Product Overview

The Sinyinda SYCBCHY9P3D6XF is a 3+6 composite power and signal socket female connector specifically designed for industrial automation and precision equipment. This product features a high-strength PA engineering plastic body and precision terminal layout, combined with gold-plated copper (1u) contact technology, achieving high-density integration of 3 channels of 25A high-current main circuits + 6 channels of 3A low-current signal circuits; rated voltage DC 500V, operating temperature -20℃~+100℃, RoHS environmental certification, recommended insertion/withdrawal life up to 1000 cycles, equipped with M3 countersunk screw holes at four corners, perfectly suited for scenarios with extreme requirements for "compact space + multi-channel high-reliability interconnection" such as industrial robot body joint interfaces, integrated power and signal transmission inside automated production line equipment, medical device power modules, and test and measurement instruments.

Product Introduction

Core advantages:

• High-Density Integrated Design:3 circuits of 25A main loops and 6 circuits of 3A signal loops are physically isolated within a compact space, reducing wiring count and saving installation space.
• Dual-Channel Independent Transmission:Power and signal loops are separated in layout, effectively suppressing electromagnetic interference, ensuring synchronized and pure transmission of 6 signal channels.
• High current-carrying capacity:Main loop single-pin 25A, total carrying capacity 75A, meeting multi-phase power supply requirements for medium-power equipment.
• High-conductivity contacts:Copper base material + gold-plated (1u) process ensures low contact resistance and high signal integrity, maintaining stable conduction even after long-term insertion cycles.
• Stable mounting structure:Four-corner M3 countersunk screw hole design prevents loosening from vibration, enhancing mechanical reliability and impact resistance.
• Long-life design:1000 mating cycles lifespan, meeting the needs of frequent equipment maintenance and modular replacement.

Engineer's Selection Guide

Applicable scenarios:

• Industrial robot body joint interfaces (servo power + encoder/temperature signals)
• Integrated power and signal transmission inside automated production line equipment (PLC/driver interconnection)
• Medical device power module interfaces (e.g., internal power supply and communication in CT/MRI equipment)
• Test and measurement instrument backplane interfaces (multi-channel acquisition + power supply)
• Internal BMS and battery cell connections in new energy battery packs

Selection recommendations:

• Must be paired with the male connector SYCBCHY9P3D6XM to ensure precise terminal alignment and contact reliability.
• For main circuit terminals, it is recommended to use a hydraulic crimping tool to ensure contact stability under 25A current carrying.
• For signal circuit terminals, it is recommended to use a dedicated crimping tool to avoid loose connections that may cause signal loss or bit errors.
• During installation, pay attention to the M3 screw torque (recommended 0.5N·m); over-tightening may cause the housing to crack.
• During wiring, keep the main circuit and signal circuit traces separated, and add shielding layers when necessary to further suppress EMI.
• The 6 signal circuits can be assigned to different functions such as CAN, RS485, analog acquisition, digital I/O, etc., as required.
• For higher protection ratings (e.g., IP65), outdoor versions with sealing rings are available.
