5-Prong Ag/AgCl-Coated ABS Dry EEG Electrode for Brain Monitoring
This 5-prong dry EEG electrode features five rounded contact posts arranged on a compact circular base. The ABS-based structure uses a silver/silver chloride (Ag/AgCl) surface-treatment specification for integration into compatible EEG recording systems, wearable brain-monitoring devices and neuroscience research equipment.
Unlike a densely packed metal comb electrode, this design uses five larger contact prongs. It offers an alternative scalp-contact geometry for equipment developers who need to consider hair clearance, electrode positioning and mounting space. Heymed Medical supports OEM/ODM development based on the intended electrode holder and biosignal acquisition system.
Five Contact Prongs for Scalp EEG Acquisition
The five-prong structure is designed to help establish multiple contact points within a single scalp-electrode assembly. Its rounded contact ends can be evaluated for EEG caps and headsets where hair and mounting pressure affect the electrode-to-scalp interface.
All five prongs form part of one electrode structure rather than five independent recording channels. Actual contact quality depends on the electrode material, fit, applied pressure and the recording system.
For projects requiring a denser metallic contact array, the 24-Pin Ag/AgCl Comb Dry EEG Electrode provides a different scalp-contact design with a 3.9mm snap interface.
ABS Construction with Ag/AgCl Surface Treatment
The reference electrode uses an ABS-based body with a specified silver/silver chloride surface treatment. This construction is different from solid-metal or powder-sintered Ag/AgCl electrodes and should be selected according to the intended electrical and mechanical requirements.
Contact coating, prong dimensions, surface condition and mechanical durability are important during sample evaluation. Electrode impedance and signal quality should be checked under the actual wearing and recording conditions rather than assumed from the material name alone.
Integration into EEG Caps and Headset Holders
The circular base is intended to be evaluated with a suitable electrode holder or headset mounting structure. The reference design includes features on the underside and side of the base, but the final mating dimensions and electrical connection method must be confirmed from the actual sample or drawing.
For EEG equipment development, electrode positioning, holder fit, cable routing and connection to the acquisition electronics should be reviewed together. This helps ensure that the electrode remains correctly positioned during the intended measurement procedure.
Other dry electrodes, EEG accessories and compatible biosignal lead wires are available through our EEG & EMG Electrodes & Cables range.

From Electrode Sample to Production
Heymed Medical works with EEG device developers and equipment manufacturers to review electrode geometry, material specifications and matching installation requirements.
Customers can provide an electrode drawing, reference sample, headset holder dimensions or electrical requirements for engineering evaluation. Samples can then be checked for mechanical fit, contact condition and compatibility with the intended acquisition system.
For custom electrode connections, matching lead wires and related development, our Medical Cable OEM/ODM Customization service supports product engineering and sample preparation.
Technical Information for Quotation
Please provide the required electrode dimensions, contact coating specification, mounting method, matching interface and estimated order quantity. Final material performance, patient-contact safety and regulatory requirements should be verified for the completed device.
