45-Inch TENS/NMES Replacement Lead Wires — 2.35 mm Plug to 2 mm Pins, 2/Pack

Replace missing, damaged, loose, or intermittent electrotherapy cables with these 45-inch TENS and NMES lead wires.

Each package contains two lead wires, enough for the two channels on many standard portable electrotherapy devices. Each cable connects to a compatible stimulator through a shielded, right-angle 2.35 mm plug and separates into two standard 2 mm pin connectors for reusable electrode pads.

These replacement wires are compatible with many TENS, EMS, NMES, interferential, Russian-stimulation, and portable combination devices that use the same connector configuration. They are not universally compatible with every electrotherapy unit, so customers should compare both ends of their existing wire before ordering. The manufacturer publishes this product as item WW3005, Standard 45-Inch TENS Lead Wire, 2 Pack.

WW3005 as a pair of 45-inch replacement leads for compatible TENS and EMS stimulators and recommends replacement every four to six months.

A lead wire must match the device connection and the electrode connection. Matching only one end is not enough.

The single end of each cable uses a

• Shielded plug
• Approximately 2.35 mm device connection
• Right-angle or L-shaped housing

The plastic shield surrounds the metal connection as it enters the compatible stimulator.

The opposite end divides into two color-coded pins. Each pin measures approximately 2 mm and inserts into a compatible electrode’s female pigtail or molded socket.

These wires do not connect directly to snap-style or tab-style electrodes without an appropriate, manufacturer-approved adapter.

Most portable dual-channel TENS or NMES devices can operate with one or two electrode pairs per channel arrangement.

The package supplies two wires, allowing both channels of a compatible dual-channel unit to be connected.

A four-channel stimulator generally requires four lead wires for eight-electrode operation. Two packages may therefore be required when replacing every cable on a compatible four-channel device.

Compatibility is based on the device retaining the standard connector configuration used with the original equipment. Customers should still compare their present lead wire and device port, especially when a model has been revised or rebranded.

Yes. These wires use the standard shielded device plug and 2 mm electrode pins found on many portable electrotherapy units. However, compatibility should be confirmed from the connector on the customer’s existing wire rather than assumed from the modality or brand name alone.

The shape of the device plug

1. The diameter of the shielded connection
2. The electrode-pin style
3. The original lead-wire part number, when available

Customers who cannot identify the connector can contact Balego with the device name and a clear photo of the port and original wire.

The electrode end of each wire uses standard 2 mm pins.

These pins fit reusable electrotherapy pads with compatible female sockets, including many pigtail-style TENS, NMES, EMS, and FES electrodes.

Balego TENS/NMES/FES electrodes are available in multiple sizes and use a molded pigtail-style connection for compatible standard-pin lead wires. The electrodes are made in the United States using American-made raw materials.

Available Balego electrode sizes include the following:

• 1.25-inch round
• 2-inch round
• 2-inch square
• 2 × 3.5-inch rectangle
• 2.75-inch round

Browse all electrotherapy electrodes to compare pad size, backing, hydrogel, connector, and package quantity.

“Universal” is commonly used for lead wires with standard connectors, but no lead wire fits every TENS or stimulation device.

These WW3005 wires are not the correct choice when the device uses the following:

• A proprietary EMPI device plug
• Chattanooga Continuum safety cables
• Snap-style electrode leads
• Tab-style electrode clips
• USB-style connections
• An unshielded device connector
• A connection diameter other than approximately 2.35 mm
• A proprietary wearable-stimulator cable

The product should therefore be described as broadly compatible with standard portable electrotherapy units, not universally compatible.

WW3005 wires should not be ordered for an EMPI unit solely because both cables connect to pin-style electrodes. The device-side plugs are different. We have a separate EMPI 193057-100 replacement wire for compatible legacy models.

The Continuum uses its own replacement cable, part 2615. Customers should purchase that model-specific wire instead of assuming the WW3005 connection will fit.

Use this checklist before purchasing replacement electrotherapy cables.

Replacing lead wires approximately every four to six months. Actual replacement timing may be sooner when the wires are heavily used, tightly wrapped, repeatedly bent, pulled by the cord, or exposed to damage.

Replace a wire when:

• Stimulation cuts in and out
• Output changes when the cable is moved
• One channel works inconsistently
• The outer insulation is cracked
• The cable is frayed
• Internal conductors are exposed
• The plug feels loose
• An electrode pin is bent
• The wire has been pinched
• The cable has been chewed by a pet
• The connection cannot be kept clean
• A known-good set of electrodes does not restore reliable output

Do not tape over damaged insulation or continue using a cable with exposed conductors.

Old electrodes and damaged lead wires can produce similar symptoms.

1. Turn the device off.
2. Move a known-good lead wire and electrode pair to the affected channel.
3. Restart at zero intensity.
4. Increase the level slowly.
5. Determine whether the problem follows the wire, pads, or device channel.

Do not swap or reconnect wires while stimulation output is active.

Proper handling can reduce bending and connector damage.

• Hold the molded plug when disconnecting from the device.
• Do not pull the cable itself.
• Hold the insulated pin housing when disconnecting an electrode.
• Keep electrode gel away from the metal pins.
• Wipe residue away with a soft, slightly damp cloth when permitted.
• Dry the wire fully before storage.
• Coil the cable loosely.
• Do not wrap it tightly around the stimulator.
• Avoid sharp bends near the plug and Y-split.
• Store wires in the device case.
• Keep them away from pets, children, sharp objects, and excessive heat.
• Inspect the insulation and connectors before every session.

1. Turn the electrotherapy unit off.
2. Set every intensity control to zero.
3. Insert the shielded device plug fully into the compatible channel.
4. Connect each 2 mm pin to a compatible electrode socket.
5. Apply the electrodes to clean, dry, intact skin as directed.
6. Confirm that the pads have complete skin contact.
7. Turn on the device.
8. Increase intensity gradually.
9. Stop for sharp, burning, intermittent, or painful stimulation.
10. Return intensity to zero before disconnecting any wire or electrode.

Follow the instruction manual for the exact TENS, NMES, IFC, or combination device.

Choose the WW3005 45-Inch TENS/NMES Lead Wire Pair when the device requires the following:

• A shielded 2.35 mm device connection
• Standard 2 mm pin-style electrodes
• One wire per stimulation channel
• A 45-inch cable length
• A two-wire replacement package

Do not order solely by cable length or electrode-pin size. Confirm the device-side connection before purchasing.
