Product Description

Our connectors integrate dual-beam or multi-point contact systems with high spring force to maintain a secure connection under dynamic conditions. Advanced locking mechanisms prevent disengagement due to mechanical shocks, while terminal position assurance (TPA) features ensure consistent mating integrity. Using low-friction coatings on mating surfaces reduces insertion force while maintaining stable electrical contact. 

Corrosion Resistance

500+ hours in salt spray (ASTM B117, IEC 60068-2-52)

EMI Shielding

Multi-layer conductive coatings, metal-plated polymer housings, and 360° shielded terminations

Mounting Options

PCB mount, panel mount, bulkhead, snap-in, and screw-lock configurations

Compliance Standards

ISO 19642, USCAR-2, IEC 60664-1, RoHS, REACH, UL 94

Custom Features

Overmolded strain reliefs, multi-pin configurations, color-coded housings, locking mechanisms

UV Resistance

UV-stabilized thermoplastics for long-term outdoor exposure (ISO 4892-2)

Fire Resistance Rating

UL 94 V-0 (self-extinguishing, high flame resistance)

Chemical Resistance

Resistant to fuels, hydraulic fluids, coolants, and industrial solvents (ISO 16750-5)

Thermal Expansion Tolerance

Engineered for minimal expansion under extreme heat (low CTE materials like LCP and PPS)

Dynamic Load Testing

Passed 1 million+ mating cycles under full electrical load (per IEC 60512-5-2)

Precision Tolerances

±0.05mm for critical dimensions, ±0.1mm for non-critical areas

Technical Advantages

Under-hood applications expose connectors to temperatures exceeding 150°C, requiring materials with high thermal resistance and low expansion coefficient. Our connectors utilize polyphenylene sulfide (PPS), liquid crystal polymers (LCP), and high-temperature-rated PBT compounds, ensuring stability across wide thermal gradients. Metal-plated polymer housings enhance heat dissipation, preventing thermal degradation of internal components. Contact interfaces employ beryllium copper (BeCu) and phosphor bronze alloys with gold or silver plating to prevent oxidation at elevated temperatures. Thermal expansion differentials are mitigated through precision-molded interfaces that maintain consistent engagement force, reducing the risk of open circuits due to material deformation.

Automotive connectors must resist water, dust, oil, and aggressive chemicals, particularly in chassis, powertrain, and underbody applications. Our solutions incorporate multi-layer sealing architectures with fluoro silicone elastomers to provide IP67 and IP69K-rated ingress protection. Hydrophobic coatings on connector surfaces repel moisture and contaminants, preventing premature corrosion. Terminal plating technologies, including electroless nickel-phosphorus and immersion tin, offer enhanced resistance to galvanic corrosion in high-humidity environments. Overmolded strain reliefs ensure that cable-to-connector transitions remain mechanically robust, preventing water ingress through capillary action.

Automotive connectors

High-Voltage Isolation and Safety in Electric Vehicle (EV) Systems

Electric vehicles and hybrid platforms operate at voltages exceeding 400V, necessitating specialized connectors with robust insulation and arc-prevention mechanisms. Our high-voltage connectors feature creepage and clearance distances exceeding IEC 60664-1 standards, reducing the risk of dielectric breakdown.

Modern vehicle architectures demand high-density, lightweight connectors without compromising electrical performance. Our ultra-miniature connector systems employ high-strength aluminum alloy housings with electroless nickel plating, achieving weight reduction while maintaining mechanical durability. High-pin-density arrangements leverage staggered terminal layouts and multi-layer contact arrays, optimizing space efficiency.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure high-current carrying capacity in automotive power connectors?

Frigate utilizes precision die-cast copper and aluminum alloy terminals with low contact resistance to handle high current loads efficiently. Electroless nickel and silver plating improve conductivity and minimize thermal rise. Connector designs include multi-contact interfaces to distribute current evenly, preventing localized heating and degradation. 

What sealing technologies does Frigate use for automotive connectors in harsh environments?

Frigate employs multi-layer fluoro silicone and EPDM seals to achieve IP67 and IP69K ratings for water, dust, and oil resistance. Connectors feature over-molded strain reliefs to prevent ingress through cable entry points. High-precision die-cast housings ensure tight tolerances, eliminating micro-gaps that can lead to seal failure over time. 

How does Frigate prevent galvanic corrosion in multi-metal connector assemblies?

Frigate applies selective plating techniques such as tin-over-nickel or gold-over-palladium to minimize galvanic potential differences between dissimilar metals. Zinc and aluminum die-cast housings are coated with chromate conversion layers to enhance corrosion resistance. Additionally, connectors incorporate sacrificial anode coatings in extreme environments to extend service life. 

How does Frigate ensure high-speed data integrity in automotive Ethernet connectors?

Frigate designs impedance-controlled connectors using low-loss dielectric materials like LCP and PTFE to support multi-gigabit data rates. Shielded twisted-pair (STP) and coaxial architectures minimize EMI and crosstalk. Die-cast shielding enclosures are integrated with low-inductance grounding paths, reducing noise interference in high-speed automotive networks. 

How does Frigate improve connector robustness for EV high-voltage applications?

Frigate employs arc-resistant die-cast copper alloy contacts for EV connectors with high-voltage insulation barriers, meeting IEC 60664-1 standards.
