Non-contact potentiometer Murata

The semiconductive reluctance elemental device (single crystal InSb) of high sensitivity was designed for the noncontact potentiometers.
Excellent characteristics by matching with the magnetic circuitry are exhibited.

There is the following advantage because it is the contact-less structure that a magnet was combined with the reluctance elemental device unlike slide wire potentiometer.

- Long life time because a resistor isn't worn away.
- Low torque because a shaft is held by the ball bearing.
- Mechanical response is excellent and electric response exceeds the mechanical response fully.

The angle detection of ± 50° is possible.

LP05M series is suitable for the high reliability use because a temperature compensation circuit is built in.

THose potentiometer are used for :

- Paper thickness measurement for ATM and OCR.
- String tension or Tape tension controller
- Angle measurement of valve
- Level detection of fluid
- Rotation angle measurement of servomotor
