M12/L=50mm Hall effect magnetic proximity sensor - NPN/PNP (all polarity)
✨Features
Product Introduction
The M12 Long-Body Magnetic Proximity Sensor is a versatile position detection solution designed for flexibility in installation. Its key differentiator is the 50mm Full Thread design, allowing the sensor to be secured at any point along its body length, which is ideal for applications requiring precise gap adjustment.
Operating on a standard 10-30 VDC supply, it detects magnetic fields (N or S pole) up to 10mm away. It offers a comprehensive range of output options (NPN/PNP, NO/NC/Complementary) to suit any control system. With its IP67 rating and rugged Nickel-Plated Brass construction, it delivers consistent performance in automated assembly, packaging machinery, and pneumatic systems.

FAQ
Q：Why would I choose this "Full Thread" model over a standard one?
A：Standard sensors often have a smooth section at the back or a "cap." A Full Thread model allows you to screw the mounting nuts all the way from the front to the back. This is extremely useful if you are mounting the sensor through a very thick plate or if you need a wide range of adjustment to fine-tune the distance to the magnet.
Q：What is the benefit of the "NO+NC" (Complementary) output option?
A：The NO+NC option provides two output signals on a 4-wire cable. One wire signals when the magnet is present (NO), and the other signals when it is absent (NC). This is often used for safety redundancy (checking for wire breaks) or for controllers that require dual-channel verification.
Q：Can this sensor detect a magnet through a steel plate?
A：No. Steel (ferrous material) absorbs magnetic fields. The sensor can detect a magnet through aluminum, brass, plastic, or wood, but if you place a steel sheet between the sensor and the magnet, the steel will block the magnetic field, and the sensor will not trigger.
