 LMF38 Series Inductive Prox Switch Introduction:

  • Our LMF38 sereis sensors is a bigger size round shape proximity sensor switch, it is a unshielded round shape sensor, diameter is 80mm.
  • Its installation method is screw fixed, easy to install, maximum sensing distance is 40mm.
  • PNP, NPN outputs are available, if the output is PNP, the signal is positive, so the load should be connected between the black wire and blue wire, models are LMF38-3040PA or LMF38-3040PB or LFM38-3040PC. On the contrary, if NPN, the load should be wired between brown wire and black wire, modes are  LMF38-3040NA or LMF38-3040NB or LFM38-3040NC.
  • This LMF38 series inductive prox switch is made by high quality ABS resin, and inner space is filled with epoxy resin, makes it IP65 rating.
  • This sensor is designed to detecting the metallic objects, such as stainless steel, iron, aluminum, lead etc..
  • More information about the proximity sensor, please see this article.


Wiring Diagram

The proximtiy sensor wiring diagrams can be divided into 3 kinds according to output difference, 2 wire wiring digram(sensor, load and power supply are connected in series), 3 wire proximtiy sensor wiring diagram(NPN or PNP, output is NO or NC) and 4 wire wiring diagram(NPN type or PNP type, output NO+NC), please see the below wiring diagrams:
