Common Types of Car Connector in the Automotive Market
Modern automotive wire harnesses use a wide variety of connectors. Each has a different role depending on its position in the system, level of exposure to elements, voltage requirements, and signal accuracy needs.
1.Pin Connectors are the most basic type and are used for everything from window control to dashboard lighting. They come in multiple formats (e.g., 2-pin to 16-pin) and offer quick plug-and-play functionality.
2.RF (Radio Frequency) Connectors are essential for modern cars. They handle high-speed signal transmission for systems like GPS, cameras, radar, infotainment, and ADAS. In these systems, low signal loss and EMI shielding are vital.
3.Waterproof Connectors are rated IP67 or IP68 and are commonly found in the engine bay, under the car, or anywhere water and dust could cause trouble. These connectors must seal tightly, even when exposed to temperature swings or pressure.
4.Sensor Connectors are smaller and designed to transmit precise data from devices like oxygen sensors, ABS systems, and temperature monitoring units. In these cases, even minor interference can cause system failure, so performance stability is critical.
5.High-Voltage Connectors are now widely used in EVs and hybrid systems. They support power delivery between battery packs, inverters, and electric motors—sometimes carrying more than 800V across long cables.
6.FPC/FFC Connectors are found in interior systems where space is tight, such as infotainment screens, instrument clusters, or dashboard components. These lightweight connectors are used in combination with flexible printed circuits.
Each type serves a specific purpose and must meet environmental, thermal, and electrical standards for long-term use.

The Advantage of Using the Right Car Connector
Choosing the right car connector is about more than just a part number—it directly affects system safety, cost, and long-term stability.
A high-quality connector improves vehicle reliability by:
1.Reducing wiring errors and misalignment
2.Preventing signal interference in sensitive systems
3.Withstanding heat, vibration, and harsh weather
4.Supporting faster installation on automated lines
5.Simplifying diagnostics, maintenance, and repair
For example, a waterproof connector in a wheel-speed sensor must work after years of exposure to water, snow, and road salt. A weak or poorly sealed connector may lead to sensor failure and ultimately trigger a safety warning or even brake malfunction.
At JDT, our car connectors are tested to meet such requirements, providing not just functionality—but confidence.
Car Connector Material Grades and Specifications
Connector performance starts with the materials. At JDT Electronic, we use premium-grade plastics and metals selected for their proven performance in harsh automotive conditions.
For housing, we rely on PA66 (Nylon 66)—a strong thermoplastic with excellent heat resistance and mechanical strength. It’s ideal for standard connector shells exposed to engine heat.
In waterproof connectors, we use PBT reinforced with glass fiber. This adds strength, dimensional stability, and resistance to chemicals and water exposure. Combined with robust seal designs, this ensures excellent performance in wet, dirty environments.
Terminals are made from brass or phosphor bronze, ensuring high electrical conductivity and resistance to corrosion. Proper plating ensures stable long-term current flow and mechanical contact.
We also use silicone or EPDM rubber for seals and gaskets. These materials remain elastic and sealing-capable even when temperatures drop below freezing or exceed 100°C.
All materials are certified to meet international safety and environmental standards:
1.IP67/IP68: Water and dust resistance
2.ISO 16750 / IEC 60529: Mechanical and environmental stress
3.UL94 V-0: Flame retardancy for plastic parts
4.RoHS / REACH: Chemical safety for global export
Case Example: A German EV maker approached JDT for custom high-voltage waterproof connectors that could operate from -40°C to +120°C. Using PBT with 30% glass fiber and an IP68-rated sealing structure, we helped reduce their connector failure rate by 38% over six months of field testing.
