    Hi Wendy

     

    What is really unique about Harwin's datamate products?

    Hi Véronique,

     

    Here is a summary of why Datamate is so special:

     

    Datamate is an Industry-recognised high performance connector system, which is better value than Mil-spec connectors, giving a very high performance for the price.  The range features cable to cable, cable to board and board to board variations, and also has a wide range of jackscrew or latching options to give additional strain relief.

     

    The system is rugged & robust, and has excellent levels of vibration and shock resistance and current rating, for such a compact footprint (2mm pitch).  We have many variations of vertical, horizontal, crimp, signal, power and coax, and new variations are being added to the range on a regular basis, with future expansions already in progress.

     

    Typical customers for this range include Boeing, Airbus, NASA, BAE Systems, Thales, Delft University (for Nano-satellites), Warwick University (Search and Rescue Robot), Formula 1, Rolls-Royce Engines...

     

    We can also offer Live Technical Support online at Harwin.com and Element-14 (me ) , and have technical documentation and 3D CAD models on our website.

     

    We believe that the Datamate range is highly versatile and excellent value, and I think many of customers would agree.

     

    Feel free to ask any more questions!

    Hello Véronique,

     

    Hedley Fletcher ( Harwin regional sales manager) said to us, that the performance was the high reliability four finger beryllium copper contact .

    Is it right Wendie.

    Hi Nicolas,

     

    That is correct, the Four Finger Beryllium Copper contact really is the heart of this connector range.  The four fingers (in combination with a round mating pin) give great vibration resistance in any direction, the Beryllium Copper gives good performance up to +125 degrees C, and the material choice also gives excellent number of high mating cycles (we have tested up to 5,000 with no loss of electrical performance).

    Hi

    I am using some standard harwin connectors that require a 2MM strip length.

    Since this is hand work, Do you know of any (good) tools that do repeatable strip lenghts.

    I have seen OK and CK tools (same guys?) but it looks like those two are just for solid wire.

    Thanks JB

    I talked to our Quality team, as they do the most wire stripping in the company for testing purposes.  They currently use a couple of CK tools (they got these from RS, sorry Farnell!), that look like these two items: 44878984487898 and 44879044487904.  The RS part number on the tool was 662721, so please feel free to have a look at all these.

     

    They did say that you do need to be careful not to be heavy-handed with it, otherwise you can take a strand out - and that, with the PTFE wire we use, it's not essential to cut all the way through, you can cut most of the way and then pull the stripped piece off.  It's probably worth experimenting to get the right setting for any wire size that does not quite reach the conductor all the way round.

     

    I would think that if you are doing any significant volume, it's time to move to a semi-automated piece of equipment.  I'm afraid I don't have any specific recommendations in that regards, as we do not strip wire ourselves in that sort of volume.  Perhaps a cable assembly specialist could make some recommendations?

     

    If there are any wire stripping experts out there who can contribute, do please feel free to do so!

     

    I hope this helps, thanks for the question!

    Thanks Wendy!

    We might look into a automated striper. In the mean time I have found a Stripmaster light, that does a good job. That with a 2mm gauge I can do the connectors proper.

    Joseph,

     

    Excellent!  I'd love to have any info you have on that tool (where you got it from, or who makes it), so that I can recommend it for other users?

     

    Thanks

    Hi Wendy,

     

    I need a PLCC which is compatible with this socket:

    http://il.farnell.com/3m/8484-21b1-rk-tp/socket-ic-plcc-84way/dp/1183025

    Basically I need the chip carrier to meet these requirements:

     

    1) Number of pins: 84

    2) Body size: 1.15inch X 1.15inch

    3) Cavity size: 1.4cmX1.4cm (approximately 0.55inch X 0.55inch)

    4) conductive bottom - I mean the bottom of the cavity, and not the back side of the chip carrier

    5) Pitch spacing: 1.27mm (0.05inch)

     

    Do you have an idea from where can I purchase 10 chip carriers like those?

     

    Thanks,

    Gilad Cohen

    Hello,

     

    I am an engineering student.

     

    For my thesis experiment, I am going to buy this LED http://au.element14.com/ledengin/lz4-00ua10/led-10w-uv-400nm/dp/1678986

     

    The problem is that I do NOT know anything about how to make it work.

     

    I'd like to connect this with DC in order to control the power output.

     

    I would also need mounts.

     

    How would you do it?

     

    Please help
