Relay selection of environmental conditions

Mar 24, 2017

Climatic stress factors, mainly refers to the temperature, humidity, barometric pressure (altitude), coastal atmospheres (salt spray test), sand and dust, chemical gases, and factors such as electromagnetic interference. Consider the systems in various industries and general applicability of the natural environment, taking into account the particularity must be years of reliable operation, key parts of the system must be selected for their high insulation, high dielectric properties of sealed relay products. Because only the hermetically sealed relays with excellent tolerance to harsh environment for a long time, good electrical contact switching load capacity for stability, reliability, and stability.
