Se as placas de entrada do seu PLC suportarem apenas entradas de transistor NPN, voc\u00ea dever\u00e1 usar um sensor de proximidade NPN. Por outro lado, se as placas de entrada do PLC suportarem apenas entradas de transistor PNP, voc\u00ea dever\u00e1 optar por um sensor de proximidade PNP. O uso do tipo errado de sensor de proximidade pode fazer com que o CLP n\u00e3o funcione corretamente.<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><b>Considera\u00e7\u00f5es sobre a fia\u00e7\u00e3o:<\/b><span style=\"font-weight: 400;\"> Os sistemas NPN geralmente compartilham uma conex\u00e3o de aterramento comum. Os sistemas PNP geralmente compartilham uma conex\u00e3o positiva comum. Em sistemas grandes, manter uma abordagem de fia\u00e7\u00e3o consistente (todos PNP ou todos NPN) pode simplificar a instala\u00e7\u00e3o. Portanto, se o seu sistema for projetado com fia\u00e7\u00e3o PNP, tente usar um sensor PNP e, se for um sistema NPN, use um sensor NPN.<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><b>Imunidade a ru\u00eddos<\/b><span style=\"font-weight: 400;\">: Sensores NPN: Geralmente t\u00eam melhor imunidade a ru\u00eddos em ambientes eletricamente ruidosos.
