View model pageGeneral guidance
In general, a terminal bushing is an insulating bushing that carries an electrical connection through a housing or panel while keeping it isolated from the surrounding metal. In heavy equipment, such parts are used in electrical circuits and switch or sensor assemblies where a conductor must pass through a barrier.
Use part number 0128140 exactly as listed when identifying this catalog item. Before ordering, check the machine's model, serial number and configuration against the catalog associations shown, since a listing does not establish compatibility for every machine configuration.
