Product Overview

The Keysight 34925T is a terminal block for the 34925A 40/80-channel FET multiplexer, used for discrete wiring. It supports up to 20 AWG wire size for up to 100 connections or 24 AWG for 100 connections or more. Two terminal block options facilitate wiring connections to the 34925A module:

34925T-001 (Option 001) Terminal Block for 2-wire configurations
34925T-002 (Option 002) Terminal Block for 1-wire configurations

The 34925T is a detachable terminal block that provides a flexible method for connecting external wiring.
