Shield clamps

Shield clamps protect your systems against electromagnetic interference. This interference can lead to malfunctions or even failure of entire systems. To prevent these scenarios, the shield clamps consist of standard-compliant components. In addition to protecting your systems, the shield clamps are used to satisfy the EMC Directive with respect to CE conformity.

Professional shielding with shield clamps

Shield clamps are used both in the control cabinet and in systems to ensure the EMC-compliant wiring of signals, power supplies, and data cables. For reliable and EMC-compliant operation in the electromagnetic interference fields, the appropriate shielding must be ensured. The protection provided by shield clamps prevents both incoming and outgoing interference radiation. The main sources of interference include motor and frequency converters, strong magnetic alternating fields, radio waves, and both the capacitive and inductive couplings of other cables. Manufacturing companies and operators of machines and systems must comply with various legal and normative regulations regarding electromagnetic compatibility. These regulations are also part of CE marking.

SCC shield clamps

You can connect SCC shield clamps one-handedly and without using any tools. The convenient clamping bracket and the non-pressurized contact spring enable a simple and low-fatigue shield connection to be made. At the same time, the design of the contact spring guarantees a reproducible and long-term stable contact quality and compensates any conductor settling effects. The shield connection is flexible, with clamps available for direct mounting, neutral busbar mounting, and DIN rail mounting. For neutral busbar mounting, simply swivel the shield clamps onto the neutral busbar rail and close the lever to secure both the terminal block and the conductor to be connected. For a clearer overview and assignment of the individual shield clamps, the clamps feature large marking areas on the clamping bracket. This simplifies assigning the cable in accordance with the circuit diagram.

SK shield clamps

The SK shield clamps clamp the conductors using a knurled screw. To ensure optimum shielding, the clamps feature a spring-loaded and large-surface pressure plate. Shield clamps are available for direct mounting and busbar mounting for mounting in the control cabinet.

SKS shield connection clamps

The SKS spring-cage shield clamps are available in two mounting types. Choose between mounting on DIN rails or directly on conductive mounting panels. The SKS spring-loaded shield clamps are suitable for cable and conductor diameters from 3 to 20 mm.
