(12 customer reviews)

4,95 incl. VAT/BTW

50cm service jack cable as included with the Gateway products.

One side has a straight plug, the other side is angled.
Both plugs are extended so they will fit all boilers.

EAN: 4043619855643 SKU: ems-service-cable-50cm-angled Category:


This is a high quality EMS service cable for connecting the Gateway or interface board to the service jack connector on the boiler or heat pump.

It’s the same type of cable as optionally delivered with each Gateway product.
The length of 50cm is perfect for most boiler. for heat pumps it is often too short to mount the gateway outside of the housing.
We also have a version with 110cm length here.

This cable will fit all Gateway models and all interface boards ever sold by me.

Lot’s of EMS boilers have a service jack with a recessed connector.
This means not all jack plugs will fit properly and you can shortcut the bus.
This cable has extended plugs on both sides, so it will always fit.

The EMS Gateways are also powered via this jack cable.
Because of this the copper wires inside the cable need to be thick enough to handle the current.
Cheap jack cables are only intended for audio and these have way too thin wires inside, which may cause a fire hazard.
This cable has been verified to work well with all EMS Gateways and interface boards.

Some boilers have the service jack connector behind a plastic panel.
Because one side of this cable has an angled plug, you can still close the panel with the plug inserted.


  • AWG24 copper wire
  • 50cm length
  • color black
  • extended plugs
  • one side straight plug
  • one side angled plug

Not all boilers have a service jack. If so, it’s usually positioned on the front of the boiler near the display.
Almost all heat pumps have the service jack on a cable on the inside of the housing.
See the wiki for more information.

This cable does not fit old iRT boilers like the Ecomline. Only use it with EMS boilers and heat pumps.
