RS485 Connector for SEN0642

I see that the sensors do come with an adapter cable but if I want to install this far away from my Arduino I need the cabling to be weatherproof all the way down into my IP rated enclosure so I can't just solder a longer cable onto the adapter. I would like to find the exact connector that is used on the adapter and put that onto my own (longer) cable so it would be a nice and clean installation.
Or is it possible to open the sensor and just wire a longer cable directly through the cable gland on the sensor itself?
Do you have the exact sensor model or a clear photo of the connector? Weatherproof connectors can look similar while using different pin layouts, thread sizes and seals.
I would avoid opening the sensor, as replacing the internal cable may compromise its IP rating and warranty. The safer approach is to use the matching male/female connector or place the supplied adapter connection inside a small IP-rated junction box, then run a suitable outdoor cable to the main enclosure. Also check the interface type, if it uses I2C, a long cable may cause communication problems even when the wiring is weatherproof. You should check these connector types: https://www.pcbway.com/blog/Engineering_Technical/Which_PCB_Connectors_Are_Best_.html
ahsrab.rifat I’ve run into a similar issue when working with outdoor sensor installations. Finding the exact mating connector is often harder than expected, especially when the connection needs to remain weatherproof over a longer cable run. It may also be worth comparing different electrical plug connector types to find a compatible sealed option without modifying the sensor itself.
