CSMB-24Recognition Semiconductor Магнитный датчик U

CSMB-24 recognition semiconductor magnetic sensor is HMS magneto-dependent sensor with high sensitivity, which is also called magnetic head. It is composed of semiconductor material indium stibnide(InSb) magnetic resistence chip and permanent magnet supplying the InSb magnetic resistence chip bias. N pieces single, 10mm width magnetic resistence chips line spread, and the detection witdh is nch*10mm. It can readout wide breadth, large quantities magnetic signals FEATURE: . High stability, SN good. . Non-contact detection, output stability, fast response. . Output volatge is irrelevant to the magnet's moving speed. . The seizure of the resistance is pure, strong anti-interference capability. . Chips line spread. Every channel responds simultaneously. . Wide detection width, low noise. Application: . Dynamic Money Detector . Static Money Detector . Dectection of Weak magnetic ink . Detection of RMB and Foreign currency . Detect the magnetic signal of bank notes . Detection of Magcard and Bar magnet Note1. Sensitivity: Amplify current with 1100 times, when magnetic head scanning surface aims at the tinsel (0.1mm) with 100mA, 50Hz A. C. And slide linearly with it slowly, then measure the peak-to-peak value of the output voltage with oscilloscope and the maximum value is sesitivity. Note2. Symmetry = |MR1-MR2|/ MR1 (or MR2). Note3. N is the quantity of output channels Note4. Some details of product models can be abtained in another way.
