DMX RGB controller and leads

What are you trying to do? What do you have ? need? All I see is a photo of something you asked for an equivalent. Is it no good?

They are powering RGB LED lights around an Grosvenor casino floor sign , the DMx leads were accidentally stripped out and thrown away now they've realised the floor display doesn't light up. So I'm left with disconnected Controllers , a bunch of 6 core cables snipped and left in trunking , Either I try to get the existing controllers working and get new DMX leads or find an equivalent . To be honest I'm inclined to go with the former but I'm having trouble finding a plug and lead for the LED

I'm no expert in DIN plugs but it seems Mouser and Digikey will have stock when you find a good match with pigtail wires maybe. > Just ask them. key, pin diameter, (1A?) etc need to match

Try your local disti's like RS, but I give low odds on them.

The LED sockets seems to be a standard 8 pin DIN socket. It is not a "mini DIN" socket. Standard DIN normally do not have a latching mechanism, whereas mini-DIN usually does.
Ones like:
Note that there are 2 types of 8 pin DIN plugs, each with slightly different degree offset for the pins. Normally it is the 270 degree plug unless something special is required.
