IP07 vs IP40
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP07 and IP40 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 4) and liquid protection (level 7 vs 0). IP07 is rated for no protection and temporary immersion (up to 1 m), while IP40 provides > 1 mm — small wires and no protection.
IP07 is an ingress protection code that ensures no protection against solid objects 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 0 with second-digit (liquid) level 7.
IP40 protects against small tools and wires (1 mm objects) but offers no water protection. Useful for indoor equipment needing finer ingress protection against small debris and tools.

The exact difference (IP07 vs IP40)
Solid protection
IP07
Level 0 — No Protection
IP40
Level 4 — > 1 mm — Small Wires
IP07 provides "No Protection" (level 0), while IP40 provides "> 1 mm — Small Wires" (level 4). IP40 is 4 levels higher.
Liquid protection
IP07
Level 7 — Temporary Immersion (up to 1 m)
IP40
Level 0 — No Protection
IP07 provides "Temporary Immersion (up to 1 m)" (level 7), while IP40 provides "No Protection" (level 0). IP07 is 7 levels higher.

Recommendation
IP07 offers higher overall protection than IP40. Choose IP07 for harsher environments; IP40 may suffice for milder conditions and can be more cost-effective.
