Hirose Electric FX31 FunctionMAX™ Floating High-Current Connectors

Introduction

The Hirose Electric FX31 FunctionMAX™ Floating High-Current Connectors are engineered for high-current, floating board-to-board applications, particularly in automotive systems. With their robust design and ability to handle significant electrical loads, these connectors are ideal for demanding environments.

Part Description

The FX31 connectors are designed to support up to 25A per pin at a voltage of 800V, making them suitable for high-power applications. They feature a 9.5mm pitch and a stacking height of 20mm. One of the standout features of the FX31 is its floating structure, which allows for a tolerance of ±0.5mm in the X/Y directions and ±1.5mm in the Z direction. This design compensates for misalignment and absorbs vibrations, reducing PCB stress by 0.05mm in the Z direction. Additionally, these connectors can withstand temperatures up to +125°C, ensuring long-term reliability even in harsh conditions.
