Dust cover for MTA-100 harnesses
The 640550-7 is the 7-position closed-end dust cap in TE Connectivity's MTA-100 connector accessory line, designed to protect unmated MTA-100 series headers and receptacles from debris and handling damage on the harness floor.
Position count across the cap family
The 640550-7 covers 7 circuits and sits between the 6-position 640550-6 and the 8-position 640550-8 within the same closed-end MTA-100 dust cap series — all share the same Bulk packaging, closed-end feature, and MTA-100 compatibility, so the selection axis is simply matching the cap to the header position count. A 9-position cap (640550-9) is also available for larger harness assemblies.
