M19 3+9 Pin Wire To Board Connector Waterproof Male Female Quick Lock Connector Company

This M19 3+9Pin wire-to-board waterproof connector is an industrial-grade component designed for secure interconnection between wires and PCB boards. It features a combined pin layout with 3 power pins and 9 signal pins, available in male/female configurations. Equipped with a thread-free Quick Lock self-locking mechanism, it enables tool-free plugging and reliable anti-loosening performance. As a factory-direct product, it adopts gold-plated brass contacts and high-strength insulation housing, supporting a wide temperature range from -40℃ to +105℃ and IP67 dust/water resistance. Ideal for both harsh outdoor environments and internal board-level connections, it serves as a preferred interconnection solution for industrial control, outdoor LED, and smart devices.

Key Points

3+9Pin Separated Power & Signal for Stable Board-Level Connection
3 dedicated pins for main power supply (suitable for low-to-medium power applications) and 9 pins for multi-channel signal transmission (supporting simultaneous sensor, control, and data signals). Physically isolated power and signal circuits eliminate crosstalk, meeting PCB board-level multi-interface integration needs and simplifying internal wiring.

Professional Wire-to-Board Design for Board-Mount Applications
One end for wire crimping, the other for direct PCB plug-in or soldering. Male/female pairs adapt to board-mounted sockets and cable plugs. The compact structure saves space, supporting both panel mounting and direct board installation for modular assembly and easy maintenance.

Gold-Plated Brass Contacts for Durable Conductivity in Wide Temperatures
High-purity brass with precision gold plating ensures low contact resistance and excellent oxidation resistance. It maintains stable electrical conductivity from -40℃ to +105℃, resisting loosening and signal degradation even after frequent plugging and long-term power-on operation.

Quick Lock Self-Locking for Tool-Free Fast Mating
Spring-loaded buckle design enables automatic locking upon insertion and easy release by pressing—no threads or tools required for efficient on-site assembly. The tight locking resists vibration and cable tension, preventing loose connections and power interruptions at the board level.

IP67 Dust & Water Resistance for Outdoor/Industrial Use
High-elastic sealing gaskets ensure a tight, gapless seal after locking, blocking rain, dew, dust, and light oil. Suitable for open-air installations, humid workshops, and dusty industrial environments.

Standard M19 Size with Factory Direct Supply & Customization
Standard M19 circular housing fits common wire gauges and board cutouts, with complete male/female pairs. As a manufacturer, we offer mass production, ODM customization, and stable delivery.
