The first covers solids. The second covers water. In the three codes listed above, the first digit is the same, and it&#8217;s the second digit that takes effect.<\/p>\n<figure class=\"wp-block-table\">\n<table class=\"has-fixed-layout\">\n<tbody>\n<tr>\n<td><strong>Avalia\u00e7\u00e3o<\/strong><\/td>\n<td><strong>Water test<\/strong><\/td>\n<td><strong>In practice<\/strong><\/td>\n<\/tr>\n<tr>\n<td>IP66<\/td>\n<td>12.5mm nozzle, about 100 L\/min, at least 3 minutes<\/td>\n<td>Powerful jets, heavy rain, wash-down<\/td>\n<\/tr>\n<tr>\n<td>IP67<\/td>\n<td>Temporary immersion, up to 1m for 30 minutes<\/td>\n<td>Flooding or standing water that drains away<\/td>\n<\/tr>\n<tr>\n<td>IP68<\/td>\n<td>Continuous immersion under conditions agreed between manufacturer and user<\/td>\n<td>Submerged use; the depth and duration are not fixed by the standard<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<p>Two points are easy to miss:<\/p>\n<ul>\n<li>IP66 and IP67 test different things. Jets are not immersion. A product can pass one and not the other, so IP67 is not automatically &quot;better&quot; than IP66 for a pole-top light sensor photocell switch.<\/li>\n<li>IP68 has no single meaning. The test conditions are set by agreement, so one manufacturer&#8217;s IP68 may not match another&#8217;s.<\/li>\n<\/ul>\n<h2>Why Isn&#8217;t an IP Rating Enough for a Coastal Site?<\/h2>\n<p><img decoding=\"async\" src=\"https:\/\/leaditop.com\/wp-content\/uploads\/2026\/11\/seaside-dock-night-lighting.webp\" alt=\"Wooden pier at dusk lit by dock lights under an orange sunset sky\" \/><\/p>\n<p>An IP rating describes water and dust ingress at the time of testing. It does not describe how the product ages.<\/p>\n<p>IP testing does not cover:<\/p>\n<h4>Salt spray and chloride exposure<\/h4>\n<p>Various elements react differently in different environments. This calls for a different corrosion test.<\/p>\n<h4>Galvanic corrosion<\/h4>\n<p>This is when two dissimilar metals corrode more quickly because of salt moisture between them \u2013 for example, brass pins with a steel pole bracket.<\/p>\n<h4>UV aging<\/h4>\n<p>Plastics become brittle in the presence of salt and high temperatures.<\/p>\n<h4>Seal fatigue<\/h4>\n<p>Gaskets compress, stiffen, and crack after repeated exposure to temperature changes.<\/p>\n<p>To be more explicit, a light sensor switch that meets IP66 in a new state may be found wanting in its third year if the material used in it was not suited for the coastal environment.<\/p>\n<h2>Which Photoelectric Sensor IP Rating Fits Which Coastal Location?<\/h2>\n<p>Exposure varies a lot, even within one project.<\/p>\n<figure class=\"wp-block-table\">\n<table class=\"has-fixed-layout\">\n<tbody>\n<tr>\n<td><strong>Localiza\u00e7\u00e3o<\/strong><\/td>\n<td><strong>Typical exposure<\/strong><\/td>\n<td><strong>Rating to consider<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Inland road, 5+ km from coast<\/td>\n<td>Rain, occasional wind-blown salt<\/td>\n<td>IP65 or IP66<\/td>\n<\/tr>\n<tr>\n<td>Seafront promenade, coastal highway<\/td>\n<td>Salt mist, driven rain, high humidity<\/td>\n<td>IP66 with coastal-grade materials<\/td>\n<\/tr>\n<tr>\n<td>Port, harbour, quay, wash-down area<\/td>\n<td>Direct spray, jet cleaning, salt crust<\/td>\n<td>IP66 minimum; IP67 where flooding is possible<\/td>\n<\/tr>\n<tr>\n<td>Low-lying flood-prone site<\/td>\n<td>Occasional temporary submersion<\/td>\n<td>IP67<\/td>\n<\/tr>\n<tr>\n<td>Permanent submersion<\/td>\n<td>Continuous immersion<\/td>\n<td>Not a normal photocontrol application<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<p>Practical note<\/p>\n<p>With regard to most pole-top and wall-mounting light photocell sensors, the luminaire and control are installed above flood level.

IP66 evaluates sprays and jets. IP68 evaluates immersion according to mutually agreed conditions.

Ask for the test duration and the result, not only a pass statement.<\/p>\n<h3>Is IP67 worth specifying?<\/h3>\n<p>It can be critical where temporary flooding and standing water are possible. Where it is not, IP66 usually suffices.<\/p>\n<h3>Do Lead-Top photocontrols come in IP68?<\/h3>\n<p>No. The listed options range between IP65 and IP67.
