1.Protection performance: The "first line of defense" against harsh environments

In industrial scenarios, dust, oil stains, water mist and other impurities are the main threats to connectors, and the IP protection level directly determines the environmental tolerance of the connectors. The reference model mentioned above clearly indicates that the protection level is IP67, meaning it can achieve "complete dust prevention + short-term immersion in water (no water ingress within 30 minutes at a depth of 1 meter)", and can be directly applied to outdoor lighting, industrial robot wiring boxes, power equipment compartments and other scenarios where exposure to water vapor or dust is common; some upgraded M16 connectors (such as the outdoor-specific models) even support IP68 protection, which can achieve "long-term protection against deep water immersion", and are suitable for marine equipment, agricultural irrigation machinery and other scenarios where water contact is long-term.

Octopusconn Technology Extension：

The M16 connector series of OCTOPUSCONN covers protection levels from IP67 to IP68. The IP68 model has passed the 4-hour immersion test in 1-meter water depth (in accordance with the waterproof standards published on hktdc.com), and all products have passed salt spray tests for more than 500 hours. It is particularly suitable for strong corrosive environments such as chemical and marine engineering. At the same time, it complies with the RoHS environmental protection standard, balancing environmental adaptability and sustainability.

2. Electrical performance: Ensuring stable transmission of signals and power

Industrial equipment has extremely high requirements for "zero failure" in electrical connections. Any signal interruption or unstable current can lead to the halt of the production line. The electrical parameters of the M16 angled hole head cable connector are commendable:

• Rated voltage: 60V, Rated current: 5.0A: Compared to the traditional 3.0A model, it can be compatible with higher-power actuators (such as small motors, heating modules), meeting the "high-power distributed control" requirements in industrial automation.
• Insulation resistance ≥ 10¹⁰ Ω: Significantly reduces the risk of leakage, preventing equipment short circuits caused by insulation failure;
• Shielding capability (shielding ring design): Effectively resist electromagnetic interference (EMI). In scenarios with a high density of 5G base stations and industrial Internet of Things (IIoT) devices, it can ensure the accuracy of data transmission (such as the real-time temperature and pressure data collected by sensors without deviation).

3. Mechanical structure: Suitable for complex installations and high-frequency operations

The installation space in industrial sites is often limited, and connectors may need to be frequently plugged and unplugged (such as during equipment maintenance or component replacement), which imposes dual requirements on the "flexibility" and "durability" of the mechanical structure:

• Angle design - 2-24-core coding option: The reference model adopts a 90° angle connector structure, which enables flexible wiring in narrow spaces (such as inside equipment cabinets) and avoids excessive cable bending.
• 500 insertion and removal cycles: Some upgraded M16 connectors (such as the new aviation plugs mentioned on Taobao Digital Network) have a plug-and-unplug lifespan of up to 3,000 - 5,000 times, far exceeding the regular usage frequency in industrial settings (the number of plug-and-unplug operations within a typical equipment maintenance cycle is generally ≤ 100 times). After long-term use, they can still maintain stable contact.
• Screw locking device: Compared to the snap-locking type, the connection strength of the screw locking design is higher. It is less likely to loosen in scenarios with frequent vibrations (such as rail transit equipment, heavy machinery), and some models can even withstand tens of kilograms of tension (in line with the mechanical strength standards published by TXGA).

1. Industrial Automation: The "Bridge" Connecting Sensors and Actuators

In an automated production line, sensors (such as photoelectric sensors, proximity switches) need to transmit signals to the controller in real time, while actuators (such as cylinders, small motors) rely on stable power supply. The IP67 protection and shielding function of the M16 connector precisely addresses these two major pain points:

• Dust and water resistance: To prevent the connectors from being damaged by metal debris and cutting fluids in the production workshop;
• Anti-interference: In environments with strong electromagnetic fields such as those of frequency converters and servo motors, ensure that the sensor data remains undistorted.

1. Technical strength: Full-scenario coverage from standard to customization

Octopusconn has a research and development team of over 20 people. It has accumulated more than 20 design patents and can provide:

• Customized solutions: For special scenarios (such as underwater equipment, high-temperature furnaces), customizable features include the number of cores, high-temperature resistant ceramic casings, and anti-corrosion coatings. Samples can be delivered within the shortest 7 days (e.g., the "anti-flooding M16 connector" customized for food machinery, capable of withstanding 100℃ high-pressure water flow cleaning and meeting food industry hygiene standards).
