M8 Hall Effect Magnetic Proximity Sensor, PNP/NPN, NO/NC

A magnetic proximity sensor is a non-contact position detection switch that converts magnetic signals into electrical signals. It uses a magnetic field as the medium, allowing magnetic or related physical quantities to trigger the sensor without mechanical contact. This design prevents wear, avoids damage to the detected object and enables fast response.

Magnetic proximity switches commonly offer three output states: normally open, normally closed, and latched. Output forms include NPN and PNP types. Wiring can be configured as two-wire, three-wire, four-wire, or five-wire, and supports both AC and DC systems.

Yes. It is recommended to connect a current-limiting resistor and a protection diode in series. These components prevent damage if the power supply polarity is reversed. Although the sensor will not burn out under reverse polarity, it will not function normally until the wiring is corrected.
