IP64 vs IP26
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP64 and IP26 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 2) and liquid protection (level 4 vs 6). IP64 is rated for dust-tight and splashing water (all directions), while IP26 provides > 12.5 mm — finger and powerful water jets (12.5 mm nozzle).
IP64 is dust-tight and resists splashing water from any direction. A solid outdoor-covered rating combining complete dust exclusion with splash tolerance, sitting between IP65 (jets) and IP54 (dust-protected).
Built to withstand protection against solid objects larger than 12.5 mm and protection against powerful water jets. Water projected in powerful jets by a 12.5 mm nozzle against the enclosure from any direction shall have no harmful effects.. Classified as IEC 60529 ingress protection code IP26, it pairs solid level 2 with liquid level 6.

The exact difference (IP64 vs IP26)
Solid protection
IP64
Level 6 — Dust-Tight
IP26
Level 2 — > 12.5 mm — Finger
IP64 provides "Dust-Tight" (level 6), while IP26 provides "> 12.5 mm — Finger" (level 2). IP64 is 4 levels higher.
Liquid protection
IP64
Level 4 — Splashing Water (all directions)
IP26
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP64 handles 50–100 kPa (Splashing Water (all directions)), while IP26 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP26 provides 2 levels more liquid protection.

Recommendation
IP64 offers higher overall protection than IP26. Choose IP64 for harsher environments; IP26 may suffice for milder conditions and can be more cost-effective.
