An IP45 enclosure's protection relies on multiple structural elements. Door-to-body fit, gasket continuity, latch compression, hinge placement, and cable gland sealing all affect solid and water ingress resistance.

When designing cable entries, verify cable quantity, diameter, entry direction, bend radius, and maintenance clearance. For top, bottom, or side entries, evaluate water accumulation risks and ensure cable glands match the target IP rating.

Vents, viewing windows, pushbuttons, displays, and connectors can also create ingress vulnerabilities. For custom IP45 enclosures, finalize seals, fittings, and mounting methods during the cutout drawing stage rather than focusing solely on sheet metal protection.
