Multi Pin Male Female Connector M19 3+2 Pin Wire To Wire Low Current Power Data Connector

Product Overview

Product Overview & Core Design: This is a PA66 M19 wire-to-board connector with a 3+2 pin structure, specifically designed for electrical power supply and signal transmission in industrial and electronic equipment. The 3+2 pin split design (3 power pins + 2 signal pins) effectively separates power and signal transmission, avoiding mutual interference and ensuring the stability and accuracy of both power supply and signal transmission. It is a versatile wire-to-board connection solution suitable for various low-voltage electrical scenarios.
High-Quality PA66 Material Advantage: The connector shell is made of high-performance PA66 engineering plastic, which has excellent comprehensive performance—flame-retardant (meets UL94-V0 standard), high mechanical strength, wear resistance, and impact resistance. It also has good electrical insulation, corrosion resistance, and UV resistance, not easy to age or deform even in long-term use, and can adapt to complex indoor and outdoor electrical environments.
3+2 Pin Functional Division: The 3 power pins are used for stable power transmission, supporting the power supply demand of electrical equipment; the 2 signal pins are dedicated to signal transmission, with strong anti-interference ability, ensuring the smooth transmission of control signals, data signals, and other weak signals. The pin layout is scientific and reasonable, with precise positioning and anti-misplug design, avoiding incorrect connection and damaging equipment.
Wire-To-Board Connection & Installation: Adopts professional wire-to-board connection mode, which can be firmly connected with the circuit board, realizing reliable connection between wires and the board. The installation is simple and convenient, supporting crimping and soldering termination methods, compatible with 0.5-2.5mm² wires, suitable for different wiring specifications and installation spaces. The M19 circular structure is compact, saving installation space and adapting to the layout of small electronic equipment.
Environmental Adaptability & Durability: It can work stably in the temperature range of -40℃ to +105℃, adapting to extreme temperature environments such as severe cold and high temperature. It has good dustproof and moisture-proof performance (IP67 protection level), effectively blocking dust, moisture, and other impurities from entering the connector, ensuring long-term reliable use. The mating durability is not less than 5000 cycles, and the service life is up to 6 years.
Application Scenarios: Widely used in various electrical and electronic fields, including industrial control equipment, household appliances, automotive electronic accessories, medical equipment, communication equipment, and LED driving equipment. It is especially suitable for equipment that requires separate power and signal transmission, providing a safe, reliable, and efficient wire-to-board connection solution.

Before purchase, I had doubts about waterproof performance in heavy rain. The seller explained everything patiently and even shared real use cases. After sales, they replied quickly when I had small questions. The connectors work really well in our monsoon season—excellent service and product.
