The speed at which software features and tools are introduced makes it tempting to think that hardware doesn’t evolve. That would be a mistake. As more users get hip to fieldbuses, Ethernet and wireless—and as these technologies get progressively less expensive—these innovators are taking sensors and I/O points out to more and different devices and applications where they haven’t been used before.
Consequently, this is fueling revived interest in and implementation of many terminal block and connector products, as well as demand for newer solutions as users try to meet previously unexpected needs they’re encountering in these new environments.

Fit for Water Mini-Fit H2O weatherproof, compact connection system is designed for wire-to-wire applications to 9.0 A per circuit. IP67-rated, it consists of plug and receptacle assemblies and male and female crimp terminals. The plug and receptacle assemblies have a pre-installed interface and wire seals, for a lower applied cost compared with connectors with manually installed seals. It is suited to tight-space applications, such as those in automotive, lighting systems and medical devices. Molex 800/786-6539 www.molex.com |

Quick Custom ITC/PLTC cables offer exposed-run instrumentation and control wiring for factory-floor automation equipment, material handling, sensors and transducers, process controls and other applications. The cables eliminate the need for conduit in most installations and reduce material and installation costs. They are UL-listed and approved for wet and Class 1, Div. 2 hazardous areas. Custom cable is shipped in five days or less with no minimum length or quantity. Northwire 800/468-1516 www.northwire.com |

Patch That 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.

Bus Terminals HD bus terminals have 16 digital I/O channels in the housing of a 12 mm electronic terminal block. Using Beckhoff bus couplers or DIN-rail-mounted controllers, the terminals are compatible with almost every major fieldbus. The terminals come in Beckhoff bus and EtherCat versions, and are available as 16-channel terminals for digital inputs or outputs; as eight-channel terminals for digital inputs or outputs with two-wire connection; or as combination terminals with eight digital inputs and eight digital outputs.
