ONOSOKKIElectromagnetic speed sensorMP-9820The MP-9820 is a non-contact magnetoelectric speed sensor, which consists of a magnetoresistive element, a permanent magnet, a DC amplifier, and a voltage regulator. When used with a detection gear, it can measure speeds from ultra-low to high speeds (1 to 100,000 r/min (60 P/R)) and output stable square wave signals. As a sensor, the MP-9820 can be connected and used with the TM-3100 series speed indicator and the FV-1400/5300 frequency/voltage (F/V) converter. The test system has a wide test range and a wide range of applications. 1 Hz to 100 kHz ultra-wide signal detection range The highest level of frequency response performance in the industry - from ultra-low to high speeds, the test range is wide and the application field is wide. Non-contact detection method, the object being tested has no additional load, no friction, and no need for lubrication. Compact structure Built-in magnetoresistive element and waveform processing circuit Detection method Utilizes magnetoresistive element and magnetic material gear Detection gear is made of strong magnetic material (such as S20C, SS400, etc. (both are Japanese specifications)), involute gear module 0.5 to 3, tooth width 3 mm or more Detection distance is determined by the module of the detection gear Measurement speed range 1 Hz to 100 kHz (when using a 60 P/R detection gear, 1 to 100,000 r/min)* Output method Voltage signal output Output signal form Square wave, high level H: within +5 ± 0.5 V, low level L: below +0.5 V.
