20A M19 3+5 Pin Brass Gold-Plated Circular Connector 300V Multi Pin Plug Socket

1. 3+5 Split Pin Layout for Isolated Power & Signal Transmission

• This M19 multi-pin circular connector adopts a professional 3+5 functional split design with isolated power and signal circuits. 3 pins support 15A high-current power transmission, while 5 pins deliver precise multi-channel signal conduction, effectively eliminating current interference and ensuring pure signal output.
• With a rated voltage of 300V, the connector provides sufficient electrical safety margin. It realizes integrated power supply and multi-signal synchronous transmission in one connector, optimizing internal equipment wiring and simplifying circuit layout.
• Reasonable channel distribution and independent insulation avoid circuit crosstalk, signal disorder and data loss, supporting long-term continuous and stable operation of electrical equipment.

2. Premium Brass Gold-Plated Contact Pins

• The internal contacts are made of high-quality brass with precision gold-plated finish. Compared with ordinary tin-plated pins, it features higher conductivity and lower contact resistance, ensuring zero voltage drop under 20A high current and loss-free signal transmission.
• The gold-plated layer delivers excellent anti-oxidation, anti-corrosion and anti-sulfuration performance, resisting erosion from moisture, dust and weak acid-base environments. It effectively prevents contact failure caused by long-term oxidation.
• The wear-resistant gold-plated surface withstands hundreds of repeated plugging cycles, maintaining precise contact accuracy and stable electrical performance for an extended service life.

3. Standard Male & Female Plug and Socket Matching

• Equipped with complete male plug and female socket pairing structure in standard M19 circular size. Precise docking tolerance ensures tight fitting and strong compatibility with mainstream M19 wire harnesses and accessories for plug-and-play installation.
• Built-in anti-loosening limit structure maintains stable connection under equipment vibration and slight wire pulling, preventing loose docking, power failure and signal interruption during operation.
• Smooth plugging design with high fault tolerance adapts to mass production assembly, on-site debugging and daily equipment maintenance, greatly improving installation and replacement efficiency.

4. Heavy-Duty Industrial-Grade Durability

• The high-strength insulating housing features outstanding compression resistance, impact resistance and wear resistance, resisting daily collision and extrusion in industrial and outdoor environments without deformation or cracking.
• It meets 300V insulation standards with independent circuit isolation, effectively preventing electric leakage, short circuit and cross-circuit risks to ensure safe low-voltage electrical operation.
• Excellent temperature resistance and aging resistance enable stable mechanical and electrical performance under temperature alternation, humid and dusty working conditions for long-term all-weather service.

5. Wide Application Scope

• Widely used in industrial automation equipment, intelligent control systems, outdoor lighting facilities, small new energy supporting devices and security intelligent terminals for integrated power and signal connection.
• Ideal for industrial and outdoor electrical equipment requiring high-current power supply, multi-channel signal transmission, anti-oxidation and high connection stability.
