FLASH HOBBY 5 Pairs MT30 Connector 2mm 3-Pin Male and Female Motor Connector Plug Set for RC Model

These are very useful connectors for industrial applications. They're easy to solder on and have perfect retaining force. I like that + and - are molded into the plastic, so you don't have to worry about different people choosing different pinouts. I use the earth gnd pin as a signal line.Every engineer should have some of these on hand.

I am very happy with the product - they are smaller than I was expecting, but that is on me. I like the connectors and I like the back shells that cover the solder joints and limit the stress on the wires - something I would have to had built myself if they weren't already designed in. It looks like the biggest wire I can use with them is probably 16 gauge (depending on the thickness of the insulation) which is fine for a lot of applications I have.

Great for connecting 3-lead motors.

Figure out the connections once, then they can't be wrong when you reconnect later. Small and light as well.

I really liked these. I wasn’t planning on using the extra solder joint cover plastic piece to save weight, but it was so light, clean, and convenient compared to shrink wrap that it ultimately was the best choice.

I do like this product its easy to put together but it's hard to solder the connections together

Good set of MT-30's, Great for setting up ESCs or anything that requies 3 wires.

They're pretty decent. Plastic doesn't stand up to heat too well, but just be careful when you're soldering and you should be fine.
