Product Overview

The Sinyinda SYCBCHY90A16P4D12XF is a 4+12 composite power and signal socket female designed for high-power transmission and synchronous interaction of multiple control signals. This product features a high-strength PA engineering plastic body, combined with copper gold-plated (1u) contact technology, achieving 4 channels of 90A high-current main circuits + 12 channels of 4A low-current signal circuits as independent channels within a compact space of only 50.0mm×30.0mm; rated voltage DC 500V, operating temperature -20°C~+100°C, RoHS environmental certification, recommended insertion cycles lifespan up to 1000 times, equipped with M3 countersunk screw holes at four corners, perfectly suited for scenarios with extreme requirements for "power + signal integration" such as drone power battery interfaces, electric tool battery pack management systems, energy storage device BMS communication ports, and industrial AGV charging docking.

Product Introduction

Core advantages:

• Dual-channel isolation design:The 4-channel 90A main circuits and 12-channel 4A signal circuits are physically isolated, avoiding electromagnetic interference and ensuring signal purity.
• Ultra-High Current Carrying Capacity:Single pin of main circuit 90A, total carrying capacity up to 360A, meeting the needs of high-power equipment.
• High-conductivity contacts:Copper substrate + gold-plated (1u) process ensures low contact resistance and high signal integrity.
• Stable mounting structure:Four-corner M3 countersunk screw hole design prevents loosening from vibration and enhances mechanical reliability.
• Long-life design:1000 mating cycles lifespan, meeting high-frequency maintenance requirements.

Engineer's Selection Guide

Applicable scenarios:

• Integrated interface for drone power battery and flight control signals (e.g., DJI Matrice series modifications)
• Electric tool battery pack intelligent management system (BMS communication + motor drive)
• Energy storage device BMS communication port and PCS power conversion interface
• Industrial AGV automatic charging docking station (power + status feedback)
• Robot joint module power supply and encoder signal integration

Selection recommendations:

• If a higher temperature rating is required, LCP or PPS material versions are available (custom order required).
• If waterproofing is needed, an IP67 silicone sealing ring can be added (not standard).
• M3 screws should be made of stainless steel to avoid corrosion affecting disassembly.
• Paired with male connector HY90A 4+12 to ensure insertion force and contact reliability.
• During wiring, keep the main circuit and signal circuit routed separately to avoid crosstalk.
