Stewart Connector

Stewart Connector is the leading designer/manufacturer of high-quality, high-performance modular jacks and plugs for the telecommunications, local area network (LAN), data processing, medical instrumentation, automotive, and industrial markets. Headquartered in Glen Rock, Pennsylvania, Stewart was acquired by Bel Fuse Inc. in March 2003. Bel (www.belfuse.com) and its subsidiaries design, manufacture and market products used in networking, telecommunications, automotive and consumer electronics. Products include magnetics and connectors for voice and data transmission, fuses, DC/DC converters, power transformers, delay lines and hybrid circuits. Bel operates facilities around the world.
 
With more than 2,000 modular connector products, Stewart Connector thrives on new designs for leading edge customers. Stewart pioneered the development of shielded multiport jack systems that eliminate EMI/RFI noise while improving high-speed transmissions. We followed that with the CableJack™, a CAT 5e cable-ready jack for use in Gigabit Ethernet applications, the MICROJACK®, an ultra small form factor for PCMCIA cards, and the CompressorJack™, a low-profile, high-performance stacked jack used to maximize rack densities. Most recently, we released a CAT 6 modular plug that meets/exceeds proposed EIA/TIA requirements.
 

In 1996 Stewart developed and marketed modular connector products with integrated magnetics. Today the customer list for MagJacks™ includes the biggest names in communications and computing with tens of thousands of ports of product shipped each month. MagJack’s success is the combined result of innovative engineering, complete customer focus, a well-developed manufacturing capability, and competitive pricing.

Stewart modular jacks feature selectively plated drawn-wire contacts with low porosity plating for maximum durability. Unique electropolished mating surfaces and patented wire termination technology allows for unmatched plug durability and reliability. Stewart Quality begins with our solid engineering group and manufacturing expertise for modular connector systems. Stewart Connector is ISO 9001 approved.
