Description
The 155411A-02L TB-4339B is a front mount terminal block designed for use with the PXIe-4330/4331 Universal Bridge Input Modules, featuring a 350-ohm 1/4 bridge and a 100k-ohm shunt calibration. This accessory ensures secure and simple installation with integrated mechanical interlock system and captive screws, promoting signal quality and compatibility with the host module.
The 155411A-02L TB-4339B is a front mount terminal block designed for use with the PXIe-4330/4331 Universal Bridge Input Modules. Specifically created as a variant of the TB-4339, this accessory features a 350-ohm 1/4 bridge and a 100k-ohm shunt calibration NI TB-4339B Terminal Block. With an integrated mechanical interlock system, the TB-4339B ensures that it can only be used with the compatible host module and cannot be accidentally coupled with an incompatible one. The captive screws securely hold the module with the chassis, allowing for easy installation and removal without shutting down the PXIe based acquisition system. Despite its low trace resistance, this terminal block maintains signal quality as it leaves the accessory through the main connector. Remember, the part specifically referred to is named 155411A-02L.
