ExG Sensor cable

The universal bipolar NeXus ExG Sensor uses special shielding technology and is designed for measuring 1 or 2 Biopotential (ExG) channels such as EEG (brain activity), sEMG (muscle activity), ECG/EKG (heart rate and HRV) or EOG for eye movement. (Electrooculography). Because it is a dual channel bipolar cable, it has two red snap-on connectors (positive) and two black (negative) snap-on connectors which are compatible with most ECG/EKG/EMG self-adhesive electrodes and our blue disc EEG electrodes.

 

The other version of this ExG cable has standard 1.5 mm TP (touch proof) EEG connectors and is only used for EEG applications that require bipolar connections.  Please note that we also have linked-ear (LE) cables for EEG, which have up to 4 (uni-polar) red (positive) electrodes but the black (negative) electrodes are all shorted and connected (referenced) to the (linked) earlobes or mastoids.  You can find that cable under the other sensor section called "EEG Linked Ear Sensors".

 

Features

The ExG Sensor is provided with easy snap-on connectors for using various types of electrodes. NeXus sensors are supplied with shielded cables and brushed metal medical grade ODU connectors. This cable in combination with the active noise cancelation of the NeXus systems reduce 50/60 Hz noise and movement artifacts. Measuring electrophysiological signals always requires a ground reference cable.

The ExG Sensor for NeXus offers:

• 1 or 2 channels of bipolar EEG, EMG, ECG or EOG
• Combine 2 sensors for measuring up to 4 channels of EEG or EMG
• Snap-on leads for various types of electrodes
• Shielded cables for a minimum of noise and movement-artifacts

Systems

The EXG Sensor is available in 2 types.

NeXus: for the NeXus-10 (MKI, MKII), NeXus-4, NeXus 32F. This sensor comes with an ODU Aluminium connector. Regular NeXus EXG is a Snap-On connector for which electrodes can be snapped on. For the NeXus it also available with a TP/DIN connector that requires a TP/DIN to Snap-On cable.

Q32: for the NeXus-Q32. This sensor comes with a black plastic ODU connector, only available as a Snap-On.
