog output signal can be directly provided to user's A/D chip modules.
In order to better identify counterfeit currency and other negotiable documents, the use of advanced magnetic coding is a recent innovation necessitated by the increasingly sophisticated methodologies available to compromise optically based scanning systems. Therefore, the signature of additional magnetic information encoded in currencies of many countries can be used to distinguish valid currency from counterfeit copies. This use of magnetic encoding was coupled with the development of high-density and high sensitivity magnetic pattern recognition sensors.
LerTech's magnetic image scanning sensor, combines the highest SNR magnetic chips, featuring wide gap characteristics, and high output, ensuring the reliable detection of varieties of strong and weak magnetic encoded information in many currencies. The multi-channel lineup includes a typical channel resolution of 50 DPI (higher resolution also available) and line resolution of 200 DPI (can be specially designed between 50 DPI and 600 DPI range). The effective scanning width can be up to 180 mm with the physical size of 193 mm * 16 mm * 40 mm (width * length * height), suitable for the whole image scanning for many currencies.
Dr. Jianmin Bai, who is in charge of LerTech's research and product development division, pointed out that "Different from the traditional gradient magnetic field detection methodology limited at low resolution, LerTech applies the total new design featuring absolute magnetic field detection in our magnetic imaging sensor products allowing real magnetic image to be detected. The ability to develop high resolution magnetic imaging sensors with this unique design promises to accelerate the use of magnetically encoded information in a variety of currencies and other negotiable documents."
Lertech is a world leader in magnetic sensor manufacturing and designing, Lertech innovation is focus on magnetic image scanning, magnetic signal detection, and biochip technology.
