Y0509

Board-to-Board Connectors | 0.5mm General-Purpose Board-to-Board (BTB) Connector

Core Advantages

• Versatile & Compact: 0.5mm standard pitch + 5.0mm stacking height, suitable for most board-to-board scenarios with PCB-space-friendly design.
• Electrically Reliable: 50V rated voltage, 200V withstanding voltage, delivering stable and safe electrical transmission.
• Excellent Contact: Gold-plated terminals provide oxidation resistance, stable contact, and long-term reliability without failure.
• Comprehensive Selection: 4–80 Pin full coverage, adaptable from low-current to medium-signal applications.
• Precision Tolerances: Tight dimensional tolerances, smooth mating, easy integration with standard PCB layouts.
• High Cost-Effectiveness: Locally mass-produced, significant cost advantage vs. imported alternatives.

Product Introduction

Y0509 Series is YQM's 0.5mm pitch, 5.0mm stacking height general-purpose board-to-board (BTB) connector. Utilizing LCP flame-retardant housing with phosphor bronze / brass gold-plated terminals, it covers a comprehensive 4–80 Pin specification range. Purpose-designed for stable mid-to-high density PCB-to-PCB interconnection, it meets diverse general-purpose connection requirements across consumer electronics, smart hardware, automotive low-voltage systems, and more.
