What Are M8 Connectors?
M8 connectors are small circular connectors designed for electrical and industrial applications that require a reliable, secure, and efficient connection in tight spaces. Their compact size and ability to withstand harsh conditions make them an essential solution in modern industrial automation.
They are widely used for connecting sensors, actuators, valves, control systems, and industrial communication networks. Their robust construction makes them perfect for mobile applications, robotics, automated transport systems, and environments exposed to vibration or moisture.
Technical Features of M8 Connectors
Electrónica Embajadores’ M8 connectors combine compact design, high mechanical resistance, and easy integration. Key features include:
- Small size: Designed to fit applications with limited space.
- High resistance to shocks and vibrations: Made from materials such as PVC, PUR, or TPU with robust metal or plastic housings.
- Dust and water resistance: Several models offer IP67 or IP68 protection, suitable for outdoor or wet environments.
- Variety of pins: Available in 3, 4, 5, 6, and 8-pin versions for different signal and power types.
- International compatibility: Compliant with IEC 61076-2-104 standards, ensuring universal use.
- Connection options: Panel mount, pre-cabled, solder, screw, or IDC connections.
Common Applications of M8 Connectors
Thanks to their reliability and compact format, M8 connectors are used across numerous industrial sectors. Typical applications include:
- Industrial sensors and actuators: For connecting detection and control devices on production lines.
- Factory automation: Communication and power interfaces between control modules, PLCs, and machinery.
- Robotics and mobile systems: Integration into robotic arms, AGVs, drones, and moving machinery.
- Medical instrumentation and laboratory equipment: Used in devices requiring precision and reliability in sterile environments.
- Consumer electronics and smart home: For discreet yet effective connections.
M8 connectors are also suited for railway, food processing, and packaging industries, where hygiene and robustness are critical.
Coding and Formats of M8 Connectors
M8 connectors come with different codings to ensure correct mating and prevent assembly errors. The main codings include:
- A-Coded: The most common, used for sensors, actuators, and digital or analogue signals (3 to 8 pins).
- B-Coded: Designed for fieldbus systems such as Profibus.
- D-Coded: For industrial Ethernet (up to 100 Mbps, 4 pins).
- X-Coded: For high-speed applications (up to 10 Gbps, 8 pins).
Physically, M8 connectors are available as:
- Straight and angled connectors: Suitable for different space constraints.
- Panel mount: Male or female connectors for direct chassis or enclosure mounting.
- Pre-cabled: With cables of various lengths, in PUR, PVC, or halogen-free options.
- Screw, IDC or solder connections: Depending on installation requirements.
