IP26 vs IP52
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP26 and IP52 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 5) and liquid protection (level 6 vs 2). IP26 is rated for > 12.5 mm — finger and powerful water jets (12.5 mm nozzle), while IP52 provides dust-protected and dripping water at 15° tilt.
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.
IP52 is an ingress protection code that ensures dust-protected (limited ingress, no harmful deposit) and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 5 with second-digit (liquid) level 2.

The exact difference (IP26 vs IP52)
Solid protection
IP26
Level 2 — > 12.5 mm — Finger
IP52
Level 5 — Dust-Protected
IP26 provides "> 12.5 mm — Finger" (level 2), while IP52 provides "Dust-Protected" (level 5). IP52 is 3 levels higher.
Liquid protection
IP26
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP52
Level 2 — Dripping Water at 15° Tilt
IP26 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IP52 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt). IP26 provides 4 levels more liquid protection.

Recommendation
IP26 offers higher overall protection than IP52. Choose IP26 for harsher environments; IP52 may suffice for milder conditions and can be more cost-effective.
