S7-1200 G2 wiring harnesses, plugged in before the panel ships.
Pre-fabricated harnesses for every SIMATIC S7-1200 G2 CPU, signal module and signal board — G2 push-in connectors that match the Siemens connector color and coding key, ferruled and labeled leads with the signal name at both ends, continuity tested, bagged with a part number you can read. Pick the modules in your rack, choose length and gauge, and add them to the cart.
CPU 1212C, 1212FC, 1214C or 1214FC in AC/DC/Relay, DC/DC/Relay or DC/DC/DC. All three connectors come with it.
Signal modules and signal boards from the G2 range: DI, DQ, relay, AI, AQ and mixed I/O.
1, 2 or 3 m leads in 18 or 20 AWG, per harness or for the whole rack in one click.
Each harness is a real shop item with its own part number. Check out, or send the build sheet for a quote.
Landing wires on a G2 plug is the slowest job in the panel.
G2 push-in connectors matched to the Siemens terminal: gray with no key, orange type-A for AC power and relay outputs, light gray type-B for analog. It only fits where it belongs.
- Push-in, tool-free
- Coded keys
- Siemens pinout
Every conductor carries a printed sleeve with the Siemens signal name at both ends and an insulated ferrule ready for the terminal strip. Colors follow NFPA 79 so the harness drops into a UL 508A panel as-is.
- Signal-name labels
- Insulated ferrules
- 100% continuity
TPC + the Siemens MLFB + connector + length + gauge. Read it off the bag, off the drawing, or off the harness itself, and reorder the exact same thing next year.
- MLFB-based
- Stock the spares
- Same shop, same price

Pick the modules, we build the harnesses.
Choose your S7-1200 G2 CPU and any signal modules or signal boards. Every wiring connector shows up with its pinout, a Think-PLC part number and a price. Set the lead length and wire gauge, then add the harnesses straight to your cart — they are real shop items, built to order in our panel shop.
Choose your CPU
Every G2 compact CPU has three plug-in connectors: X80 power, X10 digital inputs and X11 digital outputs. Pick the power / output flavor you have and all three land in the rack below.
Add signal modules and signal boards
Signal modules (SM) mount beside the CPU and carry two connectors, upper X10 and lower X11. Signal boards (SB) snap into the CPU front and use one X19 connector. Add as many as your rack has.
Length, wire gauge and quantity per harness
Untick any connector you wire yourself. Each harness is priced on its own: plug, populated conductors, ferrules, labels and test. Odd pins run along the top of the plug, even pins along the bottom, exactly as the Siemens manual numbers them.
The part number system read any harness from its label
| Segment | Example | Meaning |
|---|---|---|
| TPC | TPC | Think-PLC pre-fabricated connector harness |
| Module | 6ES7214-1AF50-0XB0 | The Siemens order number (MLFB) of the module the harness plugs into — CPU 1214FC DC/DC/DC here |
| Connector | X80 · X10 · X11 · X19 | Which wiring terminal on that module: X80 power, X10 upper / inputs, X11 lower / outputs, X19 signal board |
| Length | 1M · 2M · 3M | Lead length from the plug to the stripped, ferruled ends |
| Wire | 18AWG · 20AWG | Conductor size, UL 1015 MTW stranded |
So TPC-6ES7214-1AF50-0XB0-X10-2M-18AWG is the 16-pin digital-input harness for a CPU 1214FC DC/DC/DC, two meters long, in 18 AWG. Need another length, a different gauge, shielded analog pairs, a different far-end termination, or a module that is not listed? Use the quote request — it is the same shop.
What every harness includes and the wire colors we use
G2 push-in connector matching the Siemens connector color and coding key (gray no-key, orange type-A, light gray type-B) · only the populated positions are wired · insulated ferrules on both ends · printed sleeve label with the Siemens signal name at both ends (DI a.0, 1M, L+, DQ b.1 ...) · spiral-wrapped bundle · 100% continuity tested · bagged and tagged with the part number.
Conductor colors follow NFPA 79 / UL 508A so the harness drops into a listed panel without re-marking:
Relay outputs switching DC, or a house color standard of your own? Say so in the notes and we build it that way at the same price.
How the price is built every rate the tool uses, in the open
The price on each harness is the web-shop list price of that exact part number. Freight and sales tax are added at checkout. Account customers and OEM partners: request the quote instead and your pricing is applied.
