Product Overview

The Sinyinda SYCBCHY10P2D8XF is a 2+8 composite power and signal socket female connector designed for medium-to-high power drive-control collaborative scenarios. This product breaks through the conventional 25A current-carrying bottleneck, elevating the rated current of a single pin in the main circuit to 30A, while retaining 8 channels of 3A signal paths for collaborative functions such as status feedback, enable control, and temperature monitoring, perfectly filling the market gap of "pure power interfaces lacking control, and low-current composite interfaces with insufficient power." With a rated voltage of DC 500V, an operating temperature range of -20℃ to +100℃, copper-gold-plated (1u) contacts ensuring synchronized stable transmission of high current and weak signals, four corner M3 countersunk screw holes providing vibration-resistant secure mounting, and a recommended mating cycle life of 1000 insertions, it is particularly suited for scenarios with rigid demands for "30A current-carrying margin plus 8-channel control redundancy," such as servo drive integrated power-feedback ports, energy storage PCS power modules, AGV automatic charging stations, and industrial camera light-source linkage interfaces.

Core Differentiating Advantages

• 30A Current-Carrying Capacity Upgrade:Compared to same-size 25A models, the main circuit current-carrying capacity is increased by 20%, and temperature rise is reduced by 15℃, reserving ample safety margin for servo motor startup surges and peak operating conditions of energy storage modules, preventing terminal annealing failure caused by prolonged full-load operation.
• 2+8 Balanced Configuration Design:The 2 channels of 30A meet single-phase or dual-phase power transmission, while the 8 signal channels can be flexibly allocated for enable, fault feedback, temperature sampling, encoder A/B/Z phases, CAN communication, etc., achieving single-port integration of "power plus closed-loop control," replacing the traditional dual-interface solution of "power socket plus signal socket."
• Power-Signal Thermal Isolation Structure:A thermal insulation rib groove is added between the main circuit terminals and the signal area, keeping the temperature rise in the signal area below 10℃ during 30A full-load operation, preventing high temperatures from causing oxidation of signal terminal plating or creep of the PA substrate.
• High-conductivity low-loss contacts:Copper substrate + gold plating (1u) + nickel underlayer three-layer process, contact resistance ≤3mΩ, single-pin power consumption <2.7W at 30A full load, reducing heat generation by 25% compared to competitors.
• Vibration-resistant mounting verification:Four-corner M3 countersunk screw holes + housing reinforcing ribs, passing 10G random vibration testing (2h/axis), suitable for high-dynamic environments such as AGV mobile charging and vehicle-mounted energy storage.
• Long-life reliability:Contact resistance change rate <10% after 1000 mating cycles, maintaining stable conduction under 30A current, meeting the maintenance-free requirements for the entire equipment lifecycle.

Vertical application guide

⚙️ Servo drive power and feedback integrated port:

• 2 circuits of 30A transmit motor U/V phase power, and 8 signal circuits are allocated as: enable, fault feedback, temperature NTC, encoder A/B/Z phases, CAN_H/CAN_L, achieving single-cable interconnection between driver and motor, reducing wiring quantity by 50%.
• Selection tips: Encoder signals are recommended to use differential routing with shielded layers grounded at both ends; 30A power lines require ≥4mm² to match current-carrying capacity.
