The Dutch manufacturer of industrial sawing machines, Harwi, is known for the durability, quality and user-friendliness of its products. To increase its own productivity and simplify assembly, Harwi opted for tailored cable assemblies from LAPP. This saves the machine manufacturer four hours per constructed machine, which sums up to an additional machine every two to three weeks. In addition, the installation of the sawing machines on site has been noticeably simplified and the risk of incorrect cabling is reduced. Safety, ergonomics and health – these are Harwi’s current development goals for the industrial sawing machines they have been constructing since 1960. The company from Helmond in the Netherlands is also known for its extremely durable products: “We know that there are Harwi sawing machines that have been in use since my birth, i.e. for over 35 or 40 years,” says Adrian van Mensvoort, Managing Director of Harwi. Three years ago, […]

In the smart factory, machines and systems are increasingly networked. As a result, the topic of electromagnetic compatibility (EMC) is also becoming increasingly important. Especially in industrial plants where frequency converter-controlled motors are used, undesirable currents can increasingly occur on the equipotential bonding (PA) or protective earth (PE) cables. A new, innovative cable design from LAPP reliably reduces leakage currents and makes a decisive contribution to improved EMC in machines and systems. Stripped ÖLFLEX® SERVO FD zeroCM Nowadays, electric motors in process automation are operated exclusively by means of frequency converters. In addition to the advantage of variable speed, this type of control offers considerable improvements in terms of energy and process efficiency. However, due to the principle of control, undesirable side effects occur and leakage currents are generated. The more components are involved, the greater the risk of such disturbances. At the same time, the installation spaces in machines […]
LAPP single core systems The perfect solution for single-core storage, transport, and processing. It can quickly happen that individual boxes or boxed coils are not arranged at their respective workplaces. As a result, these elements can get in the way, and there may even be a risk of tripping over them. In this case, the safety of the spaces is not fully guaranteed. With modules, single cores are protected. You can hang the modules on the bar of the single-core cart or place them on the office cart. Many customers also place these modules in the control cabinet. Their use gives a visually pleasing appearance and a tidy workbench. The systems make for easy handling and storage. With LAPP solutions, single cores are in modules. These can be easily removed and replenished with exact quantities. With the help of the single core cart, several single cores can be transported at the […]
Currently, multimode fibre optic cables of various types are available on the market: OM1, OM2, OM3 and OM4 – cables that are in stock (FOOM). In 2016, the TIA (Telecommunications Industry Association) released a new standard TIA-492AAE fibre optic cable called OM5. Cables and strands with OM5 fibre are still rare from a commercial point of view, however, it is expected that by the end of the year it will be possible to supply the market. What characterizes OM5 Fiber? Basically, it is an OM4 fibre with slight manufacturing changes that allows it to have a better response at wavelengths 850-950nm. This makes it especially useful in applications for 40Gbps, 100Gbps or 400Gbps when using SWDM (Short Wave Division Multiplexing) systems. What is the SWDM System? The SWDM (Short Wave Division Multiplexing) system uses 4 different wavelengths (called lambda λ1, λ2, λ3, λ4) that are multiplexed onto a physical medium […]
Did you know that you cannot use the standard black rubber cables – H07RN-F eg-for human drinking water? Except for CLEAN CABLES, other cables provide an odour, taste or colour to drinking water that is harmful to your health. The European Union (EU), through Directive 98/83/EC, of November 3, 1998, defines the essential quality standards to be met by water intended for human consumption. The directive aims to protect people’s health by establishing hygiene and cleanliness requirements to be met by drinking water in the European Union (EU). It applies to all water intended for human consumption, except natural mineral waters and medicinal waters. Member States shall ensure that drinking water: • Does not contain a concentration of microorganisms, parasites or other substances that represent a potential danger to human health; • Meet the minimum requirements (microbiological, chemical and related to radioactivity) established by the directive. To meet this need, […]

To select a fiber optic cable, it will be necessary to know the following minimum data: • What type of protection should the cable have or the application? • What type of fiber optic? • How many fibers should the cable have? • Length? It is essential to know that the supply value of a fiber optic cable depends on the way it is constructed and the type of protection present in the line. Thus, it is essential to adapt the cable offer to the customer’s needs or application of the cable. Then we point out a cable selector in comparison with the scenario in which it will be applied: In the Next WeekTech info, we will cover the types of optical fiber that exist.
We can offer non-flame-spreading cables, non-fire-spreading cables, and fire-resistant cables. Sometimes there is a tendency to mix the concepts. However, the differences are still significant since fire-resistant cables, in addition to having an excellent reaction to fire, like the first ones, allow the circuit to be kept in operation for a few minutes in the presence of a fire. They are allowing the security systems to act correctly. Below is a summary table of the standards used in tests for each case of behaviour and fire resistance.
