WNRE 2+1+7 Industrial Connector:Tested For 3000 Mating Cycles
| Circuit Type | Specification | Performance Benefit |
| Main Circuit | 6.0mm2 terminals | 50A continuous current (ΔT≤50°C) |
| Secondary Circuit | 2.5mm2 terminals | Independent auxiliary power |
| Signal Lines | 0.25mm2 shielded cables | EMI-resistant data transmission |
The WNRE 2+1+7 Series Heavy-Duty Connector adopts an innovative triple-circuit architecture, perfectly addressing the needs of high-power transmission and signal control in industrial environments. The main circuit features 6.0mm2 large-section terminals capable of stably carrying 50A continuous current, with temperature rise controlled within 50°C under full load testing to prevent overheating during prolonged operation.
Military-Grade Reliability Performance
Rigorous testing verifies the 2+1+7 Series' exceptional electrical performance. Contact resistance remains stably below 1.5mΩ (4-wire measurement), effectively reducing energy loss.
With 1500V AC withstand voltage ensuring no breakdown between main circuits, insulation resistance consistently exceeds 10MΩ. The product demonstrates outstanding environmental adaptability, maintaining all performance metrics without degradation through consecutive exposure to 85°C high temperature, -10°C low temperature, and 85°C/95%RH damp heat conditions.
After 48 hours of neutral salt spray testing, contact terminals retain excellent conductivity, proving superior corrosion resistance.
Mechanical Durability Breakthroughs
| No. | Test Item | Method | Requirement | Notes |
| 1 | Mating cycles | 3000 cycles,150mm/min | Conductivity OK after 5000 cycles | |
| 2 | Screw durability | 10N·m (Torque), 8 cycles | Thread integrity maintained | Electric screwdriver required |
| 3 | Flex test | ±45°, 1500 cycles | No disconnection/debonding | |
| 4 | Drop test | -10°C±2°C, 24h | No damage |
The series achieves significant breakthroughs in mechanical performance. After 3000 standard mating cycles (150mm/min speed), all electrical parameters remain fully compliant.
The innovative threaded locking mechanism withstands 10N·m of repeated tightening operations, maintaining structural integrity through 8 complete installation/removal cycles. The product also passes ±45° bending tests for 1500 cycles, verifying reliable connection capability in vibrating environments.
