Connector, gland, and grip options for industrial- automation cabling There are various connectors to join cables and components used in industrial automation. These connectors must transmit all power and data-signal streams carried over the cables while terminating the line in a way that keeps the conductors tightly connected and protected. The challenge is that equipment associated with industrial automation is often located in dirty, hot, mobile, and electrically noisy settings … so industrial cable connectors require a level of robustness and reliability not necessary for other applications. First, consider some industrial- connector basics: Connectors include the components classified as couplers (which join two cables) as well as systems that include both the plug and socket (or receptacle) halves of a connector assembly. In some contexts, the term connectors can also refer to cable glands — terminations that pass through enclosures … often with a free- spinning subcomponent that acts to compress an O-ring seal around the cable end to close it off from chemicals, flames, dirt, and extraneous currents.
