In industrial settings, resistors must operate reliably for many years under challenging environmental conditions. Beyond the permissible temperature range, chemical exposure represents an operational limitation. This includes resistance, for example, to harmful substances such as vapors, gases, coal dust, oil, or brake dust. Furthermore, for reliable operation, the ingress of moisture and even the smallest foreign particles must be prevented, and physical impacts such as vibrations or oscillations must not have a negative effect.
The REOhm resistors of the BW 15X series have been specifically designed for these environmental conditions. Their special design ensures maximum protection against mechanical, chemical, or biological influences, enabling high operational reliability and a long service life with simultaneously low-noise operation.
