Cable Compatibility
RG141 Coaxial Cable: The connector is specified for RG141 cable assemblies, making it suitable for RF connection systems using this cable type.
RG380 Coaxial Cable: RG380 is also listed as a compatible cable, allowing the same connector series to be used across specified cable assemblies.
Cable Selection: Cable type should be confirmed against the connector version before bulk purchasing, particularly when RG141 and RG380 assemblies are used in the same project.
Assembly Matching: Cable construction and connector termination must be matched to the applicable connector specification to ensure correct mechanical and electrical assembly.
Environmental Performance & Applications
Temperature Range: Suitable for cable connection points operating within the specified -40°C to +85°C temperature range.
Thermal Application Matching: Intended for RF cable assemblies where the connector and coaxial cable need to be selected together according to the required operating temperature.
Combined Environmental Conditions: Suitable for installations where elevated temperature occurs together with outdoor exposure, dust, or moisture conditions.
Material & Construction
N-Type Straight Configuration: The connector uses a straight N-type configuration for direct integration with compatible coaxial cable assemblies.
Sealed Construction: The connector is specified with an IP67 sealing class, providing a defined environmental protection level for installed cable connections.
Insulation System: The insulation system is specified with an insulation resistance of ≥5000 MΩ, supporting electrical isolation between the connector conductors.
Compliance-Controlled Materials: RoHS compliance is specified for the finished connector, providing a material compliance criterion for procurement and incoming inspection.
Termination & Installation
Cable-Specific Assembly: Installation should follow the termination requirements of the applicable RG141 or RG380 cable and connector configuration rather than using a common stripping or assembly procedure for both cables.
Connector Matching: Confirm the connector model against the cable type before assembly to avoid dimensional or termination incompatibility.
Electrical Inspection: After termination, center and outer contact resistance can be checked against the specified limits of ≤1.00 mΩ and ≤0.25 mΩ respectively.
Environmental Installation: For applications requiring the stated IP67 protection, the connector should be assembled and installed according to the applicable sealing requirements of the connector configuration.
Packaging & Bulk Supply
Unit Packaging: Individual connectors are packaged with protective caps on mating interfaces to prevent thread damage and dust accumulation prior to installation.
Bulk Quantities: Available in manufacturer-direct volume packaging tailored for OEM assembly lines and large-scale infrastructure projects.
Traceability: Each batch includes standard labeling indicating part numbers, manufacturing specs, and RoHS compliance status for quality control.
Custom Shipping Options: Shipping cartons are reinforced to protect precision RF interfaces from impact damage during international transit.
FAQ
Q: What is the minimum order quantity (MOQ) for custom plating or branding?
A: MOQs typically start at 1,000 units per batch for non-standard production runs.
Q: Can the factory provide material test reports or certificates for RoHS compliance?
A: Yes, lot-specific documentation is available upon request during order confirmation.
Q: What is the typical lead time for orders of 5,000 units or more?
A: Standard production cycles range from 15 to 25 business days based on current scheduling.
Q: Are pre-terminated cable assemblies available, or are connectors sold separately?
A: Both loose components and fully tested custom cable assemblies can be ordered.
Q: How are connectors protected against thread damage and pin distortion during transit?
A: Units are individually capped and packed in compartmentalized trays or partition grids.
Q: Are 3D STEP files or mechanical drawings available for customer designs?
A: Yes, blueprints and STEP files can be requested through the sales team.
Q: What is the policy if incoming inspection reveals VSWR deviations?
A: Non-conforming lots identified during incoming quality control are eligible for technical analysis and replacement under standard commercial terms.
