The Robot POS series have been approved with IP43 certification (International Protection 43). This standard classifies the sealing effectiveness of enclosures of electrical equipment against the intrusion of foreign bodies and moisture.
Robot POS series have constant waterfall Internal silicon washers which maintain moisture resistance.
So what is International Protection 43? It is not just a number; the first numeral “4” indicates the protection against solid foreign objects with a diameter greater than 1.0mm. The second numeral “3” indicates the protection against splashing water. To pass this test, the Robot POS series are placed in a chamber with water spraying at an angle of 60 degrees on either side of the unit for 10 minutes.
