7. THEORY OF OPERATION
7.1 Ingress Protection IP20
Ingress protection rates the degree of protection provided by mechanical casings
and electrical enclosures against intrusion, dust, accidental contact, and water under
specified conditions. The IP20 rating indicates that the product is touch-proof and
resistant to dust or objects larger than 12 mm. However, it has no protection against
liquids, so it is susceptible to damage if it comes into contact with water sprays.
IP codes guide suitability for use under different environmental conditions. IP
ratings do not indicate fitness for purpose or confer a performance guarantee.
