Locknut SKINDICHT® SM-PE-M 32X1.5, Brass 52103340

Professional solution for coated enclosures

The SKINDICHT® SM-PE-M M32x1.5 securing nut has been specifically designed for mounting SKINTOP®/SKINDICHT® cable glands inside thin-walled, unthreaded enclosures. This component allows for the creation of only a single through-hole in the enclosure, which simplifies the installation process and ensures tightness.

Design and materials

The nut body is made of high-quality CuZn brass, which has then been nickel-plated to achieve optimal corrosion resistance and an aesthetic appearance. The hexagonal shape with a wrench size of 36 mm allows for easy installation using standard tools.

Product dimensions are precisely defined:

• Thickness: 5.7 mm
• Outer diameter: 41.5 mm
• Thread pitch: 1.5 mm
• Hexagon width across flats: 41.5 mm

Surface nickel plating not only protects against corrosion but also ensures stable electrical contact, which is essential in EMC applications.

Technical and environmental properties

The nut maintains full functionality in extreme temperature conditions - it operates in the range of -60°C to +200°C, making it suitable for both indoor and outdoor applications.

The material is characterized by:

• Resistance to high chemical and mechanical loads
• Halogen-free construction - meets fire safety standard requirements
• UV resistance - does not degrade under sunlight
• Oil resistance - maintains properties in oil-contaminated environments
• Flame-retardant properties - does not spread flame

Application in EMC systems

The key function of the nut is to provide optimal electrical contact by cutting through the insulating layer during tightening using sharp cutting edges. This makes the component ideal for:

• Lacquered enclosures - pierces the paint layer to ensure metal-to-metal contact
• Anodized enclosures - breaks through the aluminum oxide layer for conductivity
• Powder-coated enclosures - pierces through thick polymer insulation

The use of this nut guarantees effective grounding and protection against electromagnetic interference (EMC) throughout the entire installation.

Compliance and certificates

The product has full compliance documentation:

• CE marking - confirms compliance with European directives
• RoHS compliance - free from hazardous substances
• DIN EN 60423 standard regarding metric threads
• ETIM 5.0 Classification Class-ID: EC000940 for cable nuts
