Linear Sensor

Features

・Linear voltage output against magnetic force.
・Linear voltage output against moving magnetic force.

・Detection and monitoring of magnetic vibrations.(0-100kHZ)

・Can be used in low or high temperatures.

 

linear example

*The sensor outputs voltage that is proportional to the changes of the magnetic flux denstiy.

*The output voltage saturates at about 40mT or more on both N-side and S-side.

Test data

Test data-1

・If the magnets are moved to the left or right under a certain gap, the linear output voltage can be obtained.

・The linear sensitivity can be modified by changing the gap size.

・A larger gap can be obtained against the same linear sensitivity with strong magnets.

linear test.1

Test data-2

・View the quadratic curve output voltage by changing the gap between the sensor and magnet.

・The gap size can be changed depending on the strength of the magnet.

・A 3.5 ~ 8.5 gap range is practical when using this magnet.

Precautions

・The circuit diagram must be observed to ensure a correct connection.

 A reverse connection and a short-circuiting output are strictly prohibited.
・When connecting an inductive load such as relay, be sure to use

 a freewheeling diode.

・When installing a switch, use the torque value designated for each switch.

・When handling / using the product, do not apply an excessive tension to

 the cable connection part.
