Ingression Protection for Solenoids
Ingression protection is a commonly requested solenoid feature. As dirt, dust, moisture, and other foreign objects accumulate in a solenoid, the performance and life cycle are dramatically reduced. There are several methods to combat ingression, but before choosing the correct solution it is important to understand the degrees of protection available. International Protection (or IP) ratings are an industry standard used to measure the effective limits of ingress protection for electronic devices. An IP rating is commonly expressed as IPXY, where X represents the number given to the level of protection from solids and Y represents the number given to the level of protection from liquids and vapors.
