The technical features that a good photocell should have:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Detection Distance:<\/strong> It should be effective up to 0 \u2013 4 meters.<\/li>\n\n\n\n<li><strong>Detection Sensitivity:<\/strong> It should be able to detect even small objects of 1-2 cm size.<\/li>\n\n\n\n<li><strong>Number of Beam:<\/strong> Models range from 24 to 174 light beams. The higher the number of beams, the higher the level of security.<\/li>\n\n\n\n<li><strong>Supply Voltage:<\/strong> It is usually between 12 and 24 V DC.<\/li>\n\n\n\n<li><strong>Protection Class (IP):<\/strong> It should offer IP54 \u2013 IP65 level protection against dust, moisture and impacts.<\/li>\n\n\n\n<li><strong>Operating Temperature:<\/strong> It should be able to operate safely between -20\u00b0C and +65\u00b0C.<\/li>\n\n\n\n<li><strong>Standards:<\/strong> Must comply with CE, EN81-20 and EN81-50 standards.<\/li>\n<\/ul>\n\n\n\n<p>These features make the photocell useful not only in daily use but also <strong>in industrial and heavy-traffic elevators<\/strong> ensures trouble-free operation.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Advantages of Photocells<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Maximum Security<\/h3>\n\n\n\n<p>The biggest advantage of photocells is that they can cause problems when the door is closing. <strong>to prevent jamming accidents<\/strong>This ensures safe use for children, the elderly and people with limited mobility.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2.
