The TE Connectivity 552116-1 is a 50-position plug from the CHAMP.085 series, built as a through-hole solder-mount connector with center strip contacts. The board-side flange gives the panel-mount stability when the mating half is screwed in, so the connector stays seated against vibration. This is the board-mounted male half of the CHAMP.085 pair; it mates with the corresponding CHAMP.085 receptacle (cable or panel side) to form a dense I/O interconnect for telecom, data, or industrial control backplanes.
50 Positions, 2 Rows — the BOM Line Match
At 50 circuits in a 2-row layout, this plug matches the standard density of the CHAMP.085 family. The position count is the first check against the bill of materials — if the mating receptacle or the cable assembly calls for 50 contacts, this is the board-side plug to pair. The through-hole solder termination keeps the connection mechanically solid for backplane or I/O card mounting where rework is rare.
