The blind plug SKINDICHT® BL-M32X1,5 from Lapp is a metallic closure for unused metric threaded holes in housings. It is used for sealing and mechanical protection of holes with a thread of M 32, protecting unused openings from dust, moisture, and mechanical influences. The product is made of brass and nickel-plated, ensuring high corrosion resistance and long service life even under demanding conditions. It is particularly used in electrical and automation technology, where secure and durable sealing of housing openings is required.

Applications

The blind plug is suitable for outdoor use and withstands high chemical and mechanical stresses. It is therefore suitable for industrial applications as well as environments with increased humidity or aggressive media. UV resistance ensures that the product does not undergo material changes or cracking even under prolonged sunlight exposure. The maximum operating temperature is +200 °C, enabling use in thermally stressed environments.

Functions and Features in Detail

The product is halogen-free and thus meets requirements for environmentally friendly materials. The nickel-plated surface provides additional protection against oxidation and corrosion. Article numbers ending in 'LF' represent lead-free alternatives that may become mandatory in the future according to the RoHS directive. These variants omit the addition of lead, which can amount to up to four percent in copper alloys. Installation is simple using a flat-head screwdriver, ensuring quick and secure mounting.

Technology Explained Simply

The blind plug is screwed into a metric threaded hole with M 32 to achieve a tight seal. The nickel-plated brass alloy ensures high mechanical strength and chemical resistance. UL certification enables use of the product in the North American market, with exact certification data to be taken from the technical documentation.

Compatibility and Accessories

The blind plug is specifically designed for metric threaded holes with M 32. It is compatible with standard threads according to DIN 13, commonly used in electrical and machine engineering. No additional tools are required other than a flat-head screwdriver.

Installation and Mounting

Mounting is done by screwing the blind plug into the corresponding threaded hole. The simple handling with a flat-head screwdriver enables quick and precise installation. It is important to ensure the hole is clean and free from dirt or contamination to guarantee a tight seal. No additional mounting aids or tools are required.

Operational Advantages

The blind plug provides reliable sealing and mechanical stability. High temperature resistance up to +200 °C, as well as UV and chemical resistance, ensure long service life even under extreme conditions. The halogen-free and lead-free design complies with modern environmental standards. Easy installation reduces installation effort and error susceptibility. UL certification expands the application range into the North American market.
