The TE Connectivity CT series 292254-3 is a 3-position inline adapter with a plug on both ends — designed to join two male-header pin sets or to repair a broken wire-to-board run without re-terminating. Three circuits in a single row, panel-mount snap-in retention: it locks into a panel cutout for a fixed pass-through or a serviceable inline splice.
Three positions at this pitch keep the overall length under 10 mm, which fits inside a small junction box or behind a panel without crowding adjacent connectors.
