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.

 Connection Systems 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.

 Ethernet Connector Gigabit Ethernet
Cat. 6e field-installable RJ45 connector provides IDC termination up to eight poles. The design can accommodate conductors AWG 27 to 22 and cable outer diameters of 4.5-9 mm in both stranded and solid cables. Other features include tool-free assembly with captive wire manager and clear wire map, and multi-port capability.

 Industrial cable 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.

 Ethernat cable 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.

 terminal blocks

Power Distribution
IEC terminal blocks include a screw-clamp, 80 A power distribution block for up to three wires in, four wires out; are available for either base mounting or DIN rail mounting; and are rated 600 V. Housing is a molded polyamide 6.6 thermoplastic, and offers funneled wiring entry with finger-safe IP20 terminals. It’s UL-listed, CE-certified and RoHS-compliant.

 teminal connectors

Luggable
Modular, open-style ring screw (RSC) and ring bolt (RBO) lug connection terminals are designed to replace traditional barrier blocks and are available in 9 and 13 mm profiles. Unlike barrier blocks, modular RSC/RBO terminals are available in both panel-mount and DIN rail-mount packages. They support feed-through connections and current transformer (CT) shorting within switchgear and control system applications.

 I/O station

Sweet 16
Impact20 fieldbus I/O station has 16 inputs or outputs suited for use in terminal boxes and control panels due to its compact size. The device includes predefined inputs and outputs, port-related shutdown in case of failure, and group diagnostics via the bus. The module’s pluggable spring-clamp terminals feature integrated status LEDs for single-channel diagnostics.

 terminal block adapter

Adapt and Terminate
DB9F-to-5-screw terminal-block adapter connects field wiring to DB9 connectors on USB serial adapters, Ethernet serial servers and other Sealevel RS-485 products with a DB9M connector. With a standard DB9 connector, the adapter works with two- and four-wire RS-485 networks and can be secured to the serial port with thumbscrews to prevent accidental disconnection. The adapter is RoHS-compliant.
