What is Y-connector?

A type of adapter that can be used to connect a single device or cable to two devices or cables. Examples of Y-connectors include the following:

  • RJ-11 Y-connector: Allows two or more telephone devices to be plugged into a single RJ-11 wall plate. Some vendors call these adapters modular coupler splitters. This arrangement allows only one of the devices to work at any given time. 
  • SCSI Y-connector: Allows a Small Computer Systems Interface (SCSI) device to be added to the middle of a chain of SCSI devices. A typical SCSI Y-connector has one 50-pin Centronics male connector and two 50-pin Centronics female connectors. One use for a SCSI Y-connector is the connection of a single RAID-5 SCSI array to two nodes of a cluster when Microsoft Cluster Server (MSCS), which is included in Microsoft Windows NT Server 4, Enterprise Edition, is used.
