ᐅ IP rating for doorbell on a wall-mounted post?

Hello,

quick question: I want to install a doorbell button on the wall directly facing the street. The doorbell will be connected to a 27V system. The button is mounted on the wall without any weather protection (facing south, with no overhang).

What IP rating is required? Is IP44 sufficient, or should I opt for a higher rating (e.g., IP67)?

Thanks for your help!

By definition, IP67 would be required. However, since you are using low voltage with no risk, it is not necessary. Is there a picture of the doorbell button?

IP44 is a recipe for a near-future short circuit.
The first digit 6 indicates protection against dust and contact, while the second digit indicates resistance to moisture.

IP44:

• protected against solid foreign objects larger than 1mm (0.04 inches) and against contact with a wire
• protected against splashing water

IP67:

• dust-tight, protected against contact
• protected against powerful water jets
