Neuroplex Inc. Offers a Sixteen Channel Multi Channel Preamplifier/Follower Head Stage with Unity Gain Preamplifier and Cables

 

HB04-BW  --Head Stage Plug with Unity-gain Preamplifier Array with Bare Wire

This unit consists of a small one cm square PCB with 16 high impedance preamplifiers to allow voltage sensing from two arrays embedded in parallel in mounting dental acrylic.  The preamplifiers are of excellent quality and yield minimal noise.  The signals from the follower preamps and the connections to system ground are led from the head stage plug with a group of low-noise 34-gauge connector wire, (24 inch standard length) to a DB-25 connector. 

 

 HB04-SSS  -- Head Stage Plug/Unity Gain Preamplifier Array with Spring Steel Shield.  

This unit consists of a small one cm square PCB with 16 high impedance CMOS precision preamplifiers to allow voltage sensing from two arrays embedded in parallel in mounting dental acrylic.  The signals from the follower preamps and the connections to system ground are led from the head stage plug with 34-gauge low-noise connector wire, (24 inch standard length) to a DB-25 connector.   A spring steel shield is included to protect the 16 wires from rodent bite.  The stiffness of the shield allows torsion to be applied to assist in turning a commutator or to activate a sensor with motor assist. Properly installed these units record from rats for 24 hours

 

Special  Order  Items -  HB04-BW/SSS-xx  --

Head stage Plug and Preamplifier Array  -    ‘XX’  specifies the length of the lead wire in inches. Long lead wires held from above may allow study of neural activity without need of a commutator for shorter duration recordings in some cases.

 

The DB25 plug connectors are wired to connecteed with the PA01 and PA02 preamplifier modules.  Connector wiring configurations can be specified to allow units to work with preamplifiers from other manufacturers.
