M18 DC 3/4-Wire Inductive Sensors

M18 DC 3/4-wire inductive sensors are general-purpose proximity sensors with an M18x1 threaded cylindrical housing that run on direct current and detect metal targets without contact. They are used on conveyors, packaging machines and machine tools for jobs such as part presence, mechanical position and detecting revolutions on a gear. This category includes Lanbao and Isıso branded models with sensing distances such as 5 mm, 8 mm, 12 mm and 20 mm; the output is PNP or NPN, NO, NC or four-wire NO+NC. Choose the sensing distance, flush or non-flush head, output type, switching frequency and cable or M12 connector connection according to the passing distance of the target and the PLC input card. The product data lists switching frequencies of 400 Hz, 800 Hz and 1 kHz; if counting is done over a gear or cam, the passing frequency of the target must stay below this value. An M18 inductive sensor does not replace a photoelectric sensor made in the same M18 housing; it detects only a metal target, and only from a distance of a few millimeters.

How to choose M18 DC 3/4-Wire Inductive Sensors

M18 DC 3/4-wire inductive sensors are general-purpose proximity sensors with an M18x1 threaded cylindrical housing that run on direct current and detect metal targets without contact. They are used on conveyors, packaging machines and machine tools for jobs such as part presence, mechanical position and detecting revolutions on a gear.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
