M8 connector-panel rear lock welding wire connection plug, adopts screw locking structure and brass nickel-plated material, has double nut panel internal and external fixing design, and the pin core tail supports welding wire connection. The product combines stability, corrosion resistance and installation flexibility, and is suitable for signal transmission and power connection in industrial equipment, instrumentation and other scenarios, providing an efficient solution for cable and equipment integration.
1. Product Features
The connector uses a nickel-plated brass body to ensure conductivity and corrosion resistance. The screw locking and double nut structure can achieve dual fixation inside and outside the panel, adapt to different installation environments, and effectively resist vibration and loosening risks. The pin core tail adopts a welding wire process, which is convenient for quick welding and fixing of cables and improves connection reliability. The overall design takes into account both mechanical strength and electrical performance, supports high-frequency plugging and unplugging in multiple scenarios, and meets the stringent requirements of industrial grade.
2. Product size and number of pins
The product provides two specifications and sizes:
Standard type: diameter 22.0mm, length 20.0mm, thread specification M8×1.0 (main body)/M8×0.5 (locking), suitable for 3-pin cable connection;
Compact type: diameter 16.1mm, length 19.6±0.15mm, thread specification M8×1.0, also supports 3-8 pin configuration.
Both models adopt rear-lock welding wire structure, with 3-8 pins, which can meet the connection requirements under different space layouts and take into account compactness and practicality.
