Gear Tooth Sensor

We are offering gear tooth sensor, magnetic pick-up generates its own output. Magnetic pick-up senses motion of ferous (magnetic) material like geared wheel, bolt heads, keyways. In sine wave op pick-ups, the output voltage is directly proportional to speed of passing target. And in square wave op pick-up, the output is in form of square wave having amplitude equal to supply voltage.
magnetic pick up consists of permanent magnet, a pole piece and a sensing coil and electronic circuit. Anobject of iron, steel or other magnetic material passing closely by its pole face causes distortion of its magnetic flux field passing through sensing coil and pole piece, which in turn generate a signal voltage
application : magnetic pick ups are most widely used to sense teeth of a gear, timing belt wheel even bolt head, key-ways.
