IP37 vs IP62
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP37 and IP62 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 6) and liquid protection (level 7 vs 2). IP37 is rated for > 2.5 mm — tool / wire and temporary immersion (up to 1 m), while IP62 provides dust-tight and dripping water at 15° tilt.
Specified under IEC 60529, IP37 denotes protection against solid objects larger than 2.5 mm and protection against the effects of temporary immersion in water. Ingress of water in quantities causing harmful effects shall not be possible.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 3 with second-digit (liquid) level 7.
Built to withstand dust-tight (no ingress of dust) and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. Classified as IEC 60529 ingress protection code IP62, it pairs solid level 6 with liquid level 2.

The exact difference (IP37 vs IP62)
Solid protection
IP37
Level 3 — > 2.5 mm — Tool / Wire
IP62
Level 6 — Dust-Tight
IP37 provides "> 2.5 mm — Tool / Wire" (level 3), while IP62 provides "Dust-Tight" (level 6). IP62 is 3 levels higher.
Liquid protection
IP37
Level 7 — Temporary Immersion (up to 1 m)
IP62
Level 2 — Dripping Water at 15° Tilt
IP37 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP62 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt). IP37 provides 5 levels more liquid protection.

Recommendation
IP37 offers higher overall protection than IP62. Choose IP37 for harsher environments; IP62 may suffice for milder conditions and can be more cost-effective.
