Plexon offers a wide variety of headstage cables to connect any Plexon headstage to its compatible amplifier/processor. We offer a choice in wire size to more closely match your needs. Additionally, several specialized cable wraps are available and can be applied to protect your investment from animal bites or other damage. Plexon is committed to the success of your research and is happy to manufacture the cables – wire, lengths, connectors, wraps and configurations – to meet your needs.
Headstage cables are available in a variety of options including: wire gauge, cable wraps, lengths, connectors and configurations. The proper build will improve the quality of your recordings as well as protect your investment. All Plexon headstage cables are reusable.
Standard 34 gauge
The standard gauge for headstage cable wire used by Plexon is 34 gauge which is flexible, yet robust. 34 gauge wire is ideal for head-fixed experiments, or for research in which the freely behaving animals are unlikely to be impeded by the cable. The standard 34 gauge wire is easy to identify as the wire insulation is multi-colored.
Ultra-fine 36 gauge
If your experiments require small animals such as mice, we recommend our 36 gauge ultra-fine wire. This thinner cable wire is lighter-weight and is less likely to impede the behavior of smaller animals. Additionally, digital headstages exclusively use 36 gauge wire. The ultra-thin wire is also easy to identify as it has white wire insulation.
Unless otherwise requested, headstage cable wires are bound using tiny shrink-wrap cuffs spaced approximately every 1.0 to 1.5 inches (shown in the images above). There are situations, however, in which the standard cuffed method may not be sufficient: if the cables may be snagged during normal use, damaged by biting animals, or if you wish to increase the cable torque transmitted to a standard, non-motorized commutator for more effective operation. In these circumstances, we recommend one of the following wraps. The wraps are presented in order of increasing strength, weight and protective qualities. All wraps are available for all cables.
Polyester Mesh Wrap
polyester mesh wrap is the lightest-weight and most flexible wrap Plexon offers. It will protect the headstage cable from damage incurred due to general use such as snagging, and is light enough and flexible enough for use with small animals, such as mice. This wrap is recommended for use on ultra-fine 36 gauge wire cables, and if working with small animals.
Clear Plastic Wrap
The next step up in strength is the clear plastic wrap. It provides some additional benefit over the polyester mesh wrap with respect to protection from damage incurred during standard use, and is slightly stiffer. The clear plastic wrap is especially beneficial if your experimental set-up includes a non-motorized, Standard Commutator. A plastic-wrapped headstage cable will transmit torque to the commutator better than an unwrapped or polyester mesh-wrapped headstage cable will.
