turns the shaft at a constant speed of 57.5rpm and can handle reels of material weighing up to 75lb. The DE600M gives the option for manual reeling and dereeling when desired. Adjustable cones and dog allow the use of reels with arbor holes from 3/4″ to 2-1/8″ inner diameter on both units. Datwyler has developed a continuous unshielded class EA cabling system. The system solution comprises CU 692 4P symmetrical data cable, the KU Plus 1/8 RJ45 module, the KU 24x-sg patch panel, and Cat 6A (IEC) RJ45 patch cables. The system is said to achieve transmission rates of up to 10Gbit/s. The CU 692 4P is an unshielded twisted-pair cable (U/UTP) of 8.5mm external diameter. This AWG23 cablemeets all the international standard requirements of a Category 6A (500MHz) product, with high attenuation reserves and good tensile strength. The KU Plus 1/8 RJ45 module has a robust flame retardant plastic enclosure with a dust protection flap. In conjunction with unshielded Category 6A data cables it allows acceptance testing for class EA permanent links with spare capacity for 10GbE transmissions. Both module and cable also meet the requirements for PoE+. The KU 24x-sg patch panel is an unshielded 19″/1U panel of flame retardant plastic with a metal front and integrated strain 10Gb cabling system

relief. Up to 24 RJ45 Category 6A keystone modules can be snapped into the frame. The vertically offset (staggered) openings ensure effective prevention of alien crosstalk between the unshielded cables.

Lock and hold

Originally developed for the food industries, the Uhing-easylock ® clamping system is now used for production processes using winders or coilers, in the wire and cable industries. The axially displaceable Uhing-easylock features a clamping ring which, when subjected to axial tensioning forces, tilts on the shaft and engages with it. The locking effect is proportional to the tensioning force. In packaging processes the Uhing-easylock holds and locks roll cores of foils or other materials, and can be used to quickly adjust material guides. The clamping module can be operated without tools, and changing the clamping module is quick and easy using only one hand. The lightweight, ergonomicallydesigned clamping module, generating high locking forces on a plain shaft, is available in ten sizes for shaft diameters between 10mmand 40mm. It is suitable for static applications and for driven shafts with unmachined surfaces. The clamping module with integrated positive release is available for shaft diameters between 25mm and 40mm. The required surface hardness of the shaft is at least 55 HRC for a surface roughness Ra of 0.2µm – 0.4µm.
