IGP Series
Using this potentiometer a maximum angular rotation of 3800° can be converted into a voltage proportional to the angle of rotation, through the medium of a conductive-plastic potentiometer.
This special "heavy-duty" version is designed to measure angular or linear displacement under the most difficult of enviromentat conditions. Simply yet robustly built, these units are suitable for use in all manner of industrial applications and engineering industry.
The cast housing is watertight. The single stage gearing is exceptionally backlash-free. Heavy-duty bearings allow for high axial loading on the shaft; gearwheels or even chain drives may be used directly drive the shaft.
Sealing is achieved through the use of a stepped bush whilst electrical connections are made via plug and socket mounted on the side of the unit.
Special features
- reduction gearing 3:1, 5:1, 10:1
- good linearity 0.1 % (standard)
- long life typically 100 x 106 movements
- mechanical rotation
- robust construction with 10 mm shaft
- Protection class IP 65

Metal Oxide Varistors are ceramic passive components made of zinc oxide sintered together with other metal oxide additives. They provide an excellent protective device for limiting surge voltages and absorbing energy pulses. Their very good price / performance ratio enables designers to optimize the transient protection function when designing the circuits.
Manufactured according to high level standards of quality and service, our Metal Oxide Varistors are widely used as protective devices in the telecommunications, industrial, automotive and consumer markets.

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
