Standard off-the-shelve and custom solutions – flat, durable and fully sealed.

Sensofoil® membrane potentiometers can be easily customized according to specific requirements. Their flat design of 0.5mm to 4mm makes them ideal for restricted installation conditions. The technical specifications respond to those of conventional precision potentiometers or even surpass these. Besides offering an attractive cost advantage, with custom designs they can be conveniently integrated into existing applications.

Based on customer requirements, Hoffmann + Krippner develops and produces in-house and supplies corresponding evaluation electronics and software if requested.

Sensofoil® membrane potentiometers are mostly used as actual value transmitters in medical technology applications, actuator systems, street car doors, test systems as well as various other applications. They transmit an analogue signal, proportional to the distance or angle to be measured. Sensors by Hoffmann + Krippner are also used as set point generator in input devices (e.g. hand held controls). Integration in control units allows for fully sealed surfaces according to IP65.

As an advantage of an analogue sensor, the accurate position signal is readily available even after a power outage.
