Omnetics Based Microwire Arrays

Standard 50 um polyimide-insulated tungsten microwire gives the arrays excellent recording characteristics and the rigidity of tungsten facilitates insertion. The standard OMN1010 array consists of sixteen channels configured in two rows of eight electrodes each and are typically accessed via our RA16CH 16-channel headstages. OMN1005, OMN1020, and OMN1030 share this standard configuration with varying electrode separation specifications. Consult the documentation provided with your array for custom specifications.


This section provides information specific to TDT arrays. For more general information see Suggestions for Microwire Insertion.

Grounding the Electrode

Our latest laser cut microwire arrays (OMN1010) have one location each to connect needed ground and reference wires. Because the reference and ground are shorted together in our RA16CH chronic headstages (unless the jumper is cut by the user) only one wire will be needed for most cases.


The solder pad is located on the backside of the microwire circuit board.

The illustrations above show a single wire connected to the ground pad located on the backside of the array.


The microwire array can be damaged by extreme heat. Use caution when soldering.
