Si est\u00e1 buscando uno de estos sensores, primero deber\u00e1 diferenciar los tipos de transistores que existen para realizar un circuito. A partir de esta informaci\u00f3n tambi\u00e9n ser\u00e1 m\u00e1s sencillo elegir el mejor controlador l\u00f3gico programable. En esta ocasi\u00f3n nos enfocaremos en el sensor tipo <b>NPN<\/b>, debido a sus principales funciones para desarrollar sistemas digitales.<\/p>\n<p>Primeramente, definamos <b>qu\u00e9 es un transistor NPN. <\/b>Es un sensor con uni\u00f3n bipolar que brinda una corriente mayor del colector al emisor. Este tipo de sensor NPN tambi\u00e9n es conocido como BJT.<\/p>\n<p>Este transistor puede servir como un interruptor capaz de ser controlado de manera electr\u00f3nica, o como amplificador que brinda una ganancia variable. Para el caso de funcionar como amplificador, la corriente generada por el colector debe ser proporcional a la corriente base, multiplic\u00e1ndose por la beta del transistor.<\/p>\n<p>Otro de las aplicaciones de este tipo de transistor es como una base para desarrollar sistemas digitales; en otras palabras, esto se toma como base para crear tecnolog\u00eda. Es posible distinguirlo en la conmutaci\u00f3n, por las compuertas l\u00f3gicas que permiten crear sistemas embebidos que realizan funciones en tiempo real.<\/p>\n<h2><b>Caracter\u00edsticas de un transistor NPN<\/b><\/h2>\n<h3><b>Elementos de la estructura interna NPN<\/b><\/h3>\n<p>En cada una de las capas semiconductoras se encuentran tres regiones de conexi\u00f3n, los cuales son:<\/p>\n<ul>\n<li><b>Emisor<\/b>. Es el \u00e1rea por donde entra el flujo de corriente al transistor.<\/li>\n<li><b>Base<\/b>. En esta parte se modula el flujo de corriente que va entre el emisor y colector.<\/li>\n<li><b>Colector<\/b>. Zona por donde sale la corriente modulada.<\/li>\n<\/ul>\n<h3><b>Materiales sensor NPN<\/b><\/h3>\n<p>Para elaborar los materiales de este transistor se toma en cuenta que sean semiconductores.<\/p>\n<p>Las capas<b> N<\/b> se crean por el cristal Silicio con algunas impurezas, como el ars\u00e9nico, f\u00f3sforo, antimonio.<\/p>\n<p>La capa <b>P <\/b>es formada tambi\u00e9n con cristales de Silicio y utiliza impurezas como el boro.<\/p>\n<h2><b>Diferencia entre NPN y PNP<\/b><\/h2>\n<p>Estos dos tipos de transistores son de uniones bipolares, pero sus signos de voltaje son diferentes. Entonces, <a href=\"https:\/\/www.autycom.com\/cual-es-la-diferencia-entre-transistores-pnp-y-npn\/\"><b>\u00bfc\u00f3mo saber si un sensor es PNP o NPN?<\/b><\/a> Podr\u00e1 identificarlos por el tipo de aplicaciones que utilizan, o el tipo de corriente que las impulsa. Otra manera es por la forma en que se controla el flujo.<\/p>\n<p>Para dejarlo m\u00e1s claro, el transistor NPN se impulsa con una corriente positiva polarizada, la cual controla el flujo del Colector al Emisor. A diferencia del transistor PNP que requiere de una corriente negativa polarizada y el flujo va del Emisor al Colector.<\/p>\n<p>Si necesita m\u00e1s orientaci\u00f3n sobre transistores industriales, <a href=\"https:\/\/www.autycom.com\/contact\/\">cont\u00e1ctatenos aqu\u00ed<\/a> para brindarle m\u00e1s informaci\u00f3n.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Los transistores son dispositivos semiconductores de corriente, indispensables para la automatizaci\u00f3n industrial.
