These days, above all, a school’s ventilation system must be efficient. And anything but complicated – so consumers’ preferences when it comes to app-controlled smart home features, including the setup, configuration, programming and control of heating, lights, blinds, air conditioning, door communication or security technology in the home.

And just as buildings have a long service life, connectors must be highly reliable for this purpose – whether for high currents for elevators, blowers and actuators or for small signals from sensors for air quality or temperature.

Within all these industries – such as the heating sector – energy efficiency and environmental friendliness clearly constitutes a dominant contrasting focus. And even alternative concepts like solarthermics, photovoltaics, heat pumps, combined heat and power, wood pellet or fuel cell heating have plenty of room, since we call all modern technical feats home.

The right idea, a neat construction, fully-­equipped laboratories and precise system measurements are the primary steps in our developing projects. With state-of-the-art methods and technologies, we mobilize our established development expertise and our passion for feasibility for your product. It is not only about the creation of unique quality products. It is also about finding an answer for challenges where others fail to find a solution.

With our engineering-based-on-partnership maxim we manifest detailed and integrated made-to-measure solutions for you. How? By applying our comprehensive Building Technology know-how and pairing it with our electrical and electromechanical engineering profession.

From a first talk about technology to the development, the design and the construction of a pre-­production prototype, we are a strong and reliable development partner. And we use creative thinking to turn even individual design and product requests into prime “Made by Lumberg” development quality at our R&D center.

For years the HVAC industry has been striving for the highest energy efficiency and for alternative concepts. Recently, the heat pump, whose CO2 savings make it climate-friendly and future-­proof, has come to the fore, as the technology clearly helps to reduce energy costs.

Whether heat pumps, solar thermal systems, photovoltaics, combined heat and power, wood pellet or fuel cell heating – our connectors are well-established in sophisticated solutions.

We can differentiate between markets. Asia calls for different standards compared to Europe, while European standards differ from those in America. Are V0 or GWT only on your plastics agenda, for example? We can offer both – and more, precision-­made to match your market and for your very requirements.

Today’s modern building technology is becoming more and more intricate, which requires ever-grow­ing expertise about the individual building technology segments. From security and communication technology with control and feedback con­trol, measurement, telecommunications and computer technology, to computer engineering – all are clearly advancing. Our offer for a broad spectrum of signal to high currents covers a large array of connectors for your pioneering ideas.

It is increasingly required that heat produced from electronic components has to be dissipated in order to improve the life and functionality of modern parts. Especially high-power LEDs demand an optimized heat management for tight installation spaces.
As a pioneer in the field of RAST connectors we have developed an edge connector that secures the safe single-sided mating with a PCB. Compatible with our manufacturing e­quip­ment, its mating face leans toward the ver­- satile 2.5 RAST connector used by the billion.

Our proficiency is not limited to connectors alone. The cost-effective overmolding of our connectors for your individual precision components are equally elements of our services portfolio. By using integrated production systems for highly-automated overmolding and naturally, injection mold­ing, we implement runnerless, safe solutions for a cost- and time-efficient application with your product assembly.

At the same time, our sophisticated contacting technology to the cable is retained for you: With overmolded RAST connectors, for example, the insulation displacement technology. Up to the highly individual piercing technology.

Products, solutions, services – with our business seg­ments clearly mapped-out and focusing on technological challenges that we know inside out, we concentrate on your application-specific requirement. With solutions that accommodate everything from catalog products to individual product innovation in closest cooperation with you.

We do more than connectors – we design and de­velop full products and sub-assemblies for you while coordinating product requirements and spe­cifications with you and other suppliers involved. We develop and clarify technical interfaces and control the process.

Our range of manufacture gives us more speed, greater flexibility and added individuality. Good for you to know – in case things are “really urgent”.

Our key technologies are punching, bending, injection molding and assembly – we process a variety of metals and plastics – and we design and build assembly lines for the actual connection.

The right systems technology, degree of auto­ma­tion, product implementation, product planning, efficiency-creating measures and process improve­ments are our day-to-day business for the lifecycle of your customized product.

RAST 1.5: Top Miniaturization Achieved |new by Lumberg

„Home of the RAST Connector“ – Lumberg stands for this like no other connector manufacturer. RAST systems are the foundation of the company‘s success in automotive technology as well. In 1986, RAST 5 with a contact pitch of 5.0 mm made its debut. In the course of miniaturization, the RAST 2.5 system was introduced in 1993, which saved 72 % in size and opened up new applications, especially in building technology.

Now, for the first time, RAST 1.5 in IDT is being launched. Compared to RAST 2.5, it saves another 43 % in size.

The characteristic RAST coding is available as well as the option of fully automated cable assembly. The weight saving due to reduced conductor cross-­sections is then 40 %.

RAST 2.5 for 1 mm PCBs | by Lumberg

Consistent: The RAST-2.5 connector, which has proven itself a billion times over and can be used up to 4 A, has also been further developed. Increasingly, 1 mm PCBs are being used where there are challenges in terms of confined installation spaces, desired weight savings or optimization of cooling, for example in high-performance LED headlights.

The connector now comes with a familiar layout: with contact spacing of 2.5 mm, with secure latching on the 1 mm PCB – and of course with the great advantage of economical and efficient automated cable assembly using IDT.

SmartSKEDD: While direct contacting on the edge of the printed circuit board with RAST connectors is one of our domains, and press-fit technology as an irreversible, solderless connection is our compulsory program, a new type of connector has been added to this line-up: the direct connector for multiple plug-ins and plug-outs that can mate without a corresponding part anywhere on the printed circuit board using Insulation Displacement Technology.
SKEDD technology makes this possible. The individual contact comprises two contact tongues which, when inserted into a plated-through hole in the PCB, retract evenly and produce a solderless, reliable mechanical electrical connection.

Extra robust and reliable:
SnapFit locking

Three solid pins on each casing guarantee a secure positioning and prevent mismating. And there is more: each side of the connector features two snap-fits that lock – or rather: snap – the connector tightly onto the PCB. To release the connector, simply press on the primary lock.
Connectors can be mated without tools, for total convenience when mounting entire sub-assemblies. This enables completely new designs since they can be used right in the middle of a printed circuit board, even on the reverse. Here, reversible mating also facilitates for the first time a simple exchange of components as is required, for example, during servicing. In combination with Insulation Displacement Technology which draws on all advantages offered by automated cable assembly and vouches for the convenient production of even large quantities, our unparalleled solution that literally centers your ideas on the PCB is really smart – or simply: SmartSKEDD.
If a secondary lock is what you need – as is standard under LV 214 – or if your application just calls for that extra measure of retention, you can count on a pre-assembled central pin which increases the retaining force of the entire system to almost 100 N.
