M12/L=45mm Hall effect magnetic proximity sensor - NPN/PNP (all polarity)
✨Features
Product Introduction
The M12 Magnetic Proximity Sensor (Connector Type) is designed for efficient maintenance and high-speed automation. By utilizing a standard M12 4-pin connector, this sensor supports "Plug and Play" functionality, making it the preferred choice for modular machine designs and areas where cables may need frequent replacement.
The sensor detects standard NdFeB magnets up to 10mm away through non-ferrous materials (aluminum, plastic). It features Omnipolar technology (N/S pole independent) and offers flexible output logic (NPN/PNP, NO/NC). Encased in a rugged Nickel-Plated Brass body with IP67 protection, it ensures reliable operation in harsh factory environments while remaining lightweight (28g).

FAQ
Q：Does this sensor come with a cable?
A：No, this is a Connector Type sensor. It has an integrated M12 plug on the back. You will need to purchase a separate M12 mating cable (female connector) to connect it to your system. This allows you to choose the exact cable length and material (PVC or PUR) you need.
Q：What is the standard pinout for this connector?
A：It follows the industrial standard (IEC 61076-2-101):
Pin 1 (Brown): +VDC (10-30V)
Pin 3 (Blue): 0V (GND)
Pin 4 (Black): Output 1 (Usually NO)
Pin 2 (White): Output 2 (Usually NC or not connected, depending on model)
Q：How does Nickel-Plated Brass compare to Stainless Steel?
A：Nickel-Plated Brass is the industry standard for general automation. It is strong and resists rust well. Stainless Steel is typically used in food processing or extremely corrosive chemical environments. For most factory conveyors, packaging machines, and assembly lines, Nickel-Plated Brass is the most cost-effective and sufficient choice.
