Background
High-current connectors serve massive user bases in power transmission. When selecting them, focus on these four non-negotiables:
The 4 Critical Selection Criteria
01. High Current Capacity + Low Temperature Rise
These connectors routinely handle 50A-100A+ currents. Beyond amperage ratings, evaluate:
✓ Conductive materials: Copper alloy cores with sufficient cross-sections
✓ Low contact resistance
✓ <30K temperature rise to prevent overheating
✓ Minimal wear after repeated mating cycles
02. High Protection & Environmental Resistance
Industrial/outdoor applications demand:
✓ IP68/IPX9K ratings for dust/water resistance
✓ -40°C to +120°C operating range
✓ Corrosion operating range
✓ Corrosion/UV resistance
✓ UL94 V-0 flame retardancy
03. Safety First Design
High-current/high-voltage transmission requires:
✓ Unbreakable mating security against accidental disconnection
✓ Touch-proof terminals preventing finger contact with live parts (Many connectors overlook these critical safeguards)
04. Compact Footprint
Traditional high-current connectors (like IEC60309 plugs) are notoriously bulky IEC60309 plugs) are notoriously bulky. But innovative designs like CNLINKO’s DL28 prove miniaturization is possible:
✓ 50% smaller than IEC60309
✓ Full power in compact form
