Oiyagai 20 Set 3-Pin 5.08mm Pitch Male Female PCB Screw Terminal Block

These connectors are quite nice. I purchases both the 2 pin and the 9 pin connectors and intend to purchase more. They are strong and grip the wire well and are mechanically well made. They are tight and snap together well so I do not expect wiring connection problems such as intermittent contact. (I am still working on my project.) Also important to me was that for a 0.200 pin spacing (5.08mm) a number of the connectors can be placed end to end (stacked or strung together as the length of each connector is exactly an integral multiplier of the pin spacing. Hence, one does not have to leave any dead space between of connectors. I need to to have about 30 screw connector positions and they stacked fine. Most of the connectors that are on Amazon have extra material at the ends and so will not string (stack) together. Another review mentioned that the pins are 0.040" square and so do not fit in a 0.040 diameter round hole, which most proto-board are suppose to be designed to. This is indeed the case and so one either forces the pin through the hole or has to resize the drill hole. A #54 drill bit at 0.055" works well for enlarging the holes at the expense of lost of the through connection material. I found a very nice, clean, proto-board that had well defined holes and solder pads worked well for this re-sizing of the holes and re-drilling went smoothly. https://www.amazon.com/gp/product/B07FK41NG8/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 For some reason a typical broad search on amazon does not bring up these boards, but the supplier site will with some searching.

These terminal blocks are well made and the wires attached firmly. I especially like the quick disconnect connecting block that makes these terminals easy to swap out another device without unscrewing all the wires. I would definatley recommend these for connecting lots of wires to an electronics project/device.

Just as advertised

Got these to put aftermarket air assist on my omtech 60 watt laser. Fits like a glove in the controller. It is easy to install. Just wish I could have bought one...

Based upon initial use, these work well. I am happy with this purchase - thanks.

Product was as advertised. Worked perfecty

Good quality pins was too large for my application but would recommend. Just make sure they are the right size for your aplication.

The ones I received are EXUUNN EX2EDG-5.08, and the quality is great! I will definitely order these again in the future.
