Weidmüller’s products address key challenges in industrial automation by providing reliable, durable, and easy-to-install solutions
Industrial plants and building infrastructures are becoming increasingly complex. This makes them more sensitive to surge damage. In addition, digitization is increasing the number of connections and data streams that must not be interrupted. Reliable lightning and surge protection ensures system availability, protects against data loss, and increases added value.
Weidmuller has had standard-compliant lightning and surge protection products in its range for many years and develops customized surge protection solutions with maximum reliability. The proven surge protection devices of the VARITECTOR series are available for power systems, I&C components, and data interfaces.
“HDC’s” are used wherever there is a need for a secure, simple and time-saving assembly of machinery and facilities. The connector housings are made of die-cast aluminium and offer excellent protection against dirt, moisture and mechanical stress. Special modular connectors make it possible to integrate signals, power supply and data connections into a single connector. With the RockStar® heavy-duty connectors, Weidmüller offers a product line with many patented innovations that is oriented towards the future. What other suppliers offer only as a custom configuration, Weidmüller supplies in its standard product line.

The conductor is simply inserted in the clamping unit for a safe, gas-tight connection. Even flexible conductors can be connected easily and without tools. Safe and reliable connections are crucial, especially under harsh conditions, such as those in the process industry. Our PUSH IN technology guarantees excellent contact security and ease of handling, even in demanding applications.
FEATURES & BENEFITS:
- Release Conductors Without Tools
- Flexible mounting foot compensates for different terminal rail dimensions
- Clear differentiation of functional areas
- Slim design for add space in the cabinet

Klippon Connect Terminal Blocks with Push In Technology
Whether in machine 
construction, the automotive industry or railway and shipping: wherever there is a requirement for a
particularly vibration-resistant contact,tension clamp technology proves extremely reliable. At the same time, our terminal
blocks with proven tension clamp technology are perfect for compact yet manageable panel construction. The wide range
with numerous additional functions and pluggable terminal blocks (WeiCoS), the wide clamping range and up to two
cross-connection channels make the Z-Series perfectly adaptable to all requirements. Pluggable standard cross-connections
enable flexible potential distribution.
The Z-Series has an impressive, practical design and comes in two variants: standard and roof. Our standard models cover
wire cross-sections from 0.05 to 35 mm2. Terminal blocks for wire cross-sections from 0.13 to 16 mm2 are available as
roof variants. The striking shape of the roof style gives a reduction in length of up to 36 percent compared to standard
terminal blocks. Despite their compact width of just 5 mm (2 connections) or 10 mm (4 connections), our block terminals
guarantee absolute clarity and ease of handling thanks to the top-entry conductor feeds. This means the wiring is clear
even in terminal boxes with restricted space.
FEATURES & BENEFITS:
- Pluggable standard cross-connections for flexible potential distribution
- Integrated test point
- Can be wired without special tools
- Separable electrical and mechanical functions
- Simple handling thanks to parallel alignment of conductor entry
Klippon® Connect sets standards with clamping yoke technology
Whatever your requirements for the panel: our screw connection system with patented clamping yoke technology ensures the ultimate in contact safety. You can use both screw-in and plug-in cross-connections for potential distribution. Two conductors of the same diameter can also be connected in a single terminal point in accordance with UL1059. The screw connection has long been an established connection element to meet exacting demands in terms of reliability and functionality. And our W-Series is still setting standards.
Thanks to the range of models and real flexibility, our terminal blocks with clamping yoke technology can be used in a wide range of different applications. 
Numerous national and international approvals and qualifications in accordance with a variety of application standards make the W-series a universal connection solution, especially in harsh conditions. Weidmuller’s terminal blocks with clamping yoke technology are available in both standard and compact designs. The compact design covers wire cross-sections from 0.05 mm2 to 150 mm2 and helps save space in the panel. The standard version covers conductor cross sections of up to 240 mm 2 . The identical contours of the terminal blocks make configuration easier and reduces the quantity of accessories required.

For Reliable Power Transfer
There are a lot of challenges for connectivity – especially in transportation; whether it is the supply of high power levels to engines, the quick and safe coupling of carriages as well as their energy distribution, traffic engineering in general, or high-speed trains especially. For reliable power transfer in these challenging conditions, we offer series WF, WFF, and ST 400 stud terminals. With crimped cable lugs, the conductors are laid on the threaded pins and securely connected together by tightening the hex nut to the required torque. The robust processing guarantees the ultimate in safety.
In all applications where reliable power transfer is key, our stud terminals are the safe solution. The WF and WFF stud terminal series are available as single and two-stud terminals. The option of a built-in folding hinged hood gives the two-stud terminals in the WFF-Series a particularly high level of safety.
The ST 400 stud terminals, made of glass-fibre reinforced, flame resistant artificial resin for operating voltages of up to 4 kV, are specially designed for use on rail vehicles and tested to meet railway standards. They are perfect for applications with high requirements in terms of vibration and shock resistance.
FEATURES & BENEFITS:
- Designed for voltage ranges up to 4,000 V and currents up to 700 A
- Extensive portfolio of one and two stud terminals
- Safe operation due to cover profiles or hinged hoods (snap-on/screwable)
- Materials comply with fire prevention regulations acc. to DIN EN 45545
- Simple handling – all that is required is a torque wrench

HDC Connectors
Heavy Duty Connectors RockStar ®
Robust and reliable industrial connector system designed for demanding applications. These connectors are used in environments where high mechanical and electrical performance is required, such as in machinery, transportation, energy, and industrial automation.
Industrial Connector Range of Fixed Pole Inserts & IP65 Housings
A heavy-duty connector consists of a connector insert and its protective housing. The insert is therefore the heart of the heavy-duty connector. It is responsible for electrical functioning. Connector inserts from Weidmüller are made from high-quality insulation materials, which allow secure transmission of high voltages in a tight space. Moreover, we use only a single type of plastic in our entire product line. This plastic is UL listed, and suitable for railway applications. This allows unlimited world-wide use of the RockStar® connector.
RockStar® ModuPlug: Modular connectors 
Thanks to the new variety of module sizes, you can fit more applications than ever before in one plug-in connector.
The modules reduce the amount of space required and cut costs when compared with fixed-pole inserts and other modular plug-in connector systems.
The sophisticated frames and modules can be installed with extreme ease and integrated into HDC enclosures with the IP65 and IP68 protection classes.
You can even use the RockStar® ModuPlug to supplement existing applications without any need to make system adjustments.
-Optimum use of installation space and high flexibility thanks to the new module widths “Half 0.5” and “Single Plus 1.5”
-Simple and safe assembly of the coded modular modules and the unique slide frame
