M18 Capacitive Sensor

  • M18 sensors includes CM18-3005NA, CM18-3005NB, CM18-3005NC etc.,
  • Detection distance 5.0mm, 8.0mm, output can be PNP, NPN, NO, NC,
  • Good performance of anti-interference, has short-circuit protection and inverted connecting protection,
  • High on-off frequency, wide voltage range, IP67 protection grade.

M18 Capacitive Sensors Introduction:

  • M18 capacitive sensors here means their thread size is M18, that is a 18mm diameter sensor. Our model for these sensors is called CM18-XXX.
  • The default housings material of our these sensors is stainless steel, the other material is plastic. Different capacitive sensor housings prices will be different.
  • The sensing distance of our M18 capacitive sensor is 5.0mm for shielded ones, unshielded ones is 8.0mm. (More knowledge of the shielded and unshielded sensor differences, please read this article.)
  • It used to detect various kinds of objects detect any object (such as glass, metal, water, oil, paper etc.)without contact,
  • Widely used in many areas, such as  liquid level control and for sensing powdered or granulated material.


Wiring Diagram

The capacitive proximity sensor switch 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:
