content: Could anyone let me know what connector is the round one? I need to connect my device directly to a scale without the need for a pair of standard 9 pin serial connector. Many thanks!https://www.coleparmer.co.uk/i/adam-equipment-rs-232-cable-for-scale-indicator/1171033

content: Thank you @tooki, @jonpaul!The serial cable connects using the round connector to a serial port on the Adam AE 403 indicator:https://www.adamequipment.co.uk/ae-403The serial port is on the bottom (from page 7 in the user manual:https://www.adamequipment.co.uk/media/docs/Print%20Publications/Manuals/AE403_UM_EN.pdf:Seeing the metal shield around the female connector I am thinking that it is a "very special" connectorWill not have access to the scale/indicator for about 2 week so unfortunately I cannot provide dimension. I am sorry for this; I learned this lesson and will know next time.Not sure if it helps, on the indicator details page above there is also a service manual:https://www.adamequipment.co.uk/media/docs/Print%20Publications/Manuals/AE403_SM_EN.pdfI read both manuals but the connector codes are internally assigned, could not find anything based on those.

content: I am not 100% sure but I think it's the 4 pin Eurofast M12 femaie connector.

content: Nah, its not M12.Note the metal surround with the alignment notch and female sockets. Also, the straight knurling on the lock nut.I think the same connector type is used for the 7-pin strain gauge connection, seen here.https://youtu.be/286rBnw3-Bw?t=47Couldn't see a matching Amphenol or Hirose, which were my first guess.

content: @voltsandjolts you are perfectly right, it is the same connector: load cell connector has 7 contacts, serial port connector has 4 contacts.

content: You sure they're not GX Aviation connectors ? DIN connectors are not quite the same.

content: @Jwillis, I am not sure. I looked for GX Aviation connectors on Google Images Search and could not find yet such a connector that has a metallic shield.

GX12, GX16 or GX20Oh wait I see what you mean about shielding . But I wonder if that is necessary .

content: Thank you @Jwillis! I noticed that the connectors on Amazon do not have this metallic shield (please see the attachment to this post).Edit: I am not sure if the shield is necessary. Regarding the size, I will get a caliper with me next time will be on the site.

content: Quote from: doru.cazan on April 01, 2023, 05:32:00 pmWhat about these. They,re not a GX aviation but a XS aviation.https://www.amazon.ca/Aviation-Push-Pull-Circular-Socket-Connector/dp/B07QF3MSWWMaybe that will narrow things down a bit more.

content: @Jwillis, these XS connectors look very similar, have to find one with thread instead or screw / thread. Thank you
