Lapp SKINTOP ST-M 53111250 Polyamide Cable Gland M40 x 1.5 Black

The Lapp SKINTOP ST-M 53111250 is a professional-grade polyamide cable gland engineered to provide secure cable entry and effective strain relief in demanding industrial environments. Designed with an M40 x 1.5 metric thread, this component ensures a robust connection for cables passing through enclosures or panels. Its durable black polyamide construction offers excellent resistance to chemicals and mechanical stress, making it a reliable choice for long-term electrical installations where protection and stability are paramount.

Advantages

This cable gland stands out due to its high-performance sealing capabilities, which meet the IP68 protection standard, ensuring the assembly is completely dust-tight and waterproof even under submersion. The integrated strain relief mechanism prevents cables from being pulled out or damaged, thereby extending the service life of the connection. Its lightweight yet impact-resistant polyamide material provides a versatile solution that maintains structural integrity across a wide range of temperatures and environmental conditions.

Suitable for

• Industrial control panels and distribution boxes
• Automation and robotics equipment
• Electrical machinery and manufacturing plants
• Outdoor installations requiring moisture protection

This cable gland may not be suitable for applications involving extreme heat sources or environments where the material is exposed to concentrated acids or solvents that exceed the chemical resistance limits of polyamide. It is also not intended for use in high-pressure steam cleaning environments or areas requiring metallic shielding for electromagnetic compatibility.

Key specifications

• Thread size: M40 x 1.5
• Material: Polyamide
• Protection rating: IP68
• Color: Black
• Function: Strain relief and cable sealing

To install the gland, insert the cable through the opening and tighten the cap onto the base until the internal seal compresses firmly around the cable jacket. Ensure the thread is properly aligned with the enclosure port to prevent cross-threading. The gland should be tightened using a standard wrench to achieve the specified torque, ensuring the seal is fully engaged to maintain the IP68 rating.

What to consider before purchase

• Verify the outer diameter of your cable matches the clamping range of the M40 gland
• Ensure the enclosure wall thickness is compatible with the thread length
• Confirm the environmental temperature range of your application

For optimal performance and to maintain the IP68 integrity, ensure the cable is inserted straight and the cap is tightened evenly. Avoid over-tightening, which could damage the plastic threads or the internal sealing ring.
