Designing for Extremes: Connector Selection in Harsh Environments
Harsh environments expose connectors to conditions like moisture, vibration, extreme temperatures, chemicals and EMI. Engineers must understand these hazards and select connectors designed to withstand them.
Corrosion: Salt water, oils and chemicals can damage connectors, but corrosion-resistant shells protect internals
Dust & moisture: Dust and moisture can damage connectors in outdoor or industrial settings, but IP-rated connectors with sealed designs protect against dirt and water
Vibration: Vibration can loosen and wear connections, but high-mating-force, locking connectors stay secure
Temperature extremes: Extreme temperatures can weaken connectors, but temperature-resistant materials like ceramic cores improve durability
Electromagnetic interference (EMI): High EMI can degrade signals, but shielded connectors maintain signal integrity
Radiation: Radiation can degrade connectors, but rad-hardened designs use shielded materials for protection
Pressure differentials: Pressure changes can break seals, but sealed connectors use locking mechanisms and airtight gaskets
