Double-Level Disconnect Terminal Block – Half the Width

UTTB 4-MT and TG disconnect terminal blocks, which are the same shape as UTTB 2.5 and 4 mm² feed-through terminal blocks, are now available. In signal wiring applications, an increasing number of contact points have to be wired in the same amount of space. The potentials routed on two levels reduce space requirements by 50% compared to single-level terminal blocks. In order to implement a wide range of switching tasks, especially in measuring and control technology, a disconnect knife or isolating connector, a component connector or a fuse connector for 5x20 glass tube fuses can be used in the standardized CLIPLINE complete disconnect zone of the top level. Measuring instruments can be looped in via the connection screws with an integrated test socket, which means that voltage and current measurements can be performed at any time in both levels without interruption. The offset levels thus simplify the operation of the bottom level.

All modular terminal blocks in the UT product group have been implemented within the framework of the CLIPLINE complete system for use with cross-system accessories.

In addition to the same bridging system, the accessories for labeling and testing are the same as those for spring-cage, spiral spring, and QUICKON IDC connection technology.

RJ-45 and M12 Plug Connectors for Ethernet and Profinet

The quick connection technology of the new four-pin M12 Quickon and eight-pin RJ-45 Quickon products from Phoenix Contact make tool-free connections possible for the first time even under harsh conditions in industrial environments. Both plug connectors are extensively shielded and correspond to CAT5 in accordance with IEC 11801:2002. The generous AWG 26-22 cross-section range for single-wire and seven-wire cables makes it possible to connect all common types of Ethernet and Profinet cables.

In industrial environments, Ethernet cabling is increasingly migrating away from RJ-45 to M12 connectors, which are also used in sensor/actuator applications: For this reason, Phoenix Contact has expanded its comprehensive product range for RJ-45 and M12-based Ethernet and Profinet cabling to include connectors available in protection categories IP 20 and IP 67, pre-assembled wires, cables in meter lengths and patch panels for DIN rail systems in control cabinets.

Fiber Optic Plug Connector with Quick Connection Technology for Polymer Fibers

The SCRJ Variosub plug connector from Phoenix Contact is the first IP 67-compliant fiber-optic plug connector with quick connection technology available on the market. The small form factor (as per EN 50377-6-1 or IEC 61754-24) and the 2.5 mm ferrules of the plug connector make it particularly well-suited for 980/1000 µm polymer fibers. The polymer fiber is used for industrial-grade fast Ethernet cabling with transmission lengths of up to 50 m and is therefore often installed in machine shop environments. Given the harsh conditions that prevail in such environments, robust plug connectors and easy connection techniques are needed.

The field-assembly plug connectors for polymer fibers are available in IP 20 and IP 67-compliant models. Owing to the easy handling, connecting the plug connectors is possible even under the harsh conditions of industrial environments. Phoenix Contact also offers sufficiently robust cables in meter lengths and as assembled wires for fiber-optic cabling.

The plug connector is also available for HCS and glass fibers. The connector is thus suitable for all fiber optic-based data transmissions in harsh environments in the fields of automation, industrial building cabling, traffic control, and telecommunications.

Universal Networking for Building Automation

Phoenix Contact has developed the new BC line of housings for future-oriented applications in building installations. Its conformance with the DIN 43880 norm makes it easy to use with all standard distributor boxes. Various widths and interior PCB guide grooves in all three spatial directions offer the necessary flexibility when designing devices. Combined with transparent and hinged—or colored and fixed—housing covers, various devices can be set into the same housing design.

To respond appropriately to increased networking in building automation, these housings can be combined with rail-mounted bus connectors with high pin counts. The 16-pin cross-connector supplies not only the serial and parallel data transmission, but also the power source. It saves on time needed for wiring, removes potential sources of error such as improper wiring, and is the solution for the growing demands on flexibility and performance for data utilization in building automation. Translational plugging and unplugging of individual devices is very easy and is possible without disturbing module groups. This means that signal transmission is not interrupted. Devices can be exchanged and functionality can be added without having to perform any additional rewiring work.

Professional PCB connection technology rounds out this line of housings. Various installation depths make it easy to select any terminal block, while interior housing dimensions have been maximized for convenience.

Space-Saving High-Performance PCB Terminal

The new MKDS 10 HV is a high-performance PCB terminal from Phoenix Contact and its clever pin arrangement with a pitch as small as 10.16 mm has been given unlimited 600 V UL approval (800 V in accordance with VDE). This makes is particularly suitable for products intended for the international market. With a flexible 16 mm² connector cross-section, it can transfer currents up to 76 A at ambient temperatures of approx. 60°C. For smaller connector cross-sections and currents, the current carrying capacity curve must be taken into consideration. The wire connection utilizes the tension sleeve principle to screw into this terminal.

The PCB terminal consists of individual terminals that can be combined for any number of pins. In this way, color codes can be applied for each pin number.

PROFIBUS Solutions from Phoenix Contact: From the Control to the Sensor

Phoenix Contact offers a comprehensive product range which makes it easy for you to implement integrated PROFIBUS solutions fast. I/O systems, for example, are available in both modular and block design.

Whereas INLINE modules with IP20 protection are used in the control cabinet, FIELDLINE components with IP65/67 protection are designed for field installation. Infrastructure components, such as fiber optic (FO) converters and repeaters, provide support for the design of user-specific bus topologies, which can be implemented in copper or fiber optic technology as required. Our cables and connectors can be assembled on site within just a few minutes thanks to the SUBCON-PLUS or F-SMA/B-FOC fast connection system. Our PROFIBUS portfolio is rounded off with intelligent motor starters and various gateways, which establish the connection to other bus systems...
