connectorpins
I was looking at this component, which has strange interface pins.
I have never seen anything like it. I wonder how am I supposed to connect to them. What connectors can I use and what's special about them? Is it good for RF stuff for example? What are they called? I could research more if I knew what these pins are called.
Edit: Answered in the comments: They are turret pins where you wrap a wire and solder to.
MXJ means the connector was made by Molex, in Japan. If you measure the exact pitch, then look on the Molex website for connectors with that pitch, you can hopefully find the appropriate mating connector for your application.
I pulled this from a random Molex shrouded header datasheet:
Notice "TRADE MARK" notation on the center-left.
Those will be under the "Rectangular Connectors" heading of the connectors section of their catalog. This is one instance where thumbing through the catalog is easier than the online version. Check out the Molex SL Connectors on page 1623. More generically known as .100 inch headers.

As mentioned in the comments, those swaged turret pins.
They are used to connect heavy guage wire to PCBs.
The pin itself is "swaged" onto the PCB - it is rather like a rivet.
The swaging provides mechanical strength. The pin can also be soldered to the PCB to ensure a good electrical connection.
You can solder wires to the pins to connect things to the PCB. You can also use clip on wires (alligator clips and similar things) to make temporary connections. Oscilloscope probes will clip onto them as well.
They probably aren't much good for radio frequency stuff. There's no way you can really make connection with a given impedance with them.
