Method for Regulating the Linearity
With rated voltage applied between terminals 1 and 3, the straight line which
connects the measured output values VB and VA at specied reference positions
B and A is assumed to be an ideal straight line, so that deviation against the ideal
straight line when the voltage applied between terminals 1 and 3 is assumed to be
100％ can be expressed as a percentage.

〔Total Resistance〕
The total resistance, with the shaft （lever） placed at the end of terminal 1 or 3, shall be determined by
measuring the resistance between the resistor terminals 1 and 3 unless otherwise specied.
〔Rating Voltage〕
The rating voltage corresponding to the rated power shall be determined by the following equation. When the
resulting rated voltage exceeds the maximum operating voltage of a specic resistor, the maximum operating
voltage shall be taken as the rated voltage.

1. Cleaning sensors should not be attempted.
2. Type of solder to be used Use cream solder that contains 10 to 15 %wt flux.
3. Number of solder applications - apply solder only once
4. Recommended reflow conditions
1. When using an infrared reflow oven, solder may not always be applied as intended.
Be sure to use a hot air reflow oven or a type that uses infrared rays in combination with hot air.
2. The temperatures given above are the maximum temperatures at the terminals of the sensor when employing a hot air
　 reflow method. The temperature of the PC board and the surface temperature of the sensor may vary greatly depending
　on the PC board material, its size and thickness. Ensure that the surface temperature of the sensor does not rise to 250℃
　 or greater.
3. Conditions vary to some extent depending on the type of reflow bath used. Be sure to give due consideration to this prior to use.
