DE - Lock nuts for equipotential bonding

DE - Equipotential bonding lock nuts To ensure permanent bonding between the cable gland and housing in painted or coated housings, a lock nut with 6 teeth which cut into the coating automatically when tightened, thus providing equipotential bonding. Moreover, this type of attachment increases the installation’s resistance to vibration. The Problem ... Painted or powder-coated housing cannot be incorporated directly in the equipotential bonding system. The contact surface must be made clean. ... The Solution The 6 teeth of the lock nut for equipotential bonding scrape into the insulating layers of paint or powder and create a vibration-resistant contact • no surface corrosion. • very lowohm transition: gland/housing. • no need to clean contact surface. • additional increases the installed vibration-resistance through frictional connection.
