| You need to examine the end result under a decent magnifier. The contacts that get pushed down between the plastic lands should be just slightly below the top of the lands. Drag out a bunch of factory crimped jumpers preferably from different manufacturers and get a feel for what normal looks like.
The cheap crimpers don't seem to have any adjuster and some of the expensive ones do have an adjuster for the when the ratchet releases but the bottoming out setting of the crimper is machined into the die. On those, it is important not to keep squeezing after the ratchet releases.
Some people want to give it that EXTRA squeeze for good measure. BAAD idea. I had a 3rd party installer make all his own jumpers for a network I had a support contract on. I had to get tough with the client and refuse further support until all the jumpers were replaced. It was an ugly sight... toothpicks stuck in the jacks to hold the plugs against the contacts... PCs fading in and out like skip radio.
Oh, and not all RJ45 plugs are created equal. there are three basic types.
One for stranded with a pointed (usually 2 of them, inline) insulation displacement cutters (IDC) that peirce straight down the centre of the wire.
The type for solid where the IDC is forked (3 cutters, offset) to straddle the wire.
A third that is universal, also forked.
If you use the stranded type on solid, it will not give you a lasting connection. |
