content: Phoenix Contact CK1.6 series pins. To be used to connect to various wire gauges up to 20 AWG (0,52 mm^2). Circuits will carry various signals (milliamps) and one will carry 250 vac @5A. I am replacing failed connector pins so cannot choose alternative styles or manufacturers.This is my first experience with crimp pins that are not "W"-type. The back end of pin is just a turned cup. Crimping tools is US$750 which, if crimping these is your livelihood, would probably be a great deal but I need to crimp just 20 so not economical for me.Is there a reliable means to crimp these that doesn't require the manufacturer's tool?Thanks.

content: There are crimping tools that have 4 plungers that come in from 4 sides. That is what is needed for this type of pin. You might be able to find one at an electronics surplus store for $10 or so. You will have to make up a spacer or some other thing that sets it to stop and release when the plungers have reached the right depth.Otherwise, your choice might be to solder them.Jon

content: Commonly called a "Deutsch" or "Deutsch-style" tool.I've seen cheap ones with adjustable pin & crimp depth in the past, but the link I bookmarked no longer works - and now I can only find $350+ adjustable ones

content: If it's a one-time thing, maybe find a friendly avionics tech (or airplane homebuilder) who may have the needed tool as such crimp pins are common in avionics. (Though the specific die you need may vary by pin or wire gauge.)If you're in the Cambridge, MA area, I have such a tool and a variety of dies, but wherever you are, there's probably an EAA chapter nearby.

content: You're looking for an appropriateCircular Indent Crimp Tool.I don't know where you're located, but here's an inexpensive one:Deutsch Amphenol 4-Way Indent Closed Barrel Terminal Crimp Tool 12-20 AWG. There are others, watch the wire sizes as they're not all the same. Some are rated for 20 - 26AWG, usually red grips, and these will probably yield better results in your case.If you've a lot of these to do (or D-sub/RS232), then you might be better off looking for a decent one made by Daniels Manufacturing Corp. Do note these use locators that have to be selected based on the pin being crimped.Warning: If you look at new prices for these ^, you'll probably get a nosebleed.

content: Harting uses these pins as well. It's a split hexagon that the pin is squeezed between.The prices of new tools range from 200 to 700 euro. Yours is 500 (CRIMPFOX-1,6/2,5-ED-4,0 - 1687419).Using the wrong tool can result in very poor connection, loose cable, over-tightening causing it to crack and other quality problems. If you do not have any tool you could try soldering.

content: If it's a one-off I'd certainly recommend soldering. Make sure you have some kind of strain relief for the wire though, as it will be liable to fatigue at the point where the cores start to be soldered together.
