PPS-11 Detection of the rotation of the magnetic body and the position
For encoder
For contactless switch
The principle of Pulse Perm Sensor 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.
