M5 Circular Connector

M5 Series Waterproof Circular Connectors-Compact Reliability for Industrial & Sensor Applications 

Meet the M5 series connector — the ultra-compact, rugged solution designed to redefine reliable connectivity in space-constrained environments. As the smallest and lightest in the M-series lineup, it delivers uncompromised performance for industrial automation, sensors, robotics, and miniature electronic systems worldwide.

Core Performance of M5 Connectors: Engineered for Stability & Durability Electrical Specifications 

IP67 Waterproof & Dustproof: Screw-lock fastening ensures a tight seal when mated, protecting against water immersion and dust ingress — ideal for harsh industrial floors, outdoor sensors, and agricultural machinery. 

Long-Lasting Construction: Gold-plated brass contacts resist corrosion and wear, supporting over 100 mating cycles (up to 10,000 cycles for premium models) and a wide operating temperature range of -20°C to +95°C (extended to -40°C to +105°C for high-grade variants).

Premium Materials: Housings made of PUR or PA plastic (metal options available) offer excellent impact and vibration resistance (up to 10G), while halogen-free cable sheaths comply with RoHS and REACH standards.

Versatile Configurations for Every Need 

Our M5 series covers all application scenarios with flexible options: 

Pin Counts: 2-pin to 4-pin standard configurations, with ultra-high density (UHD) upgrades available on request. 

Installation Types: Straight and 90° angled cable connectors (pre-molded or field-wireable), PCB mount receptacles (front/rear fastened), and panel mount solutions. 

Cable Customization: Choose PVC or PUR cables in lengths from 0.2m to 10m (custom lengths available), with wire gauges ranging from 0.14mm² (AWG 26) to 0.25mm² (AWG 24).

Why Choose Our M5 Connectors? 

Space-Saving Design: 5mm outer diameter reduces size by 30% compared to larger circular connectors, perfect for dense PCB layouts and tight mechanical spaces like robot joints or drones . 

Broad Application Fit: Seamlessly integrates with sensors, actuators, medical devices, 5G base stations, and smart home equipment — elevating performance in automation, transportation, and communication systems . 

Whether you need a standard off-the-shelf model or a custom-engineered solution, our M5 series delivers the compact power, rugged protection, and consistent performance your project demands.
