Small sensor – great technology
Small sensor – great technology
Promotech, Austria
Multi-functional housing components for sensors in automobiles are the automotive segment in which the Austrian family-owned company Promotech, based in Schalchen near Mattighofen, specializes. One example is a combined rain, light and moisture sensor for motor cars. The top part of its housing with a diameter of just 33 mm incorporates seven infrared rain detectors and two lenses to measure the ambient light level. A connection plug with insertion-molded metal contacts is an additional component integrated in the housing. A vertical 3-component injection molding machine from WITTMANN BATTENFELD with an ultra-compact configuration of the injection aggregates is used to produce this part.
“But in spite of all this complexity, our daily production practice furnishes the proof that we were on the right track with our concept, which is largely based on WITTMANN BATTENFELD’s experience in nano and micro injection molding.”
