Lemo Cables - A new approach?
by Sadek
Hello community!
Lets face it, we love
Lemo cables but I would claim that there are mainly two
reasons why people are hesitant to buy them:
price
availability
I
love the look of the RAMAWORKS standard USB cable but I also
love Lemos. Boom, there you go.
I came up with the
simple idea to solder a standard factory-USB-C Cable to a
China-Replica Lemo connector. But why?
Reduces price by
half of what lemo cables go for
Easy to manufacture and
is without a doubt suitable as an in-stock product
Furthermore:
No
cheap looking heatshrinks anymore (subjective)
0B Lemo
which gives a cleaner and more elegant look than his bigger
brother 1B
USB-C and USB Mini Connector out of the box,
no extra order

IC Form:
https://forms.gle/AN92hxPJWiXDFxgEA
I have two Prototypes:
Silver Lemo 0B 5pin with
a black nylon USB-C to USB-A cable
Black Lemo 0B 5pin
with a black nylon USB-C to USB-A cable
I don’t have a
Mini USB cable Prototype on hand because the MOQ for a Mini
USB cable in the same style as the USB-C one is 1000 pieces.
I wanted to gauge the interest of this product before a make
such a big order but I will of course provide a render.

I love the results of the product but I don’t know if
anybody other than me likes this, thats why the IC and the
hesitation to make such a big order.
If the IC gets
enough positive feedback I will order a Mini USB Lemo right
away.
Price
The prices below are estimated. They can
decrease, but not increase , this is the worst case scenario
price. The prices will most likely drop a bit.
If IC
reaches GB:
Sale Type: in-stock FCFS
Units: TBD
Sale
date: TBD
Shipping out of EU. If requested I can
hopefully work with vendors in your region. (need feedback
first to answer this)
Silver Lemo 0B 5pin with a black
nylon USB-C to USB-A cable : 45(Estimated)
Black Lemo
0B 5pin with a black nylon USB-C to USB-A cable:
45(Estimated)
Silver Lemo 0B 5pin Set with a black
nylon USB-C , Mini USB, USB-A cable : 65(Estimated)
Black
Lemo 0B 5pin Set with a black nylon USB-C , Mini USB, USB-A
cable : 65(Estimated)
Detailed information
Length:
1.6m(5.24ft)
Powers all keyboards to 2A max.
USB
2.0: I chose 2.0 because it is easy to solder 4 pins. USB
3.0 would be a nightmare to solder.
The USB-C End is
20cm(7,87 inch) long: measured from the tip of the USB-C
connector to the end of the Lemo Plug its soldered on.
Cable
outer diamter Ø4mm. Thick and easy to straighten.
All
Lemos are made out of brass and are almost indistinguishable
from the real ones, they feel and look great.
Black
Lemo GB unit will have red dots instead of white. My
manufacturer did not have them in stock.
For better
understanding I would recommend to look at the full album. I
explain everything with references/pictures.
Notes
I
don’t claim that this is a revolutionary idea but I love the
results and I hope you like them too.
My criticism
towards heat shrinks is as follows: there is nothing wrong
with a well applied heatshrink, but in my opinion a shell
looks much cleaner and that was one of the reasons why I
came up with this product. I love the look of the RAMAWORKS
standard USB cable but I also love Lemos. Boom, there you
go.
I state that 0B looks cleaner and more elegant than
1B. I don’t have any data that backs this up this is once
more my perception and purely subjective.
If this sale
happens it will be commercial sale. I am a registered
one-man company in Austria.

Update
Hey guys thank you for all your
feedback! The results of the IC form are in and I derive
from them:
- that I should remove the logos
- shorten the cable of the usb c end
- give an option for coiled cables
-
make more colorways
Logos
Almost half of the people who filled out the form requested that I should remove the logos. A minority on the other hand loved them.
Nevertheless I decided to remove the logos completely, the USB shell will be blank like this:
Cable length
The length on the USB-C end will be shortened to 13cm. Not to confuse anyone I mentioned in my original post that the USB-C end is 20cm long. However I measured from the very top of the lemo to the tip of the USB-C, which was wrong and useless.
These measurements are the right ones:
Coiled cables and more colorways
Unfortunately I will not give the option to get a coiled version. I want to keep the variants low since my budget is limited and the MOQ for different colorways for both cable and lemo connector is very high, my mistake.
For now the colors stay the same.
I was working on a new colorway but the MOQ for the custom colored Lemo is 500 Sets. Since this is an in stock sale I can not pay for such a big stock upfront.
But I will definitely bring more colorways , if the first run turns out successful.
Vendors
I will work to get a vendor in the US and EU. The demand doesn’t seem that high for other regions. Sorry, for my scale of production it won’t be worth it.
The sale could take place on Amazon US/EU since I am already familiar with the system. But nothing is set in stone for now. I need to get feedback to the changes.
Are you guys happy with the changes? https://forms.gle/EuH4nqKBanwzaAgv5
