Particularly suitable for interior spaces such as offices, hallways, technical rooms or sanitary facilities, the sensor impresses with its high precision - even with the smallest movements.<\/p>\n<h2>Flat design \u2013 powerfully installed<\/h2>\n<p>Thanks to its compact installation depth of just 66 mm and an installation diameter of 63-66 mm, the NOA is ideal for suspended ceilings. The sturdy built-in springs ensure a secure hold without additional fastening material. Its unobtrusive design makes it the perfect choice for stylish room concepts.<\/p>\n<h2>360\u00b0 capture with high precision thanks to 24 GHz HF technology<\/h2>\n<p>Inside works a <strong>24GHz CW radar<\/strong>, which is available in royalty-free <strong>ISM band<\/strong> sends. This high frequency technology enables a <strong>extremely accurate motion detection<\/strong> even with minimal movement - ideal for areas where people sit or stand for long periods of time. The detection range covers a radius of up to 3 m (\u00d8 6 m), even at a mounting height of 2 to 4 m.<\/p>\n<h2>Flexible settings for every application<\/h2>\n<p>You can adjust three central parameters on the device:<\/p>\n<ul>\n<li><strong>LUX:<\/strong> Light sensitivity from 3 to 2000 lux \u2013 can be optimized for day and night operation<\/li>\n<li><strong>SENS:<\/strong> Infinitely adjustable sensitivity \u2013 for precise detection<\/li>\n<li><strong>TIME:<\/strong> Follow-up time between 10 seconds and 12 minutes \u2013 adjustable as required<\/li>\n<\/ul>\n<h2>Installation made easy \u2013 for old buildings and new buildings<\/h2>\n<p>The connection is made simply via luster terminals (L, N, L\u2032). The sensor is suitable for both individual installation and for <strong>Master-slave cabling<\/strong> for larger light groups. With a maximum switching power of 1000 W (or 2000 W with ohmic load) it is also suitable for powerful lights.<\/p>\n<div style=\"padding: 10px; border-radius: 5px; border: 2px solid rgb(255, 213, 79); border-image: none; background-color: rgb(255, 248, 225);\"><strong>A notice:<\/strong> One <strong>ohmic load<\/strong> lies e.g.\u202fThis is the case, for example, with classic light bulbs - they produce light immediately without additional electronics. <strong>LED bulbs<\/strong> however, are among the <strong>inductive loads<\/strong>, as they contain electronic ballasts. These can cause briefly high currents when switched on. This is why LED lamps have a lower switching capacity than incandescent bulbs.<\/div>\n<div style=\"padding: 10px; border-radius: 5px; border: 2px solid rgb(33, 150, 243); border-image: none; background-color: rgb(227, 242, 253);\"><strong>Protection class:<\/strong> The sensor head that is visible to the outside is with <strong>IP65<\/strong> certified and therefore dust-tight and protected from water jets \u2013 ideal for damp rooms. The concealed interior is included <strong>IP20<\/strong> classified and intended for dry areas. A suitable one is included in delivery <strong>sealing washer<\/strong> included, which must be inserted between the sensor head and the ceiling during installation to ensure protection class IP65.<\/div>\n<h2>Systematic energy saving<\/h2>\n<p>Thanks to automatic detection, lighting is only activated when it is really needed - this saves energy, extends the life of your lamps and reduces electricity costs in the long term.<\/p>\n<div style=\"padding: 10px; border-radius: 5px; border: 2px solid rgb(179, 229, 180); border-image: none; background-color: rgb(230, 255,
