8FLP10A Linear-motion Potentiometer
|
|
|
Linear-motion Potentiometers are compact in size, light in weight and are capable of transforming mechanical linear movements into corresponding electrical variations. Easy to operate and handy, they are suitable for measurement of linear movements in various machinery and tools and displacements in linearly moving objects such as steering angles, numerical control tooling machines, robots, etc. The resistive element in this series is made of conductive plastic (FLP-A) which features high resolution, long life expectancy and excellent high speed tracking ability.

Notes:
1. In case of the potentiometer with special resistance values and special specifications, the above performances may change and therefore, please consult us in advance, separately.
2. As for operating temperature range. we can not guarantee that all values of performances can satisfy within this operating
temperature range.
3. The above values of performances based on each testing were measured after each testing completed, respectively, under
standard conditions. As for the values during testing and other values not mentioning in the above table, please ask us separately.
Special Note
When ordering on the requirement of special shaft length in case of our linear-motion potentiometers, especially models 30LP, 50LP, 8FLP and 15FLP series as standard version with front and rear shaft extension, please do not fail to specify the shaft length exactly when the shaft is completely pressed into the housing.
Example: In case of model 8FLP10A standard version
As you see from the above right drawing, please specify the exact length of L1 and L2 when the shaft is completely pressed into the housing.
In case of models with spring return device, the condition of spring returned is as right drawing and please specify the exact length of L1 and L2 when the shaft is completely pressed into the housing.
Our policy is to improve specification of our products continuously, so technical and production details can be changed without any notice.
