What This Seal Does
The TE Connectivity 2108883-1 is a seal accessory designed specifically for use with USB - microUSB B connectors. It fits over the connector interface to protect the mating point from moisture, dust, and debris — a common requirement when a standard microUSB B port is deployed in an enclosure that sees occasional splashes or particulate exposure. The seal is supplied in a Bag package, making it straightforward to kit alongside the connector for assembly.
This seal mates with USB - microUSB B connectors. If you are building a panel-mount or cable-mounted microUSB B connection that needs an IP-rated seal, this is the part that goes over the connector body. No other connector types are listed as compatible.
