Signal terminals with a screw connection provide a durable and secure connection to the PCB and have been among the well-established connection solutions in industrial electronics for decades. Whether using clamping yoke or leaf spring screw connection, both variants guarantee high contact security and reliable conductor fixation even under demanding operating conditions.
The screw connection system is convincing due to its robustness, high clamping forces and suitability for a wide variety of types of conductor and cross-sections. It is particularly well suited to applications where a permanently stable connection is needed, even in the face of vibrations, temperature fluctuations or mechanical stress.
With module sizes ranging from 3,50 mm to 10,16 mm and various designs – from compact to multi-tier – these terminals offer a high degree of flexibility for a wide variety of PCB layouts. THT variants allow for easy integration into established manufacturing processes and support cost-effective device production.
Thanks to their intuitive operation and clear visual monitoring of the wiring, screw terminals are ideal for control panel applications, power distribution, and measurement, control, and regulation technology. They are selected when maximum reliability, ease of maintenance and versatility are required.
Thanks to their combination of proven technology, high contact quality and versatile applications, Weidmüller’s screw-type terminal blocks support the development of safe, efficient and sustainable equipment.
Weidmüller’s PCB terminal blocks with screw connection are synonymous with tried-and-tested, reliable connection systems and are regarded as the market standard. With the most comprehensive range of terminals on the market, they offer a wide variety of variants for connection cross-sections ranging from 0.08 to 25 mm², current-carrying capacities of up to 101 A, and a variety of wire outlet directions and housing designs. Thanks to their maintenance-free screw locking mechanism, high contact reliability and flexible processing of both solid wires and flexible conductors, they are ideal for safe use in any range of equipment.
Thanks to the 90°, 135° and 180° conductor output angles, all design options are possible.
Single- and multi-tier variants allow for use in a wide variety of installation scenarios and ensure optimal use of space whilst maintaining a high package density.
The standard technology – tried and tested, compact and cost-effective: PCB terminal blocks with push-in or screw connections
PCB terminal blocks can be flexibly mounted side by side without losing any poles or connections, ensuring maximum efficiency in equipment assembly.
OMNIMATE® Signal PCB terminal blocks are used throughout the industrial electronics sector wherever signals need to be connected to the PCB with reliability, compactness and long-term security.
A heat pump is a device that transfers thermal energy from a cooler place to a warmer one. It uses the temperature difference in the environment to absorb and transfer heat. The system operates in a continuous cycle of evaporation, compression, condensation and expansion, thereby efficiently transferring heat. Compared to conventional heating systems, a heat pump requires less primary energy, as most of the heat is drawn from the environment. It therefore represents an energy efficient and environmentally friendly solution for heating or cooling buildings.
An HVAC system regulates temperature, air quality, and humidity to create a comfortable indoor environment. It combines heating, cooling, and ventilation and is used in residential, commercial, and industrial buildings. The installation is typically located outside the building or on the roof. The system architecture includes a power supply, a controller board for central processing, as well as a control unit for sensors and actuators that captures measurement data and manages control processes. Integrated communication interfaces enable data exchange with higher‑level building management systems. The system is typically installed outside the building or on the roof.
As experienced experts, we support our customers and partners around the world with products, solutions and services in the industrial environment of power, signals and data. One the one hand, it allows us to produce controllers that are increasingly sophisticated. We are therefore continuously developing innovative, sustainable and value-adding solutions for their individual needs. You also have to consider industry-wide standards and of course keep automation expertise at the highest level too.
Stricter requirements in building safety are becoming increasingly important and thus necessitate the use of future-proof monitoring systems. Besides fulfilling legal regulations and standards, such as DIN VDE 0833, it must be ensured that the equipment reliably protects people and property.
Screw connections provide a particularly reliable, maintenance-free connection. They enable conductors of various cross-sections to be securely fastened, are vibration-resistant and provide a clear visual check of the connection. Thanks to defined torques, a reproducible, durable connection is guaranteed.
OMNIMATE® Signal PCB terminal blocks cover all relevant cross-section ranges up to 6 mm².
The terminals are available in all standard module sizes from 3,50 mm to 10,16 mm. Compact, multi-tier designs allow for a number of poles up to 72, enabling a high connection density.
Multi-layer designs save valuable space on the PCB, increase connection density and enable compact device architectures without compromising on accessibility or maintenance.
