Industrial Connector Selection: 5 Core Points

1. Electrical Performance is the Foundation

1) Voltage/Current: The rated value must be higher than the actual value of the equipment (e.g., for equipment with 380V/50A, a 600V/60A grade connector is recommended) to prevent overheating and burnout.

2) Contact Resistance: Prioritize low-resistance products with <5mΩ to reduce power loss, suitable for long-distance/high-current scenarios.

3) Insulation Resistance: Must meet the standard of >10GΩ to ensure electrical isolation and prevent leakage and signal interference.

2. Environmental Adaptability Determines Durability

1) Temperature Range: Cover the operating environment (choose 200℃-resistant models for high-temperature areas, and models that work normally at -55℃ for low-temperature areas) to avoid material hardening and poor contact.

2) Protection Class (IP): Use IP65 for indoor dry environments, and IP67/IP68 for outdoor/humid environments (e.g., IP68 for marine equipment).

3) Chemical Protection: For chemical industry and similar scenarios, select acid- and alkali-resistant materials (such as PPSU material compliant with IEC 60695-2-11).

3. Mechanical Performance Ensures Stability

1) Insertion/Extraction Lifespan: Choose models with ≥5000 cycles for general scenarios (e.g., M12 connectors); higher-lifespan models are required for equipment that needs frequent maintenance.

2) Locking Mechanism: Use threaded locking for vibration-prone environments to prevent loosening; use bayonet/push-pull locking for scenarios requiring quick assembly/disassembly (with slightly weaker anti-vibration performance).

4. Size and Installation Must Be Compatible

1) Space Constraints: For compact equipment, select miniaturized connectors to avoid affecting the layout of other components.

2) Installation Method: Panel-mounted type for easy maintenance, cable-mounted type for connecting different cables, and PCB-mounted type for direct soldering to circuit boards—choose based on needs.

5. Cost Requires Comprehensive Consideration

1) Initial Cost: Do not blindly choose low-priced products; prioritize cost-effective options that meet performance requirements.

2) Lifecycle Cost: Modular designs may have higher initial costs, but they are easier to maintain and reduce equipment downtime, making them more cost-effective in the long run.
