Product Description
This 3 Pin Round Male Power Connector is a compact electrical connector designed for stable DC power and low-frequency signal transmission. The connector uses three Ø0.63 mm round pins arranged on a circular pitch and terminated by through-hole solder tails, making it easy to mount on a PCB or integrate into a custom cable assembly. Gold-plated contacts over a nickel base deliver low contact resistance and excellent corrosion resistance, ensuring reliable performance over repeated mating cycles in harsh environments. The high-temperature thermoplastic housing provides mechanical strength and electrical insulation, while the cylindrical shape allows easy alignment with the matching female connector. Customization is available for pin length, plating, housing color, and complete wire-to-board or wire-to-wire harness solutions to match different device designs.

Applications
DC power connection for handheld devices, miniature fans, and wearable products
Interface between battery packs and control PCBs in consumer or industrial equipment
Signal and power connector for LED light modules and small controllers
Compact power connector in automotive electronics, medical devices, and instrumentation
Custom magnetic or circular harness solutions where a 3-pin low-voltage connector is required
Always mate this male connector with a compatible 3-pin female connector designed for the same pitch and diameter.
Do not exceed the specified voltage and current ratings; verify the final rating according to your application and selected materials.
When soldering the pins to a PCB, follow recommended reflow or hand-soldering profiles to avoid damage to the plastic housing.
Keep contacts clean and free from dust, flux residue, or moisture to maintain low contact resistance and stable signal transmission.
Avoid excessive mechanical stress, twisting, or pulling on the connector after soldering; provide strain relief through housing design or cable clamping.
For outdoor or high-humidity environments, consider potting, sealing, or using protective housings to improve overall system reliability.
