SDL Series Boot Plug for Round Cable
The TE Connectivity 520853-1 is a boot plug accessory for the SDL connector family, designed to fit an 8-position round cable. It is the protective overmold shell that goes over the plug housing after the contacts are terminated — not a connector itself, but the piece that gives the mated pair its strain relief and environmental seal at the cable exit.
What It Fits and Where It Goes
This boot is specified for use with SDL connectors, TE's subminiature D-style rectangular interconnect used in high-density signal applications. The 8-position variant matches the 8-circuit SDL plug housing. On the assembly line, the boot slides over the terminated plug and is typically potted or bonded to seal the cable entry against moisture and strain.
