Connectors and toothbrushes have something in common. Everybody uses them. In the industrial market, connectors are used in anything from programmable controllers to robotics in a variety of industrial segments from automotive manufacturing to consumer electronics. All of these industries are large because of the scope of their missions. A recent report from Electronics.ca Publications indicates that, by 2010, the industrial market for connectors will reach $6 billion.

Because of the industrial environment, many of the connectors are robust. Examples include the use of stainless steel connectors in equipment that processes caustic chemicals. Stainless steel also finds applications in the manufacture of sanitary food processing equipment. Other manufacturers will choose materials that match their environments. Often, the connectors used in the industrial environment were designed for another purpose. In some instances, industry uses military-style connectors or converters developed for the medical industry.

A key focus in today’s market is connectors for industrial Ethernet applications. As manufacturing of standard connectors shifts to China, Asia and India, the U.S. might have a better chance of dominating the market with industrial Ethernet connectors.

Ethernet typically uses RJ-45 connectors. These were great when they sat in the office environment, but as they have moved to the factory floor, many suppliers have made the connectors more robust; equipped them to withstand dirt, vibration, corrosives and other nasty conditions; and also made mounting more stable. Ethernet-enabled components also ease the ongoing controversy between the IT department and manufacturing. They are open and flexible enough to grow with present and future networks and add Internet, wireless and other settings. As standards are developed for these Ethernet products, implementation will become more common and save wiring and cable costs.

TOOL-FREE ETHERNET CONNECTIVITY
Eight-pole 750-975 pluggable RJ-45 Ethernet connector decreases the time needed for wiring. The connector has insulation displacement contact that provides tool-free, in-the-field conductor wiring—simply insert a pre-stripped conductor and lower the locking mechanism. It is suited for applications in close proximity to machines, such as those in suspended ceilings or distribution boxes because there is no need for crimp tools or preparation of the conductor ends.

SIMPLIFIED CONNECTIONS
Family of adapters simplifies and speeds the connection of intelligent sensors, emergency stop switches and modules to AS-Interface and is intended as a wiring solution for machines built, tested and broken down for shipment before being reassembled at the customer’s plant. AS-Interface flat-to-M12 adapter cables are available in straight or 90° M12 head angles with single or dual-flat-cable configurations in lengths of 0.3 m, 1 m, 2 m or 5m.

SMALL CONNECTORS
Three and four-pin M16 powerfast connectors handle 15 A of current for conveyor, small motor and material handling applications. The cordsets are available with a tray-rated, exposed run PVC flexlife cable. All connectors provide IP67 protection and are rated for 600 Vac/Vdc. M16 powerfast cordsets offer male and female, straight connectors, standard and custom lengths and pigtails or extensions. Fully encapsulated mating receptacles with nickel-plated brass housing and ½-14 NPT, 3/8-18 NPT, M18 and M20 mounting threads complete the system.
