Next Generation Membrane Potentiometers NOVOTECHNIK
With its LFP line, the Novotechnik portfolio now also includes membrane potentiometers for linear position detection whose linearity and life expectancy closely match those of the known potentiometer standards. The traditional wiper of the membrane potentiometer is replaced with a membrane that is connected to the resistive track by way of a pin. Apart from this, the FR4 printed circuit board substrate technology permits the utilization of the standard procedures of potentiometer technology. Trusted screen printed resistive inks ensure high life expectancy (more than 25 million cycles). A subsequent linearization process provides excellent linearity over the entire product life (e.g., typically +/- 0.4% at a defined electrical travel of 50mm or +/- 0.3% at 500mm).
The membrane potentiometers are hermetically sealed, comply with the requirements of class IP67 ingression protection and are suitable for environmental temperatures up to a maximum of +257°F (+125°C). The component series is offered in standard lengths of 50 mm to 500 mm. In addition to linear models, rotary systems can be manufactured as well.
Applications range from integrated actuator systems in car and truck seats, window lifts, convertible car covers, and mirror systems to the positioning systems of solar panels, robotic systems, actuators, or for medical and space technology applications. The trouble-free function of the membrane potentiometers even in explosion-proof classified areas should also make them interesting options for many applications.
