Product Overview
The M5 Series Waterproof Circular Connector is an ultra-compact, rugged connection solution designed for reliable performance in space-constrained environments. As the smallest and lightest model in the M-series lineup, it supports stable power and signal transmission for industrial automation, sensors, robotics, and miniature electronic systems.
With screw-lock fastening, IP67 waterproof protection, gold-plated brass contacts, and flexible cable options, the M5 series is suitable for applications where compact size, vibration resistance, and consistent signal integrity are required.
01 / M5 CONNECTOR
Compact Circular Connector
Designed for sensors, actuators, miniature devices, and tight mechanical spaces.
02 / SCREW LOCKING
Tight mating connection for harsh environments.
Compact size.
Reliable industrial protection.
The M5 series helps reduce space while maintaining waterproof, dustproof, and vibration-resistant performance.
Why Choose M5 Connectors
The M5 series is built for equipment where installation space is limited but connection reliability still matters. Its 5 mm outer diameter helps reduce connector size compared with larger circular connectors, making it suitable for dense PCB layouts, robot joints, sensors, compact modules, and miniature electronic systems.
