M12 DC 3/4-Wire Inductive Sensors

M12 DC 3/4-wire inductive sensors are DC-powered proximity sensors with an M12x1 threaded cylindrical housing that detect metal objects without contact. They are used to report the position of metal parts to the PLC at pneumatic cylinder and slide strokes, on small machine elements and in narrow brackets. Three-wire models give a single NO or NC output, and four-wire models give NO and NC outputs together. This category includes Lanbao and Isıso branded models with sensing distances such as 2 mm, 4 mm, 6 mm and 8 mm, with a 2 m cable or M12 connector; on products that specify the housing material, it is nickel-plated brass. Choose the flush or non-flush head, sensing distance, NPN or PNP output, NO or NC contact and switching frequency according to the mounting location and the PLC input card. On the same M12 housing, non-flush head models offer a longer distance but are not suitable for flush mounting in metal. The M12 in the category name is the thread size of the housing and should not be confused with the M12 connector; the same connector is also used on M8, M18 and M30 housing sensors.

How to choose M12 DC 3/4-Wire Inductive Sensors

M12 DC 3/4-wire inductive sensors are DC-powered proximity sensors with an M12x1 threaded cylindrical housing that detect metal objects without contact. They are used to report the position of metal parts to the PLC at pneumatic cylinder and slide strokes, on small machine elements and in narrow brackets.

  • 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.
