M30 DC 3/4-Wire Inductive Sensors

M30 DC 3/4-wire inductive sensors are DC-powered sensors with an M30x1.5 threaded cylindrical housing that, thanks to a wide sensing face, detect metal from a longer distance than smaller housings. They are used to detect position and presence in conveyor, door, crane and heavy machinery applications where the target cannot be brought close to the sensor. This category includes Lanbao and Isıso branded models with sensing distances such as 10 mm, 15 mm, 22 mm and 30 mm, with a 2 m cable or M12 connector. Choose the sensing distance, flush or non-flush head, NPN or PNP, NO, NC or NO+NC output and connection type according to the target distance and the PLC input card. Switching frequency generally drops as the housing gets bigger, and the product data for this category lists 300 Hz and 500 Hz; an M12 or M18 housing is more suitable for small targets and tight mounting locations. An M30 inductive sensor should not be confused with a capacitive sensor made in the same M30 housing; an inductive sensor detects only metal, and a capacitive sensor is needed for plastic, liquids and granules.

How to choose M30 DC 3/4-Wire Inductive Sensors

M30 DC 3/4-wire inductive sensors are DC-powered sensors with an M30x1.5 threaded cylindrical housing that, thanks to a wide sensing face, detect metal from a longer distance than smaller housings. They are used to detect position and presence in conveyor, door, crane and heavy machinery applications where the target cannot be brought close to the sensor.

  • 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.
