Overview

In-depth Product Details & Applications

Solution Overview

High-quality pin headers/female headers are the most fundamental and critical connecting components in industrial control equipment. This solution adopts square-pin gold-plated pin headers, paired with high-elasticity phosphor bronze female headers, to provide a stable and reliable signal transmission channel for PLC control boards. The products have undergone rigorous industrial-grade reliability testing and meet the requirements of harsh industrial environments.

Main Application Areas

PLC controllers: Connection between CPU mainboard and I/O expansion boards, power module interfaces, communication module interfaces
DCS systems: Control station card connections, fieldbus interfaces, operator station communications
Industrial robots: Internal board connections in control cabinets, teach pendant interfaces, servo drive control boards
CNC machining: CNC system mainboard connections, spindle drive interfaces, encoder feedback signals
Motion controllers: Multi-axis control card interconnection, pulse/direction signal transmission, encoder interfaces

Solution Advantages

The square-pin four-sided pyramidal tip reduces insertion force; the gold plating thickness is 0.76μm or more, withstanding more than 500 mating cycles; the insulator uses UL94V-0 flame-retardant LCP material, resistant to high temperatures up to 260℃. Produced and inspected strictly in accordance with the IEC 60603-13 standard.
