Electronic sources
Posted by ndbprr on Thursday, December 26, 2019 5:53 PM

Need some correct names and sources for the following items:

1. The wire used to daisy chain the controller plug in  stations (bulk not premade)

2. The connectors for that wire

3. The tool to fasten the connectors to the wire

4. Led color and size for headlights and resistor size

5. Decoder connection wire

 

Thank you

When the local electronic parts stores and train hobby shop closed here in Bakersfield I was forced to go to mail order.  With the free shipping option on eBay that has worked for me for the last 8 years.

5. Decoder connection wire

I'm happy with this:

and for more colors:

Diditrax sells a nine-wire by ten feet selection as well but the Amazon stuff is a bit less expensive:

3. The tool to fasten the connectors to the wire

I have an Ideal RJ12 crimping tool but I don't see the exact one but it is very close to this Klein model:

 Are you talking Digitrax? Here are instructions for Loconet.

 RJ12 connectors: 6P6C  Six positions, Six conductors

 6 conductor flat wire:

Sometimes it is cheaper to buy made up phone extension cable and cut to the length you need and attach a plug when needed.

Good Luck, Ed

 1, 2 & 3  It may or may not vary by manufacturer of the DCC system.  I'm sure Randy knows, but I don't.  We just had a thread on NCE.  The tool would be a crimper, but they are often specific to the number of wires in the cable.

4 Warm white 3mm led, 1000 ohm resistors, work for my period the transition era.

5 Decoder connection wire generally 30 ga, available in packs of the appropriate colors from Litchfield Station or Tony's Trains.

Sources depending on what you need for cable and tool, you may be able to buy it from Home Depot or Digikey or Mouser Electronics on the web.  Yes I have bought cheaply from Ebay China sources, but given what I have read recently on involuntary organ donation, I can no longer justify doing so.

are you asking about the rj-12 cable connecting one UTP to another?   if so, 4 conductor flat cable is easier to attach connector to.

I have been using 3mm LEDs for headlights, as I model the early 50s I use Warm White LEDs for the 50s look.  Bright White would look better in newer locomotives.  I use the standard 1000Ω ¼ watt resistors for headlights, much higher value for interior lighting.

I go with wide angle Warm White LEDs for interior lighting at very low current, normally 4700Ω to 10000Ω ⅛ watt resistors.
 
 
 
I’ve been buying #30 AGW wire for my decoder wiring in my locomotives.  #30 only has .02 volts loss at 500ma for 12” length.
 
I’ve been buying the #30 wire off eBay for several years and never had any problems even with my dual motor articulateds that can draw up to 1 amp with both motors stalled.
 
I like the Silicon Super Flex wire as is never breaks with lots of flexing.  I use #24 AGW Super Flex for between the trucks incase a short appears at a loop, I do not use auto reversers as I run dual mode DC or DCC.
 
The #30 AGW is .8mm outside diameter, the #24 AGW is 1.6mm outside diameter.

While we're on the subject of fine high-frequency wire, here is a handy PDF table of Litz wire that may be a useful resource.

 The wire used for NCE and Digitrax is often referred to as RJ12 but that isn't an actual specification - it's really RJ11 6p6c (6 pins, 6 conductor). NCE only uses 4 of the wires, but trying to put 4 wire cable in a 6 pin connector is asking for trouble because it's easy to offset it, and then things won't work. There are no issues having all 6 wires in the plugs for NCE. 

Here are the ends:

Here's the cable (though you cna go elsewhere and get less than 1000 foot spools)

https://www.monoprice.com/product?p_id=956

Here isa  good crimp tool. Don't skimp on the crimp tool. This one strips and uses a ratcheting action to ensure a good crimp

 Since I hard wire most of my decoders, I often have plenty of cutoff wire sections, but I picked up this to have extra:

https://yankeedabbler.com/ho-scale-dig-dcdrwire-decoder-wire-acc-decoderwire-9-conductor-?gclid=CjwKCAiA9JbwBRAAEiwAnWa4Q9irJt0ivQIMo7_wIGN_1fmzitXm6c-6fG2l-ZExDWHicPG9aqimKBoCvBQQAvD_BwE

For headlights I use golden white LEDs for first gen diesels. A variety of sizes depending on the loco. Mostly the 3mm size, but for some the 5mm size fits in place of the original incandescent bulb. I don't need ditch lights or anything for my era so I have no need of tiny surface mount LEDs, yet. I usually get the miniatronics ones (but the resistors they come with are too low, use 1K minimum). You can get much cheaper ones on eBay, but try a few, there's a lot less control over light color and quality with the cheap Chinese ones.
