In industry, resistors have to work safely under difficult environmental conditions for many years. Apart from the permissible temperature range, the chemical load is a limitation of use. This includes resistance to pollutants such as vapours, gases, coal dust, oil or brake abrasion. In addition, the penetration of moisture and the smallest foreign bodies must be prevented for reliable function, and physical effects such as vibrations or oscillations must not have a negative influence.
The REOhm resistors of the BW 15X series have been specially designed for these environmental influences. Their special design ensures maximum protection against mechanical, chemical or biological influences and enables a high level of functional reliability as well as a long service life with simultaneously low-noise operation.
