Sometimes there’s only a 2-millimeter difference between two perfectly usable parts—and that’s exactly where the
E-Stim Systems 4 mm to 2 mm Adapters come in handy. These compact adapters make it possible to connect an e-stim cable with
4 mm banana plugs to electrodes with a
2 mm connector. You’ll receive two adapters, so both ends of a standard two-pole 4 mm cable can be adapted.
Each adapter has a
4 mm socket on the cable side and a
2 mm plug on the electrode side. This allows them to serve as a simple bridge between two commonly used connector sizes in electroplay. No need for a new cable when the connectors don’t match—two small adapters are all it takes to make the difference.
From a 4 mm cable to a 2 mm electrode
It works simply. Plug the
4 mm banana plug from your cable into the 4 mm socket on the adapter. On the other end is the smaller 2 mm pin, which is then inserted into the 2 mm socket of a suitable electrode.
The adapter only changes the size of the physical connection. It does not generate an electrical signal itself and does not alter the settings of the connected e-stim controller.
This makes this set especially handy if you already have a good 4 mm cable but also want to use electrodes equipped with smaller 2 mm connectors. It’s a small piece of technology that prevents a difference in connector size from getting in the way of an otherwise perfect combination.
What’s the difference between 2 mm and 4 mm?
When it comes to adapters, product names can get pretty confusing. E-Stim Systems also sells an adapter that works exactly the other way around.
This
4 mm to 2 mm adapter is intended for: If, on the other hand, you want to connect a cable with a 2 mm/TENS pin to an E-Stim electrode with a 4 mm socket, you’ll need the other version: the
TENS/2 mm to 4 mm adapter. The difference may seem minor, but when ordering, it saves you a lot of confusion alongside the power box.

Note regarding 2 mm and TENS connectors
E-Stim Systems makes an important note regarding the term “2 mm.” Not every connector sold as a TENS connector is exactly the same size.
Many TENS devices use a pin measuring
0.080 inches. That’s very close to 2 mm, but it’s not exactly the same. According to E-Stim Systems, this means the different versions can’t always be combined without issues.
Therefore, when using equipment from other manufacturers, check the exact connector type beforehand. These adapters are specifically designed for a
true 2 mm socket on the electrode side.
Handy to have as a spare in your e-stim collection
Anyone who combines different electrodes, cables, and controllers will quickly notice that not every manufacturer uses the same connector. E-Stim Systems uses robust 4 mm connectors on many of its metal electrodes, while smaller 2 mm/TENS connectors are also common in electroplay and TENS-related accessories.
A pair of adapters takes up hardly any space and gives your existing 4 mm cable more connection options. They’re a bit like the travel adapters for your e-stim collection: not very exciting to look at, but incredibly handy when two different worlds just don’t quite connect.
Connecting Safely
Turn off the e-stim controller before connecting cables, adapters, and electrodes. Make sure the plugs are securely inserted into the adapters and that the 2-mm pins are correctly positioned in the corresponding electrodes.
Next, set the intensity to the lowest setting before activating the controller, and increase it gradually. E-Stim Systems recommends using electrostimulation below the waist, avoiding the head and neck, and avoiding electrical pathways through the chest area. Do not use electrodes on damaged or irritated skin.

FAQ
What is the E-Stim Systems 4 mm to 2 mm Adapter used for?You use the adapter when you want to connect an e-stim cable with a 4 mm banana plug to an electrode with a 2 mm socket. The 4 mm plug fits into the adapter; the adapter’s 2 mm pin then fits into the electrode.
How many E-Stim Systems 4 mm to 2 mm adapters are included?You’ll receive two adapters. These allow you to convert both 4 mm plugs on a compatible two-pole cable to a 2 mm connection.
Is the E-Stim Systems 4 mm to 2 mm adapter the same as a 2 mm to 4 mm adapter?No. The connection orientation is exactly the opposite. This version has a 4 mm socket and a 2 mm plug. E-Stim Systems also sells a separate version that allows a 2 mm/TENS pin to be connected to an electrode with a 4 mm connector.
Does every TENS connector fit the E-Stim Systems 4 mm to 2 mm adapter?Not necessarily. Some TENS devices use a 0.080-inch connector instead of a true metric 2 mm connector. The sizes are very close, but E-Stim Systems warns that they aren’t always fully interchangeable. Therefore, check the exact connector on devices from other brands.
With the
E-Stim Systems 4 mm to 2 mm Adapters, a slight difference in plug size won’t limit which electrodes you can connect. Two compact adapters, surprisingly practical. Your order will be shipped quickly and in completely discreet packaging.
