PHCONNECTOR Launches Micro Connector for Highdensity Pcbs

As electronic devices continue to shrink in size while increasing in complexity, engineers face significant challenges in achieving high-density, reliable connections between internal cables and printed circuit boards (PCBs). Traditional connector solutions often prove too bulky for compact devices. This article examines the PHCONNECTOR series of miniature connectors, analyzing their unique advantages in addressing high-density connection challenges.

Market Demand and Technical Background

The rapid development of consumer electronics—including smartphones, tablets, and wearable devices—along with growing demand for compact, high-performance components in industrial control and medical equipment has driven increased component density on PCBs. Conventional connectors occupy valuable board space, limiting device miniaturization. This creates urgent market demand for compact, reliable, and cost-effective connector solutions.

The PHCONNECTOR series meets these requirements with its 2.0mm pitch, post-installation height of just 8.0mm, and width of 4.5mm. Designed for high-density cable connections in confined spaces without compromising reliability, these connectors serve diverse applications:

• Consumer electronics: Smartphones, tablets, wearables, digital cameras
• Industrial control: PLCs, HMIs, sensors
• Medical devices: Monitors, diagnostic equipment, portable medical devices
• Automotive electronics: Infotainment systems, navigation, sensors

Key Features of PHCONNECTOR Series

Miniaturized Design

The 2.0mm terminal spacing optimizes space efficiency while maintaining electrical performance. With an installed height of 8.0mm and width of 4.5mm, these connectors enable ultra-thin device designs and higher PCB integration.
