Key Selection Points

Selection Criteria & Matching Requirements

Installation Space : Match the 5mm diameter limitation of M5 connectors, confirm the installation depth and surrounding space.
Signal/Power Demand : Select pin count (3-4Pin) and rated current/voltage according to transmission requirements.
Environmental Protection : Choose IP67 for general industrial use, IP68 for outdoor, humid or submerged scenarios.
Installation Method : Select panel mount, PCB solder or cable direct connection based on equipment structure.
Product Compatibility : Verify with Octopusconn M5 series specification sheet for pin definition, mating size and performance parameters.

Technical Note: M5 connectors are suitable for low-power signal transmission in miniaturized equipment; avoid overloading current/voltage to prevent overheating. For high-vibration environments, select threaded locking models with anti-loosening design. Always refer to the official specification sheet for accurate parameter matching before selection.
