FUN but REAL: Fundamentals of Newton‘s physics in ruins

Scientists helpless – engineers laughing. Some of our SOS electronic customers performed a feat of derring-do. They connected a connector with height of 9,32mm (RJ45 plug) to a printed circuit board with construction height of 7,75mm.

Where did those mysterious 1.57 mm disappear? We know the answer

It’s easy – we’re in negative dimensions Join those who defeated physics – use it in your device too: RS3-21001D1A.

There are many devices that we connect to Ethernet with standard connector RJ45. And thanks to IoT the number is increasing. Many times its just simple small boxes and if we didn’t have that RJ45 that determines the construction height of the PCB, they would be even smaller. We bring you a simple solution – because brilliant solutions are simple.

RS3-21001D1A is a standard modular jack 8P8C with integrated transformators and two LEDs. But! It is so-called recessed version:

Characteristics / advantages:

●RJ45 1x1 Tab Up

●T/H, Slim, Sink

●10/100 Base-T

●LED L: Green, LED R: Yellow

●Construction height above PCB: 7,75mm (in comparison with standard 13,5mm resp. 11,5mm for Low Profile versions)

Competition with the following question has been published here:

You have a 11.5mm high connector. How high distance shaft must be used beneath the connector to reach overall construction height of 7.75mm?

The correct answer was: -3,75mm :-)
