In multiple high-end fields such as industrial automation, rail transit, robotics, and new energy, the selection of connectors is directly related to the stability and reliability of the system. With the development trend of equipment miniaturization and functional integration, traditional connectors have gradually exposed many limitations. The M16 circular connectors, as a leader in the medium-sized connector market, is rapidly replacing traditional connectors and demonstrating strong capabilities in harsh environments.
This article will comprehensively compare the M16 circular connector with traditional connectors from multiple dimensions such as structural performance, electrical characteristics, and environmental adaptability, helping you better understand its value in industrial applications.
1. Comparison of Structural Design
| Project | M16 circular connector | Traditional connectors (such as rectangular terminals, universal terminal blocks) |
| Size and Layout | Compact circular structure, space-saving, supports high-density wiring | It is usually large in volume and occupies a considerable amount of installation area |
| Size and Layout | Threaded locking/push-pull quick lock, stable connection | Most of them are snap-fit or plug-and-pull types and are prone to loosening |
| Core number configuration | 2 to 8 cores or more, supporting power + signal mixing | The core number is limited and the structure is separated |
Advantage Analysis: The M16 connector features a standard circular housing and is compatible with various termination methods (soldering, crimping, and solder plate), making it more suitable for applications with limited space and high installation accuracy requirements.
2. Electrical performance comparison
Project | M16 circular connector | Traditional connectors (such as rectangular terminals, universal terminal blocks) |
| Rated voltage | It can reach 250V | It generally does not exceed 150V |
| Rated current | Usually 5A, and some models support higher currents | Mostly 1 to 3A |
| Contact resistance | As low as 5mΩ, with high transmission efficiency | High contact resistance is prone to heat loss |
Shielding design | It supports a shielded housing and has strong anti-electromagnetic interference ability | Most have no shielding function and weak anti-interference ability |
Advantage Analysis: In systems that require stable high current transmission, low power consumption, and high anti-interference capabilities, the M16 connector offers more reliable performance and can effectively enhance the efficiency and security of the entire system.
3. Comparison of environmental adaptability
Project | M16 circular connector | Traditional connectors |
| Protection grade | It can reach IP67/IP68, being waterproof and dustproof | Most of them are below IP20 and cannot be used outdoors |
| Working temperature | -40℃ to +85℃ or higher | It is mostly between -10℃ and +60℃ |
| Corrosion resistance | The metal nickel-plated shell and sealing ring design are oil-proof and resistant to chemical corrosion | Exposed terminals are prone to oxidation or corrosion |
Advantage Analysis: For outdoor equipment, heavy industrial sites, shipping or new energy systems, M16 connectors have stronger weather resistance and environmental protection capabilities, far exceeding traditional products.
4. Comparison of Application Flexibility
Project | M16 circular connector | Traditional connectors |
| Wiring method | Multiple methods such as crimping, welding, and screw pressing | Most are fixed by crimping terminals or screws |
| Installation mode | Flexible methods such as panel installation, post-panel installation, and on-site assembly | Usually, only one or two fixation methods are supported |
| Quick-installation feature | Optional push-pull self-locking structure, supporting quick plugging and unplugging | Installation is more cumbersome and requires tools |
Advantage Analysis: In sites where rapid maintenance and replacement of connectors are required, the M16 connector, with its standardized interface and modular structure, can significantly enhance construction efficiency.
Summary：Why are more and more enterprises turning to M16 circular connectors?
Enhance the reliability and stability of the system
