Beta LaserMike recognises that the accurate measurement of lay length in twisted pairs is a critical factor in Category cable performance. The latest LayScan system enables telecommunication cable manufacturers to dramatically improve product performance, quality and consistency. Until now, the ability to accurately measure the lay length of twisted-pairs at the cabler and twinner stations has been a manual and time-consuming process. This manual process results in inaccurate and unreliable measurements. Factors such as the pair lay length and the variations of the lay in twisted-pair Category cables, such as Cat 5e/6/6a/7a products, directly affects crosstalk performance. Cables that do not meet the far- and near-end crosstalk and product quality specifications wind up being scrapped, significantly costing manufacturers in rework, materials and overall productivity losses. With the focus on producing higher quality cable in less time and at a lower cost, the LayScan measurement system from Beta LaserMike offers manufacturers an accurate and consistent method to measure the lay length of twisted pairs used in telecommunication cables. simultaneously measure four pairs at the cabler to confirm the accuracy of twisted-pair cable construction during production. This non-contact system uses four individual Accuracy is a critical factor The LayScan system enables manufacturers to Sandvik’s new wire, Safeni 52, has precisely the right material characteristics and a new level of feedability that contributes to higher throughput with less downtime. Safeni 52 is a soft magnetic iron-nickel alloy with high magnetic permeability, low coercive force, and a low content of non-metallic inclusions. Its thermal expansion is compatible with glass used in reed switches. Using Safeni 52 wire, reed switch manufacturers can rely on consistently high surface quality, which contributes to the wire’s feedability. It runs through equipment cleanly, contributing to higher production throughput with increased uptime as well as high end-product quality and reliability. Packaging is designed to reduce tangled pails and the wire exhibits remarkable straightness with little cast or helix. Together these benefits give

pair lay sensors and Beta LaserMike’s LaserSpeed length and speed gauge to perform the high-speed lay length measurements. A data acquisition and control system effectively collects and processes each lay length in the cable and allows the full use of the customer’s off-line analysis tools such as trend charts, statistical analysis, or FFT analysis to readily observe, measure, and report systematic lay variations within each lay. Data can be easily stored on a local PC. The LayScan system performs measurements to within 0.025mm (0.001") overall accuracy on the same twisted pair. It can measure lay lengths up to 25.4mm (1") at throughput speeds up to 152.4m/min (500ft/min). manufacturers switching to Safeni 52 wire the potential to take on more business without capital investment. Reed switches incorporating Safeni 52 have a very consistent level of reliability and long operational lifetimes, which will contribute to a high yield with very good quality. Pure Sandvik Safeni 52 wire is produced entirely in-house by Sandvik. The company controls the entire process, from alloy melting and wire drawing through to packaging, and, thus, the quality and reliability of the product. Before leaving the plant, the wire is rigorously tested. In addition, Sandvik’s close proximity to customers worldwide ensures a robust and reliable material supply chain. Safeni 52 wire is available in a wide variety of forms and diameters. Beta LaserMike – USA Website : www.betalasermike.com
