3.2 Medical and Diagnostic Equipment

  • Diagnostic Instruments: Equipment requiring sealed connectors for cleaning and sterilization cycles
  • Patient Monitoring: Bedside monitors and portable devices in clinical environments

3.3 Outdoor and Mobile Equipment

  • Field Communication Systems: Portable radio and data link equipment exposed to weather
  • Transportation: Vehicle-mounted instrumentation for environmental monitoring
  • Military and Defense: Ruggedized connectors for mobile field equipment (non-critical applications)

4. Common Questions (FAQ)

Q1: What does the MEG.1K.307.CLL-J model number indicate?

MEG denotes the series and type (1K series female receptacle), 307 indicates 7 contacts in shell size 3 (1K), and CLL-J specifies the termination and accessory configuration. The J suffix indicates a specific variant with particular contact and plating options.

Q2: Is the MEG.1K.307.CLL-J interchangeable with other brands?

Yes, the 1K series connector is designed for interchangeability with connectors of the same type from other manufacturers. For specific compatibility verification with your existing system, contact our engineering team at [email protected] with your application details.

Q3: What testing should be performed after receiving 1K series receptacles?

We recommend the following checks upon receipt: (1) Visual inspection of contacts and sealing surfaces, (2) Mating test with the corresponding plug to verify latching and alignment, (3) Continuity test on all 7 pins, (4) Insulation resistance test between adjacent contacts. The customer who ordered 100pcs confirmed all units passed their incoming inspection without issues.

Q4: How does the 1K series compare to the 0K series for watertight applications?

The 1K series offers a larger shell size accommodating up to 19 contacts, while the 0K series is more compact with up to 7 contacts. Both provide IP68 sealing. The 1K is preferred when higher pin counts or larger wire gauges are needed, while 0K suits space-constrained applications — see 0K series product page for details.

Q5: What is the typical lead time for 1K series connector orders?

Standard orders typically ship within 20 working days. Larger quantities (500+ pcs as in this repeat order) may require up to 40 working days. Rush orders and express shipping options are available — contact our sales team for confirmation.
