Rotary position sensor 8820

potentiometeranalogmetal

Potentiometric angle of rotation sensor - 8820 As an angle sensor that is both accurate and economical, this rotary potentiometer is suitable for all types of analog angle measurement up to 350°. Typical fields of application include: -Position feedback in servo-systems -Pendulum weighing machines -Cam and butterfly flap positions -Jockey roller controllers -Measuring the tension of threads and tape -Trigonometric measurements at joints The heart of the potentiometric angular displacement sensors is an extremely precise, low-wear resistor track made of plastic. Due to its high resistance to abrasion, the sensors are particularly suitable for measurements for the purpose of quality assurance in ongoing production, where a long service life and large numbers of rotations are required. The potentiometric angular displacement sensor uses a multi-finger slider system with precious metal contacts. This ensures good contact even when moving at high speed and in the presence of vibrations. The high-precision resistor tracks are pressed in a lasercontrolled process and are therefore remarkably flat. This provides ideal conditions for a long service life. The stainless steel shaft is supported by close-tolerance, low-friction, stainless steel ball bearings with double sealing discs. FEATURES: -Measuring range 0° ... 350° depending on the model -Non-linearity from ± 0.5 % F.S. -Low torque -Continuous rotation possible -Exceptionally inexpensive -Options: IP65, non-linearity 0.1 % F.S.
