DC 2.35mm Ag/AgCl EEG Ear Clip Reference Electrode Cable

Black Ag/AgCl ear clip electrode with a DC 2.35mm safety male plug, developed for device-specific EEG reference connections and custom biosignal acquisition systems.

EEG Electrodes Ear Clip Electrodes EEG Accessories

The Heymed Medical DC 2.35mm Ag/AgCl EEG Ear Clip Reference Electrode Cable is intended for compatible EEG acquisition systems that use an ear-contact electrode as a reference input.

The assembly combines a black ear clip with an Ag/AgCl contact and a DC 2.35mm safety male plug. Its wiring and contact arrangement must be matched to the intended amplifier; plug appearance alone does not establish compatibility.

For OEM projects, Heymed Medical can review connector wiring, electrode contact details, cable length and lead construction, then develop samples around the customer’s approved interface specification.

Solutions & Applications

Device-Matched Ag/AgCl Ear Reference Connectivity for EEG Acquisition

The DC 2.35mm Ag/AgCl Ear Reference Electrode Cable is proposed for compatible EEG reference-signal acquisition. Its role is to provide an ear-contact signal path; it is not a stimulation controller or an independently operating medical device.
For OEM projects, Ag/AgCl contact construction, plug mating dimensions, pin assignment, cable length and optional shielding are evaluated together with the host EEG input. The same DC 2.35mm plug shape may be wired differently between devices.
Heymed Medical provides interface review, sample preparation, continuity verification and controlled cable assembly manufacturing, with documentation supplied according to the agreed project scope.

DC 2.35mm Ag/AgCl EEG Ear Clip Reference Electrode Cable

The DC 2.35mm Ag/AgCl EEG Ear Clip Reference Electrode Cable is designed for compatible EEG acquisition systems that use an ear-contact electrode as a reference input. It combines a black ear clip with a silver/silver chloride (Ag/AgCl) contact and a DC 2.35mm safety male plug.

This passive electrode cable provides an electrical connection between the ear-contact electrode and the EEG recording equipment. The connector wiring, electrode contact configuration and cable construction can be customized to match the intended acquisition system.

Ag/AgCl Ear Clip for EEG Reference Signal Acquisition

In an EEG recording system, an ear electrode may be used as a reference contact according to the amplifier design and selected electrode configuration.

The black ear clip incorporates an Ag/AgCl contact intended for integration into compatible EEG reference-signal applications. Contact dimensions, electrode placement and connection requirements should be verified with the finished device.

This product is designed for passive biosignal acquisition and should not be treated as an interchangeable replacement for a taVNS stimulation electrode.

DC 2.35mm Safety Connector for Device-Specific EEG Interfaces

The device-side connection uses a DC 2.35mm safety male plug. Its compact design provides a connection option for EEG equipment equipped with a matching interface.

Electrical compatibility depends on the actual connector dimensions, pin assignment and EEG amplifier input. The same DC 2.35mm connector shape may use different wiring configurations across equipment designs.

For systems requiring additional recording electrodes or customized electrode arrangements, our EEG & EMG Electrodes & Cables range provides related electrode and lead-wire solutions.

Designed Around the Complete EEG Recording System

An EEG reference electrode must work with the recording electrodes, amplifier input and system wiring. Contact placement, cable routing and reference-channel configuration should therefore be considered together during equipment development.

For multi-channel EEG projects, the ear-reference cable may be evaluated alongside compatible recording accessories such as the 32-Channel EEG Electrode Cap with 10–20 Electrode Positioning. The final reference connection and channel arrangement must follow the approved EEG system design.

Custom EEG Ear Reference Electrode Cable Options

Electrode contact: Ag/AgCl contact structure and dimensions according to project requirements.

Device connector: DC 2.35mm safety male plug with approved wiring configuration.

Cable configuration: Customized length, conductor structure, jacket material and optional shielding.

Frequently Asked Questions (FAQ)

Resolve your concerns in advance — stress-free communication, efficient coordination

Q1

What is a DC 2.35mm Ag/AgCl EEG ear clip reference electrode cable?

It is a passive ear-contact cable assembly intended to connect a compatible EEG reference input to an Ag/AgCl ear clip electrode through a DC 2.35mm safety male plug.

Q2

Does a DC 2.35mm plug make this electrode compatible with every EEG amplifier?

No. The mating connector, pin assignment, polarity or signal wiring, electrode contact configuration and EEG input requirements must be verified for each target device.

Q3

What electrode contact material does the black ear clip use?

The supplied product description specifies a silver/silver chloride (Ag/AgCl) ear clip contact. The exact contact dimensions and construction should be confirmed against the production sample and approved drawing.

Q4

Can the connector wiring and cable length be customized?

Yes. Connector wiring, cable length, conductor construction, lead identification and optional shielding can be reviewed and developed according to approved OEM/ODM requirements.

Q5

Is this EEG reference electrode the same as a taVNS ear stimulation electrode?

Not necessarily. Both products may use an ear clip, but EEG reference acquisition and auricular stimulation have different electrical roles. This product should be specified and validated for its intended EEG system rather than described as universally interchangeable.

Q6

What information should a buyer provide for a custom EEG ear electrode project?

Please provide the EEG device model, reference-input definition, DC 2.35mm mating drawing, pinout, desired cable length, contact requirements, sample or photos and expected quantity for engineering review.
