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."
Industrial-grade DataTuff Cat. 6 cord sets for Gigabit industrial Ethernet needs come with RJ45 plugs, available in shielded and unshielded versions suitable for IP20 or IP67 applications, or with ruggedized metal body RJ45, and handle -40 to 70 °C.
|Make a Remote Connection
8CVE remote connection box has IP65 protection, and comes with four hybrid cable outlets, allowing the power to be divided between up to four line structures of Acoposmulti65 8CVI inverters; and the connections necessary for Safe Torque Off (STO) signals are included. It has two local I/O connections.

Vlinx VESP211 small-form-factor serial servers connect serial devices to Ethernet networks. VESP211 supports RS-232/422/485 (MEI) with a DB9M serial port and RJ45 Ethernet port. VESP211-232 supports RS-232 with a DB9M serial port and RJ45 Ethernet port. VESP211-485 supports RS-422/485 with a removable terminal block and RJ45 Ethernet port.
EtherNet/IP Communications Auxiliary enables DeviceNet-based components to connect to an EtherNet/IP network. Users can access the status of any DeviceNet device in the network from a PC or PLC.
|From Serial to Ethernet
Available with one to 16 ports, SeaLink Ethernet serial servers connect RS-232, RS-422 and RS-485 serial devices to your Ethernet network and use TCP/IP, enabling any host to access serial ports as virtual COM ports.
|Connect With Professionals
Professional RJ45 connectors for either eight-pin Cat. 5e or four-pin Cat. 6A are available in straight and angled designs, and have a 45° angle for multiple connections in tight spaces.
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.
