European Market Leader in Complex Input Systems Present Next Generation of Ultra-Thin Membrane Potentiometer

Peachtree City, GA (May 27, 2009) - US based German company Hoffmann + Krippner to introduce next generation of membrane potentiometer with Sensofoil Hybrid® at the 2009 Sensors Expo & Conference at the Donald E. Stephens Convention Center in Rosemont, IL on June 8 -10th, 2009.

H+K's potentiometer technology includes various field applications and exemplary utilizations in array of industries:

o Automotive: Sensofoil® can control and are not exclusively limited to the convertible hood or the electrical seat adjustment.

o Medical: Used in life-saving systems and technologies. Sensofoil® is used as input system (an alternative to knobs) or also to determine accurate values (i.e. within pumps or in operating tables).

o Aviation: Sensofoil® can be used to determine the position of movable business and first class seats (memory function) and is the perfect solution for input systems such as seat control units.

Not exclusively limited to the aforementioned industries, H+K's Sensofoil Hybrid® technology is also utilized in door systems, portable devices, robotic systems, as well in the food processing industry.

Protected by a highly flexible metal bond, Sensofoil® Hybrid potentiometers avoid dents during longer periods of inactivity and the temperature range is also enhanced.

Standard sizes can be delivered from stock and individual Sensofoil Hybrid® elements can be developed with customized designs, coordinated to suit the specific applications of the customers. H+K offers smaller and medium-sized runs and also offers inexpensive, flexible options and direct contact with the developer.

Development, engineering, production and inspection based on individual parameters all takes place at Hoffmann + Krippner in Germany. This can include evaluation electronics and software upon request.

Product Features:

o precise evaluation thanks to analogue technology

o can be integrated into membrane keyboards or front panels of devices

o actuation can be performed by a person or a grip

o mature technology, already in use in thousands of medical engineering applications

o compelling price/performance ratio

"Our next-generation Sensofoil Hybrid® membrane potentiometer features a technology and quality level unmatched by competitors and enables customers to replace conventional linear or rotary potentiometers which reduce the installation space. Our product is completely waterproof and offers attractive cost-saving options if compared to mechanical potentiometers," said Guido Woska, president of Hoffmann + Krippner US.
