The operator interface includes a choice of all phase and chord gates and a new probe screen offers sensitivity and phase adjustment for each individual channel. Throughput speeds of up to 4m/s (800fpm) are said to be achievable, with larger diameters requiring slower speeds. The tester operates at up to 1,500 rpm, depending on product diameter. MAC’s AC flux leakage systems use two magnetization yokes and alternating current to induce an alternating magnetic field. Without contact, these yokes magnetize the test material in the transverse direction. Due to an eddy current effect the magnetic flux is concentrated on the material’s surface, and is particularly sensitive to minor surface defects. USB safety L-com Global Connectivity has released a new series of low-smoke, zero-halogen (LSZH) USB cables with ferrites, designed to protect people and equipment from toxic and corrosive gases in poorly vented areas. Many industrial, oil and gas, rail, military and government installations include areas with little ventilation and that expose electronics to severe temperatures and/or flammable chemicals. Though many USB-powered test, monitoring, control, location and portable electronics used in these environments are ruggedized to operate safely under these

during the fabrication process, before painting or powder coating, self-clinching fasteners become integral components. The new plugs and film ensure that paints or powder coatings will not impact the thread integrity of installed fasteners as assemblies move through production. The plugs and film can reduce labor requirements by eliminating the need to mask fastener threads inadvanceofcoating processes, or to clean contaminated threads. Plugs are engineered to withstand temperatures up to 482ºF and 250ºC, and fasteners with the feature can be installed automatically. Looking (slightly) below the surface Magnetic Analysis Corp has introduced its Rotoflux ® AC flux leakage tester, suitable for testing hot rolled black steel bars and rods with surface conditions that make finding shallow defects difficult, if not impossible. MAC’s latest model is designed to test bar from 15mm to 130mm, detecting longitudinal flaws as small as 0.1mm deep, depending on surface conditions. Two surface-ride probe arrays, each with eight elements, cover up to 160mm per rotation. A simple adjusting tool allows quick resetting for dimensional changes, and triple guide roll assemblies on incoming and outgoing sides swing open for easy access.
