Module CX-25 for heavy-duty rectangular connectors is used in applications where high volumes of data or signals are transmitted in a small space. These modular inserts work with the MIXO Series frame which allow the end user to create a custom connector. These modules can be used individually in a single frame or combined with up to five other modules in the larger six-slot frame. The 25-pole insert helps round out a very extensive line of modular connectors.
