PFORZHEIM, Germany - AMI DODUCO, a Technitrol (NYSE:TNL) Company, recently presented three publications on contact technology at the 18th Albert Keil Contact Seminar in Karlsruhe, Germany.
In the first, “The influence of the bonding area of contact tips on contact erosion,“ Dietmar Späth, Head of the Application Laboratory at AMI DODUCO, examined the effect of the contact bonding area on the service life of the end product. His results showed that using resistance soldering, a 70% bonding area provides effective insurance against premature contact erosion. Significantly shortened service life occurs when bonding areas are less than 40%. Bonding areas had no observable effect on the temperature rise in the switches tested.
In two specific applications, AMI DODUCO presented results of investigations into environmentally friendly, cadmium-free contact materials. Oliver Lutz, technical customer service officer at AMI DODUCO, found that silver/zinc oxide 92/8 with a silver tungstate (Ag2WO4) additive proved especially suitable for light switches, fulfilling all of the standard performance requirements.
Also, AMI DODUCO Pforzheim and the Ruhrtal unit of Siemens collaborated in a test of silver/tin oxide (Ag/SnO2) with molybdenum additives in high-voltage circuit breaker applications. This material proved to be not merely equivalent in performance to silver cadmium oxide, but technically superior.
The biennial Albert Keil Contact Seminar is a leading forum on contacts and switches used in a variety of applications by switchgear manufactures, suppliers and sub-contractors.
