Medical Electrode Lead Wires | 2.0mm Pin & 3.5mm Snap | TOP-RANK
Industrial-grade TENS/EMS lead wires for clinical stimulators. Features high-flex copper cores, TPU/PVC insulation, and reinforced strain relief. Compatible with standard electrode pads.
Product Overview
hese are the primary electrical transmission lines between the pulse generator (TENS/EMS/IF) and the electrode interface. The design focuses on minimizing signal impedance and preventing mechanical failure at the junction points. We supply these as secondary consumables for B2B clinical distributors and device OEMs.
Key Features
Fatigue-Resistant Strain Relief
Cables typically fail at the point where the wire enters the plug. We use an extended, tapered strain relief sleeve that distributes mechanical stress over a 30mm area. This prevents internal copper fracture during repeated clinical handling.
Low-Impedance Copper Core
Signal attenuation occurs if the copper purity is low. We use a high-strand-count conductor (typically 28AWG to 24AWG) to maintain a resistance of less than 0.5 Ohms per meter. This ensures the stimulator's pulse reaches the electrode without significant voltage drop.
Disinfectant-Ready Insulation
Clinical environments require frequent wiping with isopropyl alcohol or bleach solutions. Our TPU insulation is formulated to resist polymer degradation and "stiffening" caused by chemical exposure, maintaining cable flexibility over 12+ months of use.
Applications
- Physical Therapy Clinics: High-frequency daily use with TENS and EMS machines.
- Home-Care Devices: Durable replacement wires for consumer-grade stimulators.
- OEM Device Bundling: Factory-original cabling for new electrical stimulation units.
OEM & Private Label
We operate dual-hub manufacturing in China and Vietnam to provide supply chain redundancy and Section 301 tariff mitigation.
- Custom Connectors: Tooling available for proprietary 4-pin, 6-pin, or USB-style stimulator inputs.
- Branding: Injection-molded logos on the plug housing or custom-printed heat-shrink labels.
Certifications
- Regulatory: CE (MDR), FDA 510(k) for associated systems, and UKCA.
- Systems: ISO 13485 and MDSAP.
- QC Testing: Every batch is tested for continuity, dielectric strength (high-pot test), and pull-force resistance at the connector-wire interface.
FAQ
Q: Why do the wires develop "crackling" noise after 6 months?
A: This is usually a sign of internal micro-fractures in the copper strands. Even if the insulation is intact, the core eventually fails from repetitive bending. We use high-strand-count wire to delay this fatigue limit.
Q: Can these cables be autoclaved?
A: No. These are PVC/TPU based and will melt or degrade in high-pressure steam. They are designed for surface disinfection only.
