What the AI looks for in Cylindrical Connectors

Series and shell size match: Buy plug and receptacle from the same series and shell size, for example GX16 to GX16, or MIL-DTL-5015 shell to the same shell and insert arrangement. The thread pitch, shell diameter and insert must all line up.
Pin count and insert arrangement: The pin count and keying must match exactly on both halves. Same-shell connectors with different pin counts will not mate.
Power rating per contact: Size contacts by per-contact current with margin, and confirm the voltage rating covers mains if you use mains. Generic hobby connectors are often marketed for loads beyond what their small contacts handle safely.
Panel mounting: Confirm the receptacle style (rear-mount, front-mount, or square flange) and the panel cutout diameter before drilling. The wrong mount style or cutout means the receptacle will not seal or will not fit.
Sealing and backshell: For wet environments, choose versions with sealed inserts, a gasketed receptacle, and a cable gland matched to your cable outer diameter. Unsealed hobby versions let water reach the contacts.

Amphenol: MIL-DTL-5015 and MIL-DTL-38999 style connectors for heavy-duty use.
TE Connectivity: Industrial and military cylindrical connector families.
Weipu: Threaded SP-style industrial connectors with stated IP ratings.
Bulgin: Sealed equipment connectors for outdoor and harsh environments.
Switchcraft: Panel-mount circular connectors common in audio and instrumentation.

Generic GX12/GX16 aviation connectors for mains voltage or high-current loads.
Solder-cup connectors on cables that will flex or vibrate unless the backshell clamps the cable firmly.
Ordering without measuring the panel cutout and the cable outer diameter.

It refers to the nominal shell diameter in millimetres; the pin count must still be matched separately.
