• Environmental Resistance:

  • Operating temperature: -55°C to +125°C 

  • Humidity resistance: 95% at +40°C 

  • Vibration resistance: 10-2000Hz at 196m/s² 

  • Shock resistance: 735m/s² 

• Electrical Performance:

  • Contact resistance: ≤10mΩ 

  • Insulation resistance: ≥5000MΩ 

  • Dielectric withstand voltage: 800V 

  • Rated current: 3A 

• Mechanical Durability: 500 mating cycles 

Primary Applications

Selection Considerations

When choosing J30J series connectors, consider:

1. Contact Configuration: Ensure proper gender (ZK for socket, TJ for plug) and pin count match requirements 

2. Mounting Style: Select straight (N), right-angle (W), or cable mount based on installation constraints 

3. Locking Mechanism: Choose appropriate lock type (P-series for vibration resistance) if needed 

4. Environmental Requirements: Consider temperature, humidity, and vibration specifications 

5. PCB Compatibility: Verify grid spacing (1.27×2.54mm standard or 1.27×1.1mm for some variants)
