Fermacavo DeLOCK 66440

The DeLOCK 66440 cable clamp is a metal shield clamp designed to fix a cable with a diameter of 3–8 mm onto a 35 mm DIN rail. Made of metal, the clamp also functions as an EMC shield, conducting and dissipating unwanted electrical or electromagnetic interference from the DIN rail. Its compact dimensions (18 mm width, 26 mm depth, 14 mm height) provide a secure and durable mounting solution for cable routing and strain relief.

Advantages

The metal construction provides mechanical strength and durability while enabling electromagnetic compatibility (EMC) shielding. The clamp supports cables with diameters from 3 to 8 mm and can be mounted quickly to a standard 35 mm DIN rail. It may be fixed additionally with a screw using an Allen key size HX3 for a more secure attachment.

Suitable for

• Securing single cables (3–8 mm) to 35 mm DIN rails
• Applications requiring basic EMC shielding on DIN rails
• Cable routing and strain relief in control cabinets and electrical panels

How to use

To fasten a cable, press the spring section of the clamp down using a suitable tool such as a screwdriver, insert the cable into the clamp opening and release the spring so it holds the cable. To detach the cable, press the spring down again together with the cable and withdraw the cable. For a more permanent attachment the shield clamp can be secured to the DIN rail with a screw using an Allen key size HX3.

Recommendations

Use the clamp only with cables that match the specified 3–8 mm diameter range. When using the clamp for EMC shielding, ensure proper contact between clamp and DIN rail and secure with the HX3 screw if required for improved conductivity and mechanical stability.
