Theben uses cadmium-free contacts made from AgSnO2 materials
Cadmium oxide was thought to have been the ideal contact material for high switching currents. In the meantime, it is forbidden according to the RoHS guideline - where there are exceptions for electrical switching contacts. Theben had already changed to the environmentally friendly AgSnO2 material at the turn of the millennium.
Diese bieten vergleichbar gute, teilweise sogar bessere Kontakt- und Schalteigenschaften, wie h枚here Abbrandfestigkeit, erh枚hte Verschwei脽resistenz und eine deutlich geringere Neigung zur Materialwanderung bei Gleichstrombetrieb.
