MJ-VR62 Hall speed sensor

● MJ-VR62 Hall speed sensor using hall effect. It was made by magnetic resistance as sensing elements . It is a new type speed sensor. Core component is the use of magnetic resistance as the detection element, and then through a new signal processing circuit to make noise reduction, function better. When the test object with the projections (or recesses) of the magnetic or magnetically permeable material, with the measured object is rotated, the magnetic resistance of the magnetic field change is detected and converted into an alternating electric signal, the sensor-circuit signal amplification, shaping, good rectangular pulse signal output measurement frequency range wider, more accurate and stable output signal, simple installation, oil and water.

●By comparison with other types of tooth waveform output speed sensor, the measured speed error minimal and linear characteristic has a good consistency. Its object is magnetic induction or magnetic materials, such as magnets, iron and electrical steel and so on. Has been widely applied in the field of gun power, automotive, aviation, textiles, petrochemicals and so on.

MJ-VR62 Hall speed sensor has the features as follow: 

● high sensitivity, high reliability, long life, long trigger distance;

● trigger signal is iron (soft) magnetic materials;

● long distance transport, strong anti-electromagnetic interference ability;

● good impact resistance and vibration resistance.

parameters of gear

Outside diameter of gear: 99.3mm; Number of teeth: 60; modulus: 1.57 

( above data is the parameters of one example, modulus can be from 1.5 to 2 ) 

when install the sensor, make the red LED in the stern perpendicular to the surface of gear and root of outgoing line connected.

outgoing lines of the sensor are red line as power wire, black line as ground wire and white line as signal output wire.

 

Because it is easy to use and install, good generality, so it is widely applied in many fields. Especially in low speed or super-low speed non-contact detection, it has the characteristics that other sensors cannot reach, which fills the gap of magneto-electric sensor with the measurement range 50~5000Hz in domestic (detection distance is only 0.5 mm; proximity switch cannot detect small mould teeth); in middle high speed non-contact detection, it can replace Hall switch directly.
