Delphi Weather Pack Connectors are environmentally sealed electrical connections designed to withstand exposure to extreme temperatures and moisture. Terminals are tin plated and have special core wings which allow crimp-only connections, eliminating the need for solder. The connector and cavity seals are triple-ribbed and made of self-lubricating silicone. Cavity plugs are available to fill unused cavities. Some of the benefits include; Sealed system specifically designed to withstand exposure to extreme temperatures, chemicals and fluids; Pin and sleeve configuration to alleviate stress relaxation; Secondary lock and Connector Position Assurance (CPA) for improved system design; Dual-locking tangs on terminals help prevent backing out; Terminal plugging requires no orientation; Positive locking indexing prevents mismating of connectors; Low energy & low voltage capability for vehicle electronics. Weather Pack proven harsh environmentally sealed components can be utilized in both in-line and panel-mount applications. They are ideally suited for use in harsh environments where resistance to temperature extremes, chemicals and fluids are a must like with commercial vehicle and marine applications.
