High Temperature Cable Connector
High Temperature Cable Connector for Reliable Connections in Demanding Environments
High Temperature Cable Connectors are designed for cable connection applications where conventional connectors may be exposed to elevated temperatures, demanding operating conditions or limited installation space.
We provide different connector configurations for different cable and equipment interfaces.
High Temperature 4.3/10 Straight Coax Connector:A straight coaxial connector configuration for applications requiring a reliable RF/coaxial cable connection. Suitable for projects where connector interface compatibility and stable mechanical installation are key procurement considerations.
High Temperature 7/16 Straight Coax Connector:Designed for applications using 7/16 coaxial interfaces. The connector configuration can be selected according to cable construction, equipment interface and required operating conditions.
High Temperature Resistant N Straight Coax Connector:A high-temperature-resistant N-type coaxial connector for applications requiring a widely used RF interface together with resistance to elevated operating temperatures.
Temperature Resistance Is a System Requirement
In high-temperature applications, connector reliability depends on the complete material system.The main components that should be evaluated include:
Contact Material:Contact material and plating influence electrical conductivity, contact stability and resistance to environmental degradation.
Housing Material:The connector housing must maintain its mechanical properties under the intended temperature range.
Insulation Material:Insulation performance needs to remain stable under the specified thermal and electrical conditions.
Sealing / Over-Mold Material:Where waterproof or environmental protection is required, the sealing material and over-mold structure must be compatible with the application temperature and exposure conditions.
Application
Telecommunications
High temperature cable connectors are used in communication equipment and RF systems. The existing range includes 4.3/10, 7/16, and N type coaxial connectors, allowing selection according to the equipment interface.
Industrial Equipment
Suitable connector configurations can be evaluated for equipment exposed to elevated temperatures, vibration, or demanding installation conditions. Selection should be based on actual temperature, electrical load, and environmental exposure—not application name alone.
Automotive Systems
Automotive applications involve elevated temperatures, vibration, restricted space, and changing conditions. Selection should consider temperature rating, locking structure, cable compatibility, and mechanical stability together.
Electrical & Electronic Equipment
For equipment requiring compact and reliable cable connections, confirm connector configuration, electrical specifications, and protection requirements before mass production.
Selection guide
|
Need |
Best Fit |
Why |
|
High power + ultra-low PIM, outdoor site |
7/16 straight |
Largest coupling, best PIM/power class |
|
Dense equipment, limited space, low PIM |
4.3/10 straight |
Smaller flange, low-PIM, easier packing |
|
General RF, test/broadcast, cost-sensitive |
N straight |
Versatile, wide frequency use |
|
Hot climate / enclosed transmitter |
Any, but check derated range |
Apply ambient + self-heating derating |

Outdoor / washdown |
Sealed version of the above |
Temperature-rated seal + IP |
Material & construction for heat
Dielectric
PTFE or stabilized variant for low loss and dimensional stability when hot.
Body & contact
Brass body, nickel (or gold) plating; contact gold or silver alloy depending on PIM/power target.
Seal
Silicone / temperature-rated O-ring that stays elastic across the rated range.
Coupling
Threaded (7/16, N) or screw (4.3/10) — torque to spec; over-torque distorts the interface and worsens PIM.
Derate for self-heating: Subtract RF I²R rise from the ambient rating; size the connector to the derated number, not the catalog figure.
Seat once, correctly: Proper torque and a clean, undamaged ferrule; a mis-seat is where heat and PIM concentrate.
Avoid mixed metals in the hot zone where galvanic corrosion can accelerate at temperature.
Re-torque policy: For sites with large daily thermal swing, a scheduled re-torque check catches creep before it becomes a fault.
Custom High Temperature Cable Connector
Standard connectors may not always match the cable, equipment interface, or environmental requirements of an engineering project. Customization can be discussed for:
Connector interface, cable type and cable diameter, connector structure, contact configuration, housing material, contact material and plating, cable length, termination method, locking structure, waterproof/sealing configuration, labeling and identification, customer packaging, and private-label requirements.
Quality Verification Before Shipment
Our quality approach focuses on the parameters that directly affect connector performance:
Dimensional Verification
Connector dimensions and mating interfaces are checked against the specified design.
Mechanical Verification
Connector assembly and locking structures are checked to ensure proper installation and retention.
Electrical Testing
Applicable electrical characteristics such as contact resistance and insulation resistance can be evaluated according to the product specification.
Environmental Performance
Where required, environmental and temperature-related testing can be arranged according to the agreed product specification.
