Electronics-SalonDIN Rail Mount Screw Terminal Block Adapter Module, for Arduino MEGA-2560 R3.

Bought this for a prototype I had to put together quickly. Haven't checked all terminals but from what I did check, quality was good, fitment was good and functionality was perfect. Great way to save time and stay organized for proof of concept projects. Will buy again.

Own two. Very high quality. Worked great in my application. Only criticism is that it is a little pricey. That said, recommend this DIN rail mount

This is a great product. Some of the reviews complain that you can’t see the pin assignments. That’s true but there’s a fairly easy temporary workaround: Unscrew the ends of the rails, and slide the board out, attach wires, and then resecure in the rails.

Nice product perfect for industrial automation.

Very solid feel to this mount. It's plastic but very thick. The Mega fits snuggly onto the pins with the back of the PCB facing outward (as pictured in some of the associated photos). Overall this is a fantastic option for mounting an Arduino Mega board to a DIN rail.

Great mounting board, only constructive add is that when the board is plugged in all the port markings are hidden.

A super solid way to mount a Mega2560 to DIN rail. Rock solid construction and really solid on the rail. The screw terminals are easy to access. The Mega2560 mounts component side down, so be prepared. There is a reset button and ICSP pad pattern that are accessible with the board installed. Otherwise there is no access to the component side when it is installed.

This product is good except it is not what I thought I was buying. You can see in the posted picture that there are markings on the terminals. That is what I thought I was buying. The one I recieved had no terminal markers. The purpose of buying something like this is to make the Arduino easier to wire and make it look more neat. The other issue is you cant contact the manufacturer easily and I am sure they won't send me the labels.
