I have some current sensors that I need to mount close to thebatteries on my boat whose current they are monitoring with thedisplay and electronics quite some way away at the helm.The obvious approach is to mount the sensors on a little bit ofveroboard or similar (their pins are 0.1" pitch) and then to run somecable from there to the electronics. In addition it would be nice tobe able to disconnect the cable easily for installation etc.I need 8 wires from sensor to electronics so the obvious cable to useis UTP/ethernet, cheap and reasonably robust. (N.B. it's not carryingany load current, these are hall effect sensors with no connection tothe circuit whose current is being measured)However, and here's the problem, I can't find any RJ-45 sockets whichcan easily be mounted onto veroboard (or any other 0.1" pitch board)as every single RJ-45 socket I can find has the connections laid outas two rows of pins at 0.1" pitch between pins but at 0.05" offsetbetween the two rows of four pins.So can anyone suggest a way of connecting (in a removable way) UTPcable to a piece of veroboard? I've tried the following approaches tofinding a solution but unsuccessfully so far:- Looking at many, many types of RJ-45 socket to see if there's one which can mount on 0.1" pitch board. Looking for prototype/veroboard which has either a general layout which can accomodate an RJ-45 socket or one which has specific RJ-45 socket pads. Plugs/sockets other than RJ-45 which could do what I want, i.e. mini-DIN or similar.Any suggestions would be most welcome. I could of course simplesolder the RJ-45 direct to the veroboard (and tie it mechanically ofcourse) but that would be much less convenient for installation andtesting. Solutions using PCB header/connectors are possible but don'tsuit UTP particularly well.

Some of this:- you eight cores as four screens and four centres.This:- very nicely onto 0.1 inch veroboard.

Electronics DIY, how to mount/use an RJ-45 socket on veroboard or similar?

I'd get an RJ45 socket with a metal shield, that can be soldered to. Drill out the board (eg a pilot hole filed to make it rectangular) to leave a space for the pins to poke through without touching anything. Solder the shield to the copper traces (with enlarged holes if necessary) so that it's mechanically secure. Then run short wires from each pin to the relevant copper track. Once it's electrically OK and mechanically secure, fill in the hole with epoxy to stop anything snapping later.

well drill the veroboard then

The amount of work some peple go to to avoid doing any work...

TAKE ANY RJ45 SOKET. SOLDER WIRES TO IT. INSERT WIRES IN BOARD GLUE SOCkET ONTO BOARD WITH EPOXY.

SHEESH.

suitable tracks

But the OP wants to connect 8 wires - hence the RJ45 discussion.

So why are you blathering on about a 25 way D type?

A 9 way D works - and that's all that was needed.

But you appeared to be replying to the post about "I have the same problem with D-type connectors". :-)

However, as the OP, I agree a 9-way D-type would be a reasonable solution for my requirement. Not quite so neat or easy to put a D-type plug onto my cable but not too bad.

Thanks for the idea.
