Crimp tool for HiRose DF52 connector

[kvikramg]

Hi Everyone,

I’m planning on using HiRose DF52 series connector on a few of my projects. They are board to board connectors, very small profile.

Here is a example of the connector cable side

connector card side

DF52-2S-0.8H(21) | Digi-Key Electronics

and the actual crimp

DF52-2832PCF | Digi-Key Electronics

The tool HiRose recommends is this

AP105-DF52-2832P | Digi-Key Electronics

Its 6500$ , and i’m not ready to invest that much yet. I’m mostly prototyping so I’m not crimping at volume yet. Does anyone know a small and cheaper handtool that i can use to crimp this connector.

Thanks

There are some universal tools that you could look at such as the PA-09 or the WM9999-ND, however these are what they are universal and there is no guarantee that you would get the crimp specified by the manufacturer like if you were to use the MFG recommended tool.

Many contacts (terminals) for narrow pitch (1.5-2.5mm) JST, Molex, Amp, JAE, and Hirose (HRS) housings require specialty crimping tools. Take, for example, the JST part number SSH-003T-P0.2-H where the manufacturer suggests the hand crimping tool YRS-859 at a cost of over $1,000 USD. This production grade tool’s price tag often puts these great connectors out of reach for a prototyping engineer, hobbyist or maker. One solution to this issue is to look in the Jumper Wires, Pre-Crimped Leads cate…

Thanks for the prompt response and recommendation Robert. Unfortunately WM9999 is too big. The PA-09 looks promising , DF52 isn’t in the compatibility list , however it does support other 30-32 AWG crimps , so it might work. Regardless its a nice addition to my tool box.

I don’t mind buying ready made cable assemblies, if there is a 5 conductor DF52 cable assembly I can work with that.

I was wondering if anyone found any successful alternatives?
I tried with the YRS-859 tool, but it needed some adjustment first and even then at 28AWG die, it didn’t crimp down the insulation tabs and could not insert into the housing. Crimping at the 30AWG die did close them slightly more and squeezing with needle nose pliers I was able to insert the contact. This was very difficult with the fact that they are SO small and the slightest deformation can damage the housing very easily. Pic of a 28AWG crimped.
