Product Overview

The SYCBCHY9P3D6XM from SYC is a 3+6 composite power and signal plug male connector specifically designed for industrial automation and precision equipment. This product features a high-strength PA engineering plastic housing and precision terminal layout, combined with copper gold-plated (1u) contact technology, achieving high-density integration of 3 circuits of 25A high-current main loops + 6 circuits of 3A low-current signal loops; rated voltage DC 500V, operating temperature -20℃~+100℃, RoHS environmental certification, recommended insertion life up to 1000 cycles, equipped with M3 countersunk screw holes at four corners, precisely mating with the female connector SYCBCHY9P3D6XF to form a complete interconnection system, perfectly suited for scenarios with extreme requirements for "compact space + multi-channel high-reliability interconnection + frequent insertion/withdrawal" such as industrial robot joint cable harness fabrication, integrated power and signal cables inside automated production line equipment, output ends of medical equipment power modules, and probe cables for 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 joint cable harness production (servo power + encoder/temperature signals)
• Integrated power and signal cables inside automated production line equipment (PLC/drive interconnection)
• Output interface for medical device power modules (e.g., internal power supply and communication in CT/MRI equipment)
• Probe cable interface for test and measurement instruments (multi-channel acquisition + power supply)
• Internal BMS and battery cell connection harness for new energy battery packs

Selection recommendations:

• Must be paired with the receptacle SYCBCHY9P3D6XF 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.
• It is recommended to add a strain relief structure at the cable end to prevent terminal loosening caused by frequent bending.
