1. Product Overview: Standard Pitch and Flexible Right-Angle Design

The KH-A2541WR-10P is a 1×10P single-row, right-angle pin header with a standard 2.54 mm pitch. Also known as a 0.1-inch pitch, 2.54 mm is one of the most widely adopted connector pitches in the electronics industry, offering excellent compatibility with standard PCB layouts and mating connectors.

With 10 pins arranged in a single row, the KH-A2541WR-10P provides sufficient connection points while maintaining a compact form factor. It is particularly well suited for compact circuit modules requiring multiple signal or power connections in parallel.

One of the product's key design features is its 90-degree right-angle configuration. Unlike conventional vertical pin headers, the pins of a right-angle header extend parallel to the PCB after installation rather than perpendicular to the board surface. This design offers significant advantages in space-constrained applications. When internal device height is limited and there is insufficient clearance for a vertically mounted connector, the right-angle pin header allows connections to be routed horizontally along the PCB, effectively reducing the required vertical space and providing greater flexibility for compact electronic product design, such as slim smart devices and portable instruments.

2. Performance Specifications: Stable and Reliable for Mainstream Applications

The KH-A2541WR-10P delivers solid electrical performance for a wide range of electronic applications. It features a rated current of 3 A and a rated voltage of 250 V, making it suitable for signal transmission and low-power supply applications in most electronic devices. Whether used for board-to-board signal interconnection or module power delivery, the connector provides sufficient current-carrying capability for mainstream applications.

In terms of mechanical specifications, the product features a 6 mm mating pin length and a 2.54 mm insulator height. The 6 mm mating length provides sufficient insertion depth when mated with a compatible female header or socket, helping ensure secure engagement and reliable electrical contact. The 2.54 mm insulator height is consistent with the pin pitch, reflecting a standardized and uniform design.

The KH-A2541WR-10P operates over a wide temperature range of -40°C to +105°C, enabling it to accommodate demanding operating environments ranging from cold outdoor conditions to high-temperature industrial applications. Whether deployed in outdoor communication equipment during harsh winters or in industrial controllers operating continuously under heavy loads, the connector is designed to maintain stable electrical connectivity across a broad temperature range.

3. Materials and Manufacturing: Quality Materials for Long-Term Reliability

The KH-A2541WR-10P reflects Kinghelm's commitment to quality in both material selection and manufacturing processes. The product uses high-conductivity copper as the contact base material, combined with a corrosion-resistant plating treatment. The high-conductivity copper helps ensure efficient signal transmission with low electrical loss, while the protective plating enhances oxidation resistance and wear resistance. These characteristics are essential for maintaining low contact resistance and minimizing signal degradation over extended periods of use.

The product is manufactured under strict process controls to ensure consistent dimensions and pin coplanarity from batch to batch. This is particularly important for automated assembly and wave soldering processes. Precise dimensional control can help reduce soldering defects, improve first-pass yield, and enhance overall production efficiency.

The product complies with RoHS environmental requirements, helping meet environmental regulations in major global markets.

The KH-A2541WR-10P is supplied in bag packaging, with a single-piece gross weight of approximately 0.775 g. Bag packaging facilitates convenient handling, inventory management, and on-demand usage, making it suitable for R&D prototyping as well as small- and medium-volume production.

4. Applications: Versatile Connectivity Across Multiple Industries

With its standardized pitch, flexible right-angle configuration, and reliable electrical performance, the KH-A2541WR-10P can be used across a wide range of electronic applications:

• Consumer Electronics: In smartphones, tablets, smart wearables, and other products where internal space is highly constrained, the right-angle configuration helps reduce vertical clearance requirements and enables more flexible component placement within compact enclosures.

• Industrial Control: In PLCs (Programmable Logic Controllers), industrial instruments, variable-frequency drives, and other industrial equipment, the pin header can be used for board-to-board or module-to-module interconnection, providing stable signal transmission in demanding environments involving elevated temperatures and mechanical vibration.

• Automotive Electronics: Automotive infotainment systems, body control modules, navigation systems, and other automotive applications impose stringent requirements on connector temperature resistance and mechanical reliability. The KH-A2541WR-10P's wide operating temperature range and secure mechanical design make it a reliable interconnection option for such applications.

• Communication Equipment: In routers, base-station equipment, optical communication modules, and other communication products, the pin header can be used to interconnect power and signal boards, helping meet the demanding connectivity requirements of communication systems.

• Test and Measurement Instruments: In multimeters, oscilloscopes, testing equipment, and other instruments, the pin header can serve as a pluggable interconnection point between internal circuit modules, facilitating assembly, testing, maintenance, and repair.
