Stewart Connector Introduces SealJackTM Vertical Series-Ideal for Industrial and Field Applications

Glen Rock, PA, [May 11, 2017] Stewart Connector, a Bel group company, (NASDAQ: BELFA and BELFB) and world class supplier of RJ45 connectors used in Ethernet communications announces the SealJack™ Vertical Series product line for harsh environment RJ45 connector applications. The Vertical Series is ideally suited in support of connectivity for devices within the Internet of Things, where reliability and functionality are necessary when Ethernet moves outside typical office applications.

The SealJack™ Vertical Series is the first to launch in this new product line from Stewart Connector. The Vertical Series offers a uniquely sealed, light and compact design that can transmit 10/100 Base-T through 10G Base-T Ethernet. Configurations are available in 1 and 4 port vertical harmonica style designs with sealed protection rated for IP67 applications. The design allows for a front or rear panel mounting, and includes various LED options. These sealed connectors excel when electronics need to be protected from environmental conditions beyond what is capable using traditional RJ45 connectivity.
