How to use
To install the Lapp SKINDICHT MR-M, first ensure that the cable gland and the enclosure opening are clean and free of debris. Thread the reduction nut onto the existing M20 opening of the housing or equipment. Once the adapter is securely in place, you can proceed to attach the M16 cable gland to the outer side of the reduction nut. Tighten the components using appropriate tools to ensure a firm fit, taking care not to overtighten, which could damage the threads.
What to consider before purchase
Verify that your enclosure opening is M20 and your cable gland is M16.
Ensure the environment is compatible with nickel-plated brass materials.
Confirm the required quantity for your specific project needs.
Usage recommendations
Always use calibrated tools to tighten the lock nut to prevent thread stripping and ensure the integrity of the electrical connection. Regularly inspect the installation for signs of vibration-induced loosening in high-movement environments.
