In its most common version, a pair of photocells (emitter-receiver) transmits an infrared beam; if the beam is interrupted by an obstacle, the receiver stops receiving the signal and an automation is triggered, for example stopping the motor of an automatic door or activating an alarm.\r\n<h3 style=\"font-size: 1.15rem\">Basic components<\/h3>\r\n<ul>\r\n \t<li><strong>Emitter and receiver:<\/strong> elements that emit and detect the beam.<\/li>\r\n \t<li><strong>Filter or retroreflector:<\/strong> improves detection and prevents false signals from ambient light.<\/li>\r\n \t<li><strong>Power supply and cable:<\/strong> requires electrical connection and connection to the control panel.<\/li>\r\n \t<li><strong>Contact (NC\/NO):<\/strong> outputs for integration with the motor circuit.<\/li>\r\n<\/ul>\r\n<h2 style=\"font-size: 1.4rem\">Types of photoelectric sensors and photoelectric cells<\/h2>\r\nThere are reflective photoelectric cells, emitter-receiver types, and safety photoelectric cells. Some are adjustable, slim or modular; others include battery or solar panel for autonomous power supply. Industrial models reach distances of 15 m or 20 m according to specifications.\r\n\r\n<h2 style=\"font-size: 1.4rem\">Benefits of using photoelectric cells<\/h2>\r\n<ul>\r\n \t<li><strong>Increased safety:<\/strong> prevent crushing and accidents.<\/li>\r\n \t<li><strong>Energy efficiency:<\/strong> optimise the use of lighting.<\/li>\r\n \t<li><strong>Reliable automation:<\/strong> direct integration with motors and automation systems.<\/li>\r\n \t<li><strong>Durability:<\/strong> designed for outdoor use and demanding conditions.<\/li>\r\n<\/ul>\r\n<h2 style=\"font-size: 1.4rem\">Practical applications<\/h2>\r\n<h3 style=\"font-size: 1.15rem\">Outdoor and industrial lighting<\/h3>\r\nThey function as light sensors to switch on streetlights, panels or fa\u00e7ade lighting when ambient brightness decreases, avoiding unnecessary activations.\r\n<h3 style=\"font-size: 1.15rem\">Garage doors and automatic gates<\/h3>\r\nA pair of photoelectric sensors creates a safety barrier that stops or reverses the motor movement upon detecting an obstacle, being mandatory in many automatic systems.\r\n<h3 style=\"font-size: 1.15rem\">Access control and security<\/h3>\r\nThey are used to detect passage, activate alarms or coordinate automatic doors with other control systems.\r\n<h2 style=\"font-size: 1.4rem\">How to choose the right photoelectric sensor<\/h2>\r\n<ul>\r\n \t<li>Required range (15 m, 20 m or higher).<\/li>\r\n \t<li>Type of photoelectric sensor according to installation.<\/li>\r\n \t<li>Compatibility with motor and control panel.<\/li>\r\n \t<li>Protection for outdoor use.<\/li>\r\n \t<li>Available power supply type.<\/li>\r\n<\/ul>\r\n<h2 style=\"font-size: 1.4rem\">Installation and maintenance<\/h2>\r\nIt is essential to correctly align the emitter and receiver, protect the wiring, and periodically check that the beam is not obstructed by dirt or objects.\r\n<h2 style=\"font-size: 1.4rem\">Conclusion<\/h2>\r\nPhotoelectric sensors are a key solution in automation, lighting, and security. Choosing the right model improves safety, reduces energy consumption, and ensures reliable operation.\r\n\r\nFor technical advice and professional supply, contact <strong>Electr\u00f3nica Edimar<\/strong> and receive a personalised recommendation.","link":"https:\/\/electronicaedimar.com\/en\/tienda-electronica\/fotocelulas\/","name":"Photoelectric Sensors","slug":"fotocelulas","taxonomy":"product_cat","parent":0,"meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/electronicaedimar.com\/en\/wp-json\/wp\/v2\/product_cat\/60","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/electronicaedimar.com\/en\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/electronicaedimar.com\/en\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"wp:post_type":[{"href":"https:\/\/electronicaedimar.com\/en\/wp-json\/wp\/v2\/product?product_cat=60"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
