KTR auto-return series linear position sensors are designed for measurement of displacement under the condition of limited space. Anodized aluminium housing can contribute to nice appearance and super corrosion resistance. By adopting conductive plastic track inside, the product could run smoothly and have low-noise output signals.
All KTR sensors has groove for the mounting brackets to fasten it on the machine
This kind of transducer has the function of self-return through external spring so that there is almost no requirement to connecting mechanism, just keep touch with the target. MINUO could not only provide you with required linearity, but also any resistance you need, such as 5678Ω or 8765Ω.
Professinal Package: each sensor was packed in every
Cardboard tube
Product Characterist
1.Simple structure, small size, light weight, affordable, but with stable and high
precision quality.
2.Less impact generated by the environment (Such as temperature, humidity,
magnetic interfere etc).
3.Any function of input and output can be implemented.
4.Strong output signal, normally no need to additional amplifier.
5.Suitable for the condition which any optical rule or rotary encode can not be used.
6.Easily installing and maintaining.
7.Save mechanical costs about 30%
Output signal mode
| Output signal mode |
| A.Resistance: 1K,2K, 5K,10K,20K Ω |
| B.Current: 4-20mA |
| C.Power: 5V,10V,12V,24V |
| D.Related digital indicator: up-limit and bottom-limit setting function |
| (relay output, analogue, RS232/485 interface) |
Function Principle
First change the physical change of being measured target into the change of resistance,
then the change is orocessed via related measure circuic and device. Finally be displayed
or recorded. So we also called it electronic rule or digital position switch. It can be used in
a PLC control system for the frequenty conversion system, measuring the object distortion
etc, such as:controlling the travel of gas cylinder or oil cylinder, the positive &reversal-going change of the angle and so on. At same time, any position can be set as the start or stop point,
and give a feedback signal. It can replace limit switch, linear slippage rheostat, Linear Variable
Differential Transformer (LVDT)
