Designing for Extremes: Connector Selection in Harsh Environments
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.
Environmental concerns & key design considerations
- 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
