M16 front lock panel PCB welding circular metal connector, designed for industrial equipment interconnection, uses a circular metal shell to ensure structural strength and protection performance, supports PCB panel welding installation, the panel is fixed on the outside, the connection nut is locked, and the connection is stable and vibration-resistant. It provides 3-24 pin core flexible configuration, adapts to multi-scenario signal/power transmission requirements, thread specifications are compatible with M16/M18, compact size (diameter 20mm), is a reliable connection solution in the fields of industrial automation, instrumentation, etc.
1. Product Features
The M16 front-lock panel PCB welding circular metal connector is built to industrial standards and has significant core advantages:
Structural design: The circular metal shell has excellent impact resistance and anti-electromagnetic interference performance, and the surface treatment enhances corrosion resistance and adapts to complex working conditions; the front lock panel design is matched with an outer fixed bracket, which is easy to install and saves space. The nut tightening locking mechanism ensures that the plug and the socket fit tightly to eliminate the risk of loosening and falling off.
Electrical performance: Supports high-density integration of 3-24 pins to meet the needs of multi-signal/power mixed transmission. The PCB welding interface ensures stable signal transmission, low contact resistance, strong antioxidant ability, and adapts to high-frequency plug-in and long-term use.
Compatibility and adaptability: Provide M16×0.75 and M18×0.75 double thread specifications to adapt to different installation environments; the compact body takes into account both strength and lightness, and is compatible with mainstream panel opening sizes.
2. Product size and number of pins
Dimension parameters:
Male head: body diameter 20mm, total length 16.5mm (including threaded section 15.0mm), inner side adapted to M16×0.75 threaded connection;
Female head: body diameter 20mm, total length 14.5mm (including threaded section 14.5mm), outer side adapted to M18×0.75 threaded fixation.
Both models adopt a stepped structure design, with pin/socket contacts at the front end and PCB soldering pins reserved at the back end for precise docking with the circuit board.
Number of pins range: Provide a full range of configurations from 3 pins to 24 pins, support customized pin layout, meet the diverse needs from simple signal transmission to complex system integration, and adapt to modular connection solutions for different scenarios.
This series of products has become the preferred connection solution in the fields of industrial control, intelligent equipment, rail transportation, etc. with its reliable mechanical performance and flexible electrical configuration.
