Weidmüller KLBUE 3-8 FM4 Shield Clamping Saddle for 3-8mm Cable Diameter

The Weidmüller KLBUE 3-8 FM4 shield clamping saddle is a precision-engineered component designed to provide reliable electromagnetic interference (EMI) shielding for cables with diameters ranging from 3 to 8 mm. By ensuring a consistent and low-resistance electrical connection between the cable shield and the grounding system, this clamping saddle helps maintain signal integrity in sensitive industrial environments. Its robust construction facilitates both secure mechanical fixation and optimal electrical conductivity, which is vital for preventing data corruption or signal noise in complex automation systems.

Advantages

This shield clamping saddle offers exceptional performance due to its specialized design that guarantees a large contact surface area, significantly reducing transition resistance. The mechanical stability provided by the clamp ensures that the connection remains secure even under conditions of vibration or thermal expansion. Furthermore, the compact form factor allows for efficient space utilization within control cabinets, making it an ideal choice for high-density wiring configurations where reliability and ease of installation are paramount.

Suitable for

• Industrial automation and control systems
• Control cabinet wiring and panel building
• Shielding communication and signal cables
• Applications requiring protection against electromagnetic interference

This component may not be suitable for applications involving cables outside the specified 3-8 mm diameter range, as the clamping mechanism is calibrated for these specific dimensions. It is also not intended for use in high-power electrical transmission lines where the primary requirement is current carrying capacity rather than signal shielding.

Key specifications

• Cable diameter range: 3-8 mm
• Function: Electromagnetic interference shielding
• Mounting type: Shield clamping saddle
• Application: Industrial control and automation

To use the Weidmüller KLBUE 3-8 FM4, first prepare the cable by stripping the outer insulation to expose the braided shield. Position the shield clamping saddle over the exposed shield area and tighten the screw mechanism until the clamp makes firm, even contact with the cable shield. Ensure that the saddle is properly connected to the grounding rail or mounting plate to complete the electrical path to the ground.

What to consider before purchase

• Verify that the cable diameter falls strictly within the 3-8 mm range.
• Ensure compatibility with your existing mounting rail or grounding system.
• Assess the environmental conditions to ensure the material is suitable for the installation site.

For optimal performance, ensure that the contact surface of the grounding rail is clean and free of oxidation before installing the shield clamping saddle. Regularly inspect the connection during routine maintenance to confirm that the mechanical fixation remains tight and the electrical contact is intact.
