M12/L=60mm Hall effect magnetic proximity sensor - NPN/PNP (all polarity)
✨Features
Product Introduction
The M12 Long-Body Magnetic Sensor (Connector Type) is engineered for automated systems where installation space and maintenance speed are critical. With a total length of 60mm, it offers a longer reach than standard M12 sensors, allowing it to pass through thicker machine walls or mounting blocks.
This sensor detects magnetic fields up to 10mm away (Omnipolar N/S) and supports versatile output configurations including NPN, PNP, and NO+NC. By utilizing a standard 4-pin M12 connector instead of a fixed cable, it minimizes downtime during maintenance, making it an ideal solution for modular conveyor systems, automotive jigs, and packaging machinery.

FAQ
Q：What is the main advantage of this connector model over the cable version?
A：Maintenance Speed. If a cable-type sensor is damaged, you must unroute the cable all the way back to the control cabinet to replace it. With this Connector Type, you simply unscrew the cable from the sensor body and screw it onto the new sensor. It takes seconds instead of minutes or hours.
Q：The total length is 60mm, but the thread is 41mm. What does this mean?
A：The sensor has a threaded section of 41mm at the front for mounting nuts. The remaining 19mm at the back is a smooth section that houses the M12 connector interface. This design ensures there is enough room to grip the connector plug without the mounting nuts getting in the way.
Q：Does this use a standard pin configuration?
A：Yes, it follows the IEC 61076-2-101 standard for M12 A-coded connectors:
Pin 1: Brown (+V)
Pin 2: White (Output 2 / NC)
Pin 3: Blue (0V / GND)
Pin 4: Black (Output 1 / NO)
