Sensor Cable - Electrode Pads (3 connector)

The Sensor Cable with 3-Connector Electrode Pads is an essential accessory for bio-signal measurement systems, providing the critical link between disposable electrode pads and your data acquisition or monitoring device. It is widely used in applications that require capturing bio-electrical signals from the human body, including ECG (electrocardiography), EEG (electroencephalography), and EMG (electromyography).

The cable terminates in three snap-style connectors that attach securely to standard pre-gelled electrode pads (commonly the Ag/AgCl gel-coated disposable type). On the device side, the cable typically uses a standard 3.5mm jack or board connector compatible with popular bio-signal modules such as the AD8232 single-lead ECG module, MyoWare muscle sensor, and other educational, fitness, and clinical bio-signal front-ends.

The cable is constructed with flexible, durable shielded wires to minimize movement artifacts and electrical interference — both of which are critical for obtaining clean, accurate biological signals. The conductors are color-coded (commonly red, yellow/black, and green/white) to match standard ECG lead placement (RA, LA, RL or LL), making it easy to follow medical and educational placement diagrams.

Combined with soft, skin-friendly electrode pads, the system provides comfortable, low-impedance contact with the skin, which is essential for capturing low-amplitude bio-electrical signals reliably. The disposable pad design ensures a fresh, hygienic contact surface for each session, which is important both for signal quality and skin comfort.

This setup is widely used in medical training, biomedical engineering courses, fitness wearables, sleep monitoring, telemedicine projects, and DIY health tech experiments with Arduino, Raspberry Pi, and ESP32 boards.

Note: This is a measurement and educational product — it is not intended as a certified medical diagnostic device. For clinical diagnosis, always use FDA / CE-approved medical equipment.
