Stewart Connector, a division of Bel Fuse Inc., (NASDAQ: BELFA; BELFB) has released a new large-diameter Category 6a 8P8C modular plug (SS-39200-027). The new RJ45 plugs are the latest addition to Stewart Connector's range of connectors designed to support Gigabit Ethernet (1000Base-T) and 10 Gigabit Ethernet (10GBase-T) transfer rates, along with PoE (Power over Ethernet). They notably accept a cable diameter range of AWG23 to AWG24 and accommodate conductor sizes up to 0.048" in diameter.

The UL Listed, RoHS-compliant connectors are specifically offered to support terminations requiring horizontal cabling, which extends from the telecommunications outlet in the work area to the horizontal cross-connect in the telecommunications room. Horizontal cabling is often specified in direct connect or consolidation point applications where link lengths exceed 10 meters (33 feet). Since the cabling used in these systems is typically made of AWG23 or AWG24 solid conductor copper and is larger than traditional patch cable, standard modular plugs cannot be used. Due to Stewart's proprietary contact design and unique conductor load bar, the SS-39200-027 large diameter plug is able to terminate the large diameter horizontal cabling in the same form factor as traditional RJ45 modular plugs.

Stewart Connector says the new low-profile, large diameter, modular plugs are well suited for high-density switches and routers, and can be used in both shielded and unshielded applications. They feature a snag-less strain relief boot to prevent plug tab damage during installation and a wire aligner to ensure precise conductor placement during assembly. Moreover, the Cat 6a connectors incorporate 360-degrees of shielding to protect signals from external noise.

The unit's plug, load bar and wire aligner are manufactured of UL94-V0 polycarbonate and feature 50 microinches gold-plated contacts for robust, long-lasting connections. Additional specifications include an operating temperature range of -40 degrees C to +85 degrees C, and durability of 750 matching cycles. Voltage rating is 150 VAC, and current rating is 1.5 A @ 25 degrees C. Parts are field installable with standard Stewart Connector's termination tooling. Plug kits are offered individually bagged in packaging suited for field installation as well as bulk packaged for factory terminations.
