Frequently Asked Questions
1. What is the 2510 series connector compatible with?
The 2510 series is fully compatible with industry-standard KK 254 (2.54mm pitch) connector systems. It can directly replace or mate with existing 2.54mm pitch wire-to-board connectors, making it ideal for both new designs and legacy system maintenance where supply chain simplification is a priority.
2. What pin counts and mounting options are available?
This series supports configurations from 2P up to 20P, covering a wide range of signal and power needs. Both Straight (180°, vertical) and Right Angle (90°, horizontal) through-hole mounting versions are available to fit various PCB layout and enclosure orientation requirements.
3. What is the electrical rating?
Rated for 3.0A AC/DC at 250V AC/DC, with a maximum contact resistance of 20mΩ Max, insulation resistance of 1000MΩ Min, and withstanding voltage of 1000V AC/minute. These specifications ensure reliable performance in both power and signal applications across consumer and industrial equipment.
4. What wire gauge does this connector support?
The connector accepts AWG #22 – #28 stranded wire, covering the most common wire sizes for internal wiring in appliances, control panels, and electronic equipment. The crimp terminals provide a secure gas-tight connection when used with the correct crimping tool.
5. How does the friction lock prevent accidental disconnection?
The housing features a friction lock mechanism that provides a secure tactile click when fully mated, preventing accidental disconnection due to vibration or cable tugging. This is critical for applications in appliances and industrial controls where connection reliability is essential.
6. What housing material and flammability ratings are available?
The housing is made of Nylon 66, available in both UL 94V-0 (highest flame retardancy) and V-2 options to match your application’s safety requirements and budget considerations. Contacts are Brass with Tin-plating as standard, with Gold-plating available on request.
7. What are the primary application areas?
Typical applications include home appliances (control boards for refrigerators, washing machines, air conditioners), industrial automation (PLC modules, sensors, motor driver interfaces), office equipment (internal wiring for printers, 3D printers, scanners), medical electronics (diagnostic equipment and patient monitoring systems), and power modules (low-power signal distribution and battery management).
8. Do you provide technical datasheets?
Yes. Request PDF technical drawings and detailed specifications using the form above (click “Download Specifications & Request a Quote”). Samples are also available for evaluation. Our engineering team can provide footprint recommendations and application support.
9. Can I get custom wire harness assemblies?
