Improving Water and Dust Sealing for Linear Handle Locks in Industrial Cabinets

Sealing performance is critical in industrial enclosures — especially when sensitive electronics are involved. While linear handle locks offer ergonomic and space-saving advantages, achieving an IP65 rating with their design has remained a major engineering hurdle. This white paper walks you through Essentra’s real-world case study where our R&D team overcame sealing challenges with custom gasket design, material optimization, and iterative testing. If you're an engineer focused on ingress protection, ergonomic design, or enclosure reliability, this technical breakdown is essential reading.
