PPS-03 Detection of the rotation of the magnetic body and the position
For encoder
For contactless switch
The principle of Pulse Perm Sensor r has applied the large Barkhausen effect. The phenomenon which the field in the compound magnetic wire which carried out non-conventional machining reverses rapidly by an external magnetic field is used. The field reversed rapidly is changed and outputted to pulse form voltage inside a compound magnetic wire with the coil prepared in the wire perimeter. Therefore, a power source is not needed for sensor actuation. The impulse wave outputted is about 20 microseconds in pulse width in more than voltage 2V.
* The detail about Pulse Perm Sensor should look at here.

Description

Output occurs with a non-power source
The output of the same magnitude is acquired regardless of the inversion rate of an external magnetic field
For a simple configuration, it is strong to temperature-and-relative-humidity change, and we secure dependability over a long period of time
The lineup of the model from which die length differs according to an application is carried out

Precautions

- Since change arises in output when the magnetic field which is not a par magnet is added to a sensor, be careful of the service condition of Pulse Perm Sensor .
- Please do not arrange a magnetic substance near Pulse Perm Sensor.
- This specification and shape may be changed without an advance notice.
