The IP60 ingress protection rating signifies a level of protection against dust and water. The first digit, '6', indicates complete protection against dust ingress, meaning no particles are able to penetrate the device. The second digit, '0', identifies that the unit offers no protection from liquid ingress. An IP60 rated device is dust-tight but not water resistant. In many cases this may indicate testing has been performed against dust ingress but not tested for water ingress.
