Will shock and vibration resistance affect the electrical life of

Long-term vibration will cause loosening and fatigue of the mechanical structural parts of the relay. Looseness will change the matching relationship between the structural parts, resulting in

Performance of Relays and Protection Equipment under Vibration

Operating environmental vibration and shock may result in spurious operation of relays. Understanding cause and effect of vibration on relay performance is paramount to ensure reliable functioning of relays.

Effect of shock and vibration on relays

The vibration was caused by rotating machines or by transients such as passing trains or trucks. A majority of difficulties caused by shock occurred where relays were mounted on hinged panels.

Choosing relays for high-vibration environments

Contact bounce occurs when vibration causes relay contacts to make and break intermittently, leading to unreliable switching and potential system failures. This phenomenon directly impacts automation

Normally closed relay failing due to shock and vibration

We discovered that most relays like the one linked has a low shock rating and malfunctions pretty easily. Currently, due to large vibrations in a manufacturing environment, the
