The TE Connectivity 207446-3 is a sealing cap for the CPC (Circular Plastic Connector) series, specifically a shell size 23 cover that protects unmated receptacle connectors from dust, moisture, and physical damage. It is molded from black thermoplastic and includes an integral strap with a ring, allowing the cap to be tethered to the cable or panel so it stays with the assembly when the connector is unmated. This accessory is designed for use with CPC Receptacle Series 1, 3 and 4 — the three most common circular plastic receptacle families in the TE lineup.
Shell Size and Fit
The shell size 23 is the critical dimension — it matches the outer diameter of the corresponding CPC receptacle housing. When you order a CPC receptacle, the shell size is part of the mating interface; this cap fits only shell size 23 receptacles, not smaller or larger sizes in the same series. The cap snaps over the receptacle face and the strap with ring provides a retention point so the cap doesn't wander off during field service.
Compatibility with CPC Receptacles
This sealing cover is compatible with TE CPC Receptacle Series 1, 3 and 4 — the three main circular plastic receptacle families. Series 1 is the standard industrial-duty line, Series 3 adds environmental sealing, and Series 4 is the high-density variant. All three share the same shell size 23 outer profile, so one cap covers all three families at that shell size.
Construction and Features
The cap is molded from thermoplastic, giving it good impact resistance and dimensional stability across the typical industrial temperature range. The strap with ring is molded as part of the cap — not a separate add-on — so it won't separate in the field. Bulk packaging means the caps ship loose, suitable for kitting or panel-line distribution.
