Description
I. Product Positioning: A Trusted Choice for Industrial-Grade Connectivity
**
As a standardized interconnection component in the global industrial automation field, the M-Series industrial circular connectors comply with the core IEC 61076 standards (including IEC 61076-2-101/010 revisions). With their compact structure, excellent protection performance, and stable transmission capabilities, they have become the backbone connectivity solution for IIoT, smart manufacturing, new energy, and other sectors. From micro-sensors to high-power equipment, and from indoor control cabinets to extreme outdoor environments, the M-Series provides “zero-interruption” connection guarantees for industrial systems through its full-scenario adaptability.
II. Full-Series Specifications: Precisely Matching Diverse Needs
(I) Classification by Size Specifications (Core Model Parameters)
| Model | Thread Specification | Contact Range | Rated Parameters | Core Application Scenarios |
| M5 | M5×0.5 | 3-5 contacts | Voltage ≤60V DC, Current ≤2A | Micro pressure/temperature-humidity sensors, small actuators |
| M8 | M8×1.0 | 3-8 contacts | Withstand voltage 50V AC, Vibration resistance 50m/s² | Industrial valves, short-distance sensor interconnection |
| M12 | M12×1.0 | 3-19 contacts | 4A@250V (Standard type) / 10Gbps | Industrial Ethernet, PLC control, robots |
| M16 | M16×1.5 | 6-24 contacts | Current ≤16A, IP69K protection | Motor control, industrial power distribution |
| M23 | M23×1.0 | 12-32 contacts | Withstand voltage 1000V DC, 150A carrying capacity | New energy charging piles, high-power industrial equipment |
Note: M12 is the mainstream model in the market (accounting for over 60%). The X-coded version is specifically designed for Gigabit Ethernet transmission and serves as the core connectivity component for industrial networks.
(II) Classification by Functional Coding (Anti-misplug + Protocol Adaptation)
- Power Transmission Type: A-coding (4/5 contacts, 24V DC, ≤4A), C-coding (4 contacts, 110/230V AC, oil-resistant)
- Signal Transmission Type: B-coding (5 contacts, Profibus bus, impedance 100Ω±10%), D-coding (4 contacts, Profinet, shielding effectiveness ≥60dB), X-coding (8 contacts, Gigabit Ethernet, 10Gbps speed)
- Hybrid Type: Integrates power + signal pins (e.g., 12 contacts including 4 power + 8 signal), reducing the number of device interfaces
(III) Connection and Protection Options
| Type | Locking Mechanism | Protection Level | Core Advantages |
| Threaded Connection | Rotational locking (≥1/4 turn) | IP67/IP68 | Vibration resistance ＞50m/s², 1m underwater immersion for 48 hours |
| Bayonet Quick-Connect | 1/4-turn quick locking | IP67 | Plug-in life ≥5,000 cycles, efficient installation |
| Push-Pull Type | Axial press locking | IP68 | Blind mating success rate ＞99%, easy operation |
| Military-Grade Explosion-Proof Type | Explosion-proof housing + flame-retardant material | IP69K | Salt spray resistance ＞500 hours, UL94 V-0 flame retardant |
III. Core Technical Advantages: Addressing Extreme Industrial Challenges
- Full-Environment Adaptability: Operating temperature ranges from -65℃ to 200℃ (military grade), supporting IP67-IP69K protection to resist dust, liquids, oil, acid-alkali corrosion, and salt spray.
- Stable Transmission Guarantee: 360° metal braided shielding + ferrite bead, EMI suppression ≥30dB; copper gold-plated/silver-plated terminals with low contact resistance, 30% longer plug-in life, and failure rate only 1/5 of traditional RJ45.
- Efficient Installation Design: Offers two cable solutions—overmolded and field-installable. Some models support tool-free push-in wiring, reducing assembly time by 30%.
- Global Compatibility Standards: Fully compatible with mainstream industrial bus protocols such as Profinet, Profibus, and EtherNet/IP. Same-coding interfaces are backward compatible, reducing replacement costs.
IV. Typical Application Scenarios
- Industrial Automation & Smart Manufacturing: Interconnection of production line sensors, PLC controllers, industrial robots, and visual inspection equipment
- New Energy Field: Electric vehicle charging piles, photovoltaic inverter stations, and energy storage system power transmission
- Rail Transit & Vehicle-Mounted: Vehicle-mounted Ethernet, rail transit signal control, and AGV mobile device connectivity
- Communications & Data Centers: 5G base station equipment, server clusters, and industrial IoT gateways
- Special Environments: Chemical mines (explosion-proof type), medical diagnostic equipment (high-cleanliness type), and outdoor smart devices (weather-resistant type)
V. Selection Guide: Precisely Matching Requirements
- Select model by installation space: M5/M8 for micro devices, M12 for standard industrial equipment, and M16/M23 for high-power equipment;
- Match coding by transmission type: A/C coding for power transmission, D/X coding for Industrial Ethernet, and B coding for Profibus bus;
- Choose protection level by environment: IP68/IP69K for outdoor/humid environments, and threaded connection type for vibration scenarios;
- Select connection method by installation efficiency: Quick-connect type for mass assembly, and field-installable type for complex wiring.
