IP35 vs IPX7
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP35 and IPX7 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 0) and liquid protection (level 5 vs 7). IP35 is rated for > 2.5 mm — tool / wire and water jets (6.3 mm nozzle), while IPX7 provides no protection and temporary immersion (up to 1 m).
Built to withstand protection against solid objects larger than 2.5 mm and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. Classified as IEC 60529 ingress protection code IP35, it pairs solid level 3 with liquid level 5.
IPX7 resists temporary immersion up to 1 meter for 30 minutes, with solid protection not specified. Common for portable electronics that may be dropped in water.

The exact difference (IP35 vs IPX7)
Solid protection
IP35
Level 3 — > 2.5 mm — Tool / Wire
IPX7
Level 0 — No Protection
IP35 provides "> 2.5 mm — Tool / Wire" (level 3), while IPX7 provides "No Protection" (level 0). IP35 is 3 levels higher.
Liquid protection
IP35
Level 5 — Water Jets (6.3 mm nozzle)
IPX7
Level 7 — Temporary Immersion (up to 1 m)
IP35 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IPX7 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)). IPX7 provides 2 levels more liquid protection.

Recommendation
IP35 offers higher overall protection than IPX7. Choose IP35 for harsher environments; IPX7 may suffice for milder conditions and can be more cost-effective.
