More than ever, people like to spend their time at home – home office is certainly one of the reasons for this, but it only partly explains the “cocooning” trend that has been going on for some time now. Home appliances – generally also referred to as White Goods – form a key segment in the consumer goods market. This covers a large selection of devices, ranging from washing machines and dryers, to refrigerators and freezers, to dishwashers and stoves or microwaves as well as small appliances like modern coffee machines, toasters, blenders, vacuum cleaners and shavers.

More than 38 years ago, this industry created what is termed a Household Appliances Standard – and Lumberg was involved in this development from the very start. RAST connectors were created at the time with the aim of standardizing components, to guarantee conformity for connectors from different manufacturers and to eliminate errors in the production process due to mismated connections, or to simplify the process of the end device’s assembly and minimize faulty wiring. RAST also facilitates the consolidation of connections, which helps to avoid discrete connections and discrete cable harnesses. Advantages, which to this very day have furthered their success in numerous other sectors, including automotive. Lumberg is the RAST specialist here, boasting the broadest and deepest product range.

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 Home Appliance 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.

Lumberg is the specialist for RAST. 30 years ago, we contributed significantly toward the develop­ment of the RAST connector, to support the indus­try with eliminating errors in the production pro­cess due to mismated connections, or with simplifying the assembly when mounting end devices, to pave the way for conformity. This became and has remained a standard to this day. We have continuously advanced the development of RAST con­nectors ever since. Today, we offer the broadest product range the market has to offer – for RAST 2.5 and RAST 5 systems. And now also in the smallest pitch: RAST 1.5.

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 home appliances.

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.
