DGZZI 5Pairs GX16 4Pin Male Female Circular Aviation Connector Plug 16MM Wire Panel Metal Connector

Easy to solder leads and passes a clean signal for each lead. Had difficulty taking apart one. Needed pliers to unjam it, but it works ok after reassembly.

Good quality decent price

16mm is the approximate diameter of the mounting hole into which the threaded end of the connector is mounted and secured (with supplied hex nut), which can be a point of confusion if you measure any other part of the connector's body. This connector worked perfectly for my application. Be sure to have a fine-tip soldering iron as, by necessity, the terminals are very small and closely spaced.

I bought these connectors to connect a friend's rotary attachment to a laser cutter of a current band. The fit of these 4pin aviation connector is fantastic . It matched the connector in the omtech laser cutter perfectly. It was quite easy to solder the necessary wires to the pond in the connector. Having both pieces of hardware is great if you are designing new hardware that needs a quick disconnect for for wires. The connector is keyed so you cannot connect them wrong.

Couldn't be happier. Great value. Perfect fit. Quality seems to be excellent. Each pin is clearly labeled on the plastic insulator.

The items are as described. One major plus was soldering the wires to the connectors. The solder stuck with ease and I did not have to rough up the posts to get it to stick.

The fit for the four pin is super tight and better then any factory one. A ham radio, cb radio a export here they are. So 5 perfect male and 5 perfect female connectors. Everything is in the box nothing missing. My equalizers will be perfect with thease connectors for mic input and output into my export radios. I'm a perfectionist so I can't stand junk. So when I say perfect they are. Thank you if I owned a radio repair shop I buy them all.

Used these to replace the old ones on our CNC. Worked perfect.
