The 34923T connection block is intended for the Keysight 40/80 channel reed multiplexer 34923A (formerly Agilents electronic measurement technology). The block is designed for discrete wiring to connect wires with up to 20 AWG for approx. <100 connection changes or 24 AWG for> 100 connection changes.
The block can be attached to the multiplexer and secured with screws. It is therefore a flexible and simple method to do the wiring yourself.
