Why Choose CONNODER
Compact, High-Performance M5 Circular Connectors?

Small as they are, M5 connectors carry critical signal and power transmission tasks. With a 20+ R&D team and 10+ years of industry experience, CONNODER perfectly blends “miniaturization” with “high performance”.

01 Designed for Compact Spaces, Ultimate Miniaturization

M5 Thread Size +
With a diameter of just 5 mm, it is one of the smallest industrial circular connector standards available, perfectly suited for space-constrained applications such as micro sensors, encoders, and PLC I/O modules.
Versatile Mounting Options +
Multiple mounting options including PCB board mount and wire termination are available, flexibly adapting to different equipment structure requirements.
Straight and Angled Versions +
Straight connectors save axial space, while angled connectors optimize routing paths, reduce stress, and improve overall layout efficiency.

02 High Performance, Stability and Reliability

High Protection Rating (IP67/IP68) +
Precision sealing ring design effectively resists dust, water, and oil contamination, ensuring stable operation in harsh industrial environments such as humidity, dust, and washdown.
Premium Contact Materials +
Gold-plated copper alloy contacts ensure low contact resistance, high conductivity, and excellent oxidation resistance, safeguarding signal integrity and stability.
Rugged, Durable Construction +
Metal or high-strength engineering plastic housings, combined with the M5 threaded locking mechanism, provide reliable mechanical connections that effectively resist vibration and impact.
Outstanding Electrical Performance +
Rated voltage of 60 VAC/DC and rated current of 1 A (3/4-pin) meet the transmission needs of most sensor and control signals.
