Adapters
We have a wide array of adapters for all commonly used electrodes and connectors; too many to list here. If you need a custom connection, our engineering teams are no strangers to modification, alteration, or customization. Contact sales@rppl.com for inquiries.
Touchproof Adapter
- Useful for applications that require the use of 1.5 mm safety DIN connectors, such as surface EEG, ECoG, and EMG electrodes
- The Touchproof Adapter prevents unwanted environmental noise pick up, through switches that ground unused channels
- Versions are available for use with all single-ended and differential Front Ends
Specifications
- Electrode Connector: 1.5 mm male 60601-compliant touchproof
- Dimensions: 105 mm x 64 mm x 26 mm
- Weight: 170 grams
Screw-Terminal Adapter
- Useful for single-wire electrode applications with either single-ended or differential Front Ends, including terminals for grounds and references
- The Screw Terminal Adapter prevents unwanted environmental noise pickup via individual switches that ground unused channels
Specifications
- Dimensions: 90 mm x 75 mm or 22m x 25 mm
Utah Array Pedestal Connector

- Connect up to four nano or pico front ends for up to 128 channels of recording and stimulation
- Removeable enclosure allows for easy access to the front ends while providing protection from damage
Specifications
- Dimensions: 15mm X 26mm X 26mm (44mm tall with enclosure)
- Weight 8.4 grams (15.7 grams with enclosure)
