New brackets allow Murrplastik cable drag chains to do even more

This latest development means cable drag chain systems from Murrplastik Systemtechnik GmbH can now do more than just connect a power, hydrau-lic oil, air, water, gas or steam supply to mobile equipment.

Cable drag chain systems made by Murrplastik Systemtechnik, Oppenweiler (nr. Stuttgart) are a smart solution: they supply mobile equipment with both power and data. Without an “umbilical cord” of this kind – which routes and protects the embedded, flexible cables or pneumatic/hydraulic hoses and ensures that the smallest possible bending radius can be maintained – the equipment’s supply lines would be rendered unusable in no time at all.

Thanks to the innovative skills of engineers at Murrplastik, the impressive utility of the Swabian-produced cable drag chains can now be improved still further. The basic idea couldn’t be simpler: instead of using the chain only on the equipment’s supply side, enhance the system so that it can also be used for waste ducting. Often, such enhancements use tubing made from many kinds of materials, for the suction removal of airborne particulates or welding gas at the workplace. In woodworking, too, waste – chippings and sawdust – very often needs removal by suction. Thanks to the existing modular system, it is now very simple to ensure the safe routing of this kind of suction tubing by using the new Murrplastik brackets attached to the PowerLine range of cable drag chains.

The brackets for suction tubing are either mounted on the frame bridges or (for closed chains) on the plastic or aluminium covers. With open chains, the brackets snap onto the frame bridges. If the chains are equipped with closed covers, then the brackets are bolted onto the covers. Tubing can be attached to the inside or outside bend of the chain. No modifications are made to the chains themselves. Accordingly, the standard shelving systems continue to be usable within the chain: these maintain the proper position of the various services, ensuring lines can move freely but not become twisted. If an application already has cable drag chains installed, then it is also very simple to retrofit the brackets to the system. If a piece of tubing needs replacing, the bracket can be removed and re-attached without difficulty and without needing to open up the chain. Since many different diameters of tubing are available, brackets can of course be supplied in several sizes.

Standard guide channel systems (VAW) from Murrplastik can be used to route the chains. We can supply matching adapters for this scenario, ensuring that the chain and brackets have sufficient clearance.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
