## Summary description

The Lapp Skindicht SM-PE-M (52103320) is a high-quality brass EMC lock nut designed for secure cable gland installation. This silver-colored M20 nut ensures reliable electrical conductivity and mechanical stability in industrial applications. Supplied in a pack of 100 pieces, it is an essential component for professional electrical installations requiring electromagnetic compatibility and robust fastening.

## Long description

The Lapp Skindicht SM-PE-M M20 brass EMC lock nut is a high-performance fastening component engineered for professional electrical installations. Designed to ensure both mechanical stability and reliable electrical conductivity, this lock nut features specialized cutting edges that penetrate insulating layers during tightening. This process establishes an optimal electrical contact, which is essential for maintaining electromagnetic compatibility in demanding industrial environments.
Advantages
The primary advantage of this lock nut lies in its integrated cutting edges, which eliminate the need for manual preparation of the contact surface by effectively cutting through paint or insulating layers. Constructed from high-quality brass, the nut offers excellent durability and resistance to mechanical stress. Its design specifically supports EMC-compliant installations, ensuring that electrical systems remain protected from interference while maintaining a secure and vibration-resistant connection for cable glands.
Suitable for
Industrial automation and control systems
Electrical cabinets and distribution boards
Machinery requiring electromagnetic interference protection
Applications where reliable grounding is critical
When it may not be suitable
This lock nut is specifically designed for M20 threaded applications and may not be compatible with cable glands of different thread sizes or types. It is intended for use with metallic surfaces where the cutting edges can establish a proper electrical connection; it may not be suitable for use on plastic or non-conductive mounting surfaces.
Key specifications
Thread size: M20
Material: Brass
Finish: Silver-colored
Function: EMC-compliant fastening with cutting edges
Quantity: 100 pieces per pack
How to use
To install the lock nut, place the cable gland through the mounting hole of the enclosure. Thread the Skindicht SM-PE-M nut onto the gland from the inside of the housing. As you tighten the nut, the integrated cutting edges will penetrate any insulating layer or paint on the enclosure surface. Ensure the nut is tightened sufficiently to achieve a firm, vibration-resistant fit and to establish the necessary electrical contact for EMC shielding.
What to consider before purchase
Verify that your cable gland has an M20 thread size.
Ensure the mounting surface is conductive to allow the cutting edges to function correctly.
Confirm the quantity required for your project, as these are supplied in packs of 100.
Usage recommendations
For optimal performance, ensure that the mounting surface is clean and free of excessive debris before installation. Always use appropriate tools to tighten the nut to the manufacturer's recommended torque to ensure both mechanical integrity and consistent electrical conductivity.
