IP27 vs IPX7
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP27 and IPX7 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 0). IP27 is rated for > 12.5 mm — finger and temporary immersion (up to 1 m), while IPX7 provides no protection and temporary immersion (up to 1 m).
The IP27 classification guarantees protection against solid objects larger than 12.5 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 2 with second-digit (liquid) level 7.
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 (IP27 vs IPX7)
Solid protection
IP27
Level 2 — > 12.5 mm — Finger
IPX7
Level 0 — No Protection
IP27 provides "> 12.5 mm — Finger" (level 2), while IPX7 provides "No Protection" (level 0). IP27 is 2 levels higher.
Liquid protection
IP27
Level 7 — Temporary Immersion (up to 1 m)
IPX7
Level 7 — Temporary Immersion (up to 1 m)
Both IP27 and IPX7 share the same liquid protection: Temporary Immersion (up to 1 m).

Recommendation
IP27 offers higher overall protection than IPX7. Choose IP27 for harsher environments; IPX7 may suffice for milder conditions and can be more cost-effective.
