With its M3000 series, Epcos has developed a temperature sensor with a PVC-free cable that contains no halogens, environmentally harmful plasticisers or stabilisers with heavy metals. This means that no corrosive or toxic gases are released in the event of a fire, and little smoke is produced. In addition, no dioxins hazardous to health are formed at the end of its lifecycle when the product is disposed of. The sensors already meet future specifications for restricting environmental hazardous substances in household appliances.
In temperature cycling tests, the M3000 series withstands a total of 50 000 cycles from -20 to +30°C in water as well as 1000 cycles from -40 to +80°C in air. The sensors also offer moisture resistance at temperatures up to 80°C. Their resistance drift is significantly below 2% after immersion in water at 80°C for 2000 hours and storage at 85°C and 85% relative air humidity.
In addition to refrigerators and freezers, the M3000 series is also suited to other applications such as floor heating systems.
