Selection of Octopusconn M16 Connectors: 3 Key Principles
1. On-demand matching principle: Reject "excessive core count" and "insufficient functionality"
- First, clarify the transmission requirements: distinguish between "pure power supply", "power supply + signal", and "pure signal" transmission types, and list the mandatory functional items.
- Reserve additional expansion space: For regular scenarios, reserve 1-2 spare cores; for special equipment (with a service life of ≥ 5 years), reserve 2-3 cores. This is to avoid having to replace the connectors again during later upgrades.
- Reference case: An automated production line uses the Octopusconn 6-core M16 connector, which not only meets the current requirements of "power supply + 3 sensor signals", but also reserves 1 spare core. When the counting function is added in the future, it can be directly enabled without the need to modify the hardware.
2. Scene adaptation principle: The environment and installation conditions determine the selection direction.
- Environmental protection requirements: For outdoor/damp environments, the Octopusconn models with IP67/IP68 water resistance rating should be preferred. For salt spray environments, the stainless steel shell version should be selected.
- Installation space limitation: The curved installation model is suitable for narrow spaces, while the straight model is chosen for regular scenarios. For panel installation scenarios, a dedicated fixing nut should be used.
- Operating temperature range: For extreme high and low temperature environments (-40℃ or above or +85℃ or below), the Octopusconn wide temperature customized model can be selected to ensure stable operation.
3. Quality-first principle: Choose professional brands and certified qualifications
- Core parameter verification: Focus on key parameters such as protection level, insertion and removal lifespan, and temperature range, and avoid low-priced inferior products.
- Comprehensive certification: Choose products that have passed CE, ROHS2.0, and ISO9001 certifications. All Octopusconn M16 connectors in the series comply with international standards and their quality is traceable.
- Brand service guarantee: Preferentially choose brands with a complete after-sales system. Octopusconn offers 24-hour technical consultation, sample testing, installation guidance and other full-process services. Its global customer base covers five continents, and the delivery cycle is stable.
M16 Chip Count Selection Guide: Uncovering 4 Common Pitfalls and Solving Them
1
Misconception 1: The more cores, the better.
Risks: Increased costs, complex installation, higher probability of signal interference
Solution: Determine the number of cores based on "current requirements + necessary reserve". For example, when connecting a common sensor, 4 cores can be used, and there is no need to blindly choose 8 cores.
Octopusconn Solution: Offer free consultation services for equipment selection. Based on the equipment parameters and scene requirements, provide precise recommendations for the appropriate number of chips.

Misconception 2: Ignoring the matching of encoding types
Risk: Incorrect insertion of connectors of different codes (A/B/D, etc.) may cause damage to the equipment.
Solution: Uniformly select the same encoding model. The Octopusconn M16 connector defaults to using the industry-standard A-Coding. For special requirements, other encodings can be customized.
Notes: When making the selection, clearly inform the coding requirements to avoid procurement errors caused by mismatched codes.
3
Myth 3: Ignoring the compatibility between cables and core numbers
Risk: The cable's wire diameter does not match the number of cores, resulting in poor contact or inadequate heat dissipation.
Solution: Octopusconn provides matching cable components. The corresponding wire diameter is selected based on the number of cores (the range of outgoing wires is 4-6mm). For high-core-count models, multi-strand twisted wires are used to reduce signal interference.
Selection Tip: When purchasing connectors, it is recommended to pair them with original factory cables to ensure system compatibility.
4
Myth Four: Products with lower prices have higher value for money.
Risks: Poor material quality, ineffective protection, short lifespan, and high maintenance costs in the later stage.
Analysis: By comparing the core parameters with the brand's strength, Octopusconn uses high-purity copper alloy contacts and high-quality sealing components. Although the initial purchase cost is slightly higher, its average lifespan reaches 5-8 years, which is much higher than the industry average. Therefore, its long-term cost-effectiveness is even better.
