Solutions for making machines run leaner, smarter and cheaper come in all shapes and sizes, and connection products can play a significant role in this endeavor.
"Everybody wants to reduce cost, and cabling's a big part of that," notes Robert Muehlfellner, director, automation technologies, for B&R Automation.
Muehlfellner sees a trend within machinery that calls for more modularization as end users demand more options and more customization. "Along with this, there are trends toward decentralization of the electrical components, and more machine-mount I/Os and drives," he says. "Intelligent connection and cabling technology plays a more prominent role than it did in the past."
Passive distribution blocks are also resurging, according to Aaron Henry, marketing manager at Murrelektronik . They are similar to machine-mount I/O devices, he explains, because they refrain from active communications and have simple, homerun wiring to I/O cabinets. "Many machine builders in U.S. markets are constructing progressively smaller machines with smaller I/O counts, but they still want to build them faster, and so they're using more passive distribution blocks," he says. "These allow easier troubleshooting and reduce wiring without having to justify and implement a full-blown fieldbus."

SmartWire-DT panel wiring system connects motor control components with a single cable over EtherNet/IP, Modbus TCP, Profibus-DP and CANopen. It uses an eight-conductor, flat cable in the control cabinet to connect motor starters, pushbutton actuators and indicator lights.
|Socket to Me
756 Series M12 socket Ethernet adapter helps integrate machine-mount IP67 components with IP20 controls. Tool-free terminations with D-Coded M12 Adapter have a traditional cable-based RJ45 Ethernet socket that routes data through a screw-locking M12 connector.
|Patch It Up
Industrial Ethernet RJ45 patch cables are available for EtherCAT, SERCOS III and Profinet protocols in 0.3, 1 and 2 m lengths. Options include straight or angled configurations that meet IP20 protection requirements.
|Time to Split
G10 AS-Interface accessories include IP69K washdown-rated splitters and network terminators that feature Connect & Done technology to eliminate mounting requirements in many applications and simplify mounting in others. Standard flat cable connection for both AS-Interface and auxiliary power includes two M12 round cable connections, so two devices can be split off from one accessory.
EKI-1221D and EKI-1222D gateways provide transparent connectivity between Modbus (ASCII, RTU) serial devices and Ethernet-based Modbus TCP equipment. They have built-in Ethernet switches for cascading/daisy-chain connectivity and support Ethernet auto-bypass to prevent accidental power failure if one of the Modbus gateways unexpectedly shuts down. They come with Windows utilities and web-based configuration.
Advantech Industrial Automation
Cat. 5e straight and crossover Ethernet patch cables in eight colors and 3-50 ft lengths support up to 1,000 Mbps and are designed to reduce the effects of electromagnetic interference by using one metal-foil shield that wraps around the set of four twisted, shielded pairs and shielded RJ45 connectors. The 350 MHz cables exceed all Cat. 5e TIA/EIA standards, and reduce impedance and structural return loss (SRL) compared with standard 100 MHz cables.
