CH1a Series Prinetd Circuit Board Connectors

Features and Advantages

The core feature is the tonometer-style contact. This design offers significant advantages: the wiping action upon insertion cleans the contact surfaces, ensuring low and stable contact resistance, while the inherent springiness of the contact provides excellent normal force and reliable performance under vibration. The 2.5mm pitch is a proven standard that offers a good compromise between high density and sufficient electrical clearance for many signal and moderate-power applications. The hybrid contact arrangement (double lines for core contacts, single lines for others) is an intelligent layout feature. Its primary advantage is that it concentrates a high number of contacts in a central, mechanically supported zone while using a simpler, space-efficient single-row design for peripheral lines, optimizing both density and structural integrity of the connector housing.

Application

These connectors are mainly used for the printed circuit connection of electronic equipment, serving as a critical backbone for internal system architecture. Their reliable, high-density design makes them suitable for:

● Backplane/Daughterboard Connections: Linking multiple PCBs in telecommunications switches, industrial computers, and data storage arrays.

● Internal Module Interfacing: Connecting power supply modules, processor boards, and I/O cards within a single chassis in medical imaging, test equipment, and defense electronics.

● High-Pin-Count Cable-to-Board Interfaces: Providing a reliable transition from internal ribbon or flex cables to the main PCB in aerospace avionics and sophisticated industrial controllers.
