206251-1 is a coupling ring accessory designed for circular plastic connectors (CPC) with shell size 23. The coupling ring is manufactured from polyphenylene oxide (OPC), a durable engineering polymer that provides excellent mechanical strength and chemical resistance. This component is used to secure and align connector shells in circular industrial connector assemblies, ensuring reliable mating and demating cycles. The product is EU RoHS compliant, meeting environmental and safety standards for industrial applications. Coupling rings are essential components in modular connector systems, particularly in applications requiring frequent connection/disconnection or demanding environmental conditions.
