The sealed designation indicates the housing accepts a peripheral seal (gasket or O-ring, not included) when mated with the corresponding receptacle, giving the assembly an IP rating for splash or dust resistance in damp environments. Together, these two features let you run this connector inside an appliance enclosure without a secondary potting step. The series accepts TE's SDL 2.5 crimp terminals (typically 20-24 AWG, tin or gold plated depending on the application). When sourcing this housing for a harness build, add the correct terminal part number to the BOM to avoid a line-down situation. The latch holder and the housing geometry are designed to work only with the SDL 2.5 contact family.","metaTitle":"TE Connectivity 2321918-4 SDL 2.5 Plug Housing, 4 Pos","metaDescription":"TE Connectivity 2321918-4 SDL 2.5 plug housing, 4-position, 2.50mm pitch, glow wire compliant, sealed.
