hello,

im looking for a connector to connect my arduino mgea to the 4 pins on a parallax RFID reader..

my problem is i dont know where to start since i dont know the exact measurments of the pins on the reader. all
i know is that they are 0.1" (2.5mm) apart.

Can anyone help. maybe links to purchase site??

thank you for the prompt response...

The break away header pins are a great idea. never thought of that... it will be usefull for my keypad.

but my original thin gis i only wanted a 4 conductor cable the link you provided is 6. i can find allot of 6 and 3 but no 4... should i just use the 6 and ignore the un-used pins??

Get some alarm wire from home depot. It's GRBW- green red black white. Put female headers on both devices.

Or yes, ignore the 2 end pins on a 6 conductor ribbon

Look on ebay, plenty of 4 pin, quite cheap too

Hi,
Take a look about Arduino cabling here: http://arduino-info.wikispaces.com/Cables

There are lots of low-cost cables here: http://goo.gl/dMEIp

Here's an example with your type sensor:

That actually the wire i am useing well not alarm wire exactly but i am using a 2 pair 20guage wire that i got from a guy that does ADT systems. The femal headers will work for the keypad yes since it ha the through hole connector on the bottom, but the RFID has 4 pins. i need something to connect it such as a plug that will wrap the 4 pins. terryking gave me a link but the item is sold out... it would have worked perfectly..

Just get the 6-pin connectors and don't use two of the pins. That's life, man - don't let the perfect become the enemy of the good.
adafruit has an assortment (40 for $6, that's 15c ea.) of single-conductor connectors available, too. You probably need some other stuff and could round out your order.
