Hall Effect Sensor | IP68 Magnetic Proximity Switch 15/20mm NPN/PNP

This small Hall effect magnetic sensor reliably detects magnetic fields without touching them. It's for position sensing. Its compact size and IP68 rating mean it works in tight spots and tough industrial settings. This remote nonpolar magnetic proximity sensor is a solid choice for automation projects. Features and Benefits - NPN and PNP models - Pick the right output for your control system. NPN switches the output to ground (sinking). PNP switches it to the positive voltage (sourcing). - NO or NC logic - Available as Normally Open (circuit closes when a magnet is there) or Normally Closed (circuit opens). This allows flexible system design. - IP68 rated enclosure - The sealed housing keeps out all dust. It can also be submerged in water. This means it works in dirty or wet conditions. - 3-wire 12-24V DC operation - This 3-wire Hall sensor connects easily to standard low-voltage industrial controls. It uses simple power, ground, and signal wiring. Applications - Pneumatic cylinder control - Detects when the piston reaches the end of its stroke in automated machines. - Rotational speed counting - Measures how fast a shaft spins by detecting magnets attached to it. - Access control - Senses if a door, gate, or safety guard is open or closed. This is for security or automation systems. What It Is This is an Effect Magnetic Sensor, also known as an IP68 Proximity Switch, designed for reliable object detection. It functions as a Hall Effect sensor, capable of detecting the presence of a magnetic field. With a robust IP68 protection rating, it is suitable for demanding industrial environments. The sensor operates on 12V DC or 24V DC power and features a 3-wire wiring configuration. It is available with either NPN or PNP output types, and can be configured for Normally Open (NO) or Normally Closed (NC) switching functions. Key Uses & Applications This proximity sensor is ideal for applications where non-contact detection of metallic objects is required. Common uses include position sensing in automated machinery, counting parts on a production line, and limit switching for moving components. Its IP68 rating makes it suitable for wet or dusty conditions, such as in manufacturing plants or outdoor equipment. The 15mm or 20mm diameter options allow for integration into various setups. It can be used to control electronics modules or as a reliable industrial sensor for automation tasks. How to Choose When selecting this proximity sensor, consider the required detection distance and the type of object to be sensed. While this is a magnetic sensor, other proximity sensors include optical sensors. For this specific product, choose between 12V DC or 24V DC to match your power supply. Determine if you need an NPN or PNP output and whether a Normally Open (NO) or Normally Closed (NC) switching function is appropriate for your control system. The 15mm or 20mm diameter should fit your mounting requirements. To test a proximity sensor, apply the correct voltage and observe its output state when an appropriate target is introduced and removed.
