Ultra-Compact Design

With a mere 4mm length, the KH-102540-DZ pogo pin connector is among the smallest pogo pin connectors available, tailored for devices where every millimeter counts, such as smartwatches, wireless earbuds, or micro-sensors. Its gross weight of 0.037 grams minimizes the overall device weight, a critical factor for portable electronics. This compact design provides engineers with greater flexibility, enabling integration into tightly packed circuits without sacrificing performance.

Material and Manufacturing Excellence

The KH-102540-DZ pogo pin connector features a brass alloy pin barrel and head, selected for its superior conductivity and durability. Brass alloy reduces contact resistance, ensuring efficient signal transmission, while its resilience withstands repeated mating cycles. The pin head’s surface is finely treated to minimize wear, enhancing long-term reliability. Packaged in bags, the product supports efficient bulk handling, reducing storage and transportation costs while protecting against environmental factors.

Electrical Performance and Longevity

This pogo pin supports a continuous current of 1.0A, suitable for low-power devices, and operates below 12V at 25°C, making it compatible with battery-powered or low-voltage systems. Its positive force exceeds 70gf, ensuring stable contact even under vibration or slight misalignment. With a lifespan surpassing 10,000 mating cycles, the KH-102540-DZ is built for durability, thanks to its optimized internal spring and high-quality materials, meeting the demands of high-frequency applications.

Pogo Pin Mechanism

As a pogo pin spring probe connector, the KH-102540-DZ leverages a spring-loaded design to ensure flexible contact. The spring compensates for minor alignment errors, enhancing reliability and simplifying assembly. In wearables, it serves as a charging or data transfer interface, while in IoT sensors or 5G micro-modules, it supports high-speed signal transmission with minimal interference, aligning with Kinghelm’s focus on system compatibility.

Diverse Applications

The KH-102540-DZ shines in ultra-compact applications. In wearables like fitness trackers, it enables reliable charging contacts. In micro-communication modules, such as IoT sensors or 5G base stations, it ensures stable signal paths. Its lightweight and durable design also suits emerging fields like drones or robotics, where it connects antennas or sensors efficiently.

Installation and Care

The KH-102540-DZ is typically surface-mounted or through-hole soldered onto PCBs, with its pin head designed for easy mating alignment. Maintenance involves occasional cleaning of contact points to remove oxidation, particularly in dusty settings. In humid environments, additional protective measures are recommended to preserve performance.

Industry Alignment

The rise of 5G and IoT has heightened the need for low-impedance, durable connectors. The KH-102540-DZ’s 4mm design and ROHS-compliant brass alloy align with these trends, supporting high-frequency signal demands and environmental standards. Its cost-effectiveness, driven by lightweight construction and bulk packaging, makes it attractive for manufacturers.
