PL08N 3D Printer Auto Bed Leveling Sensor, Inductive NPN Proximity Switch 8mm Detection, Easy Install

Auto Leveling Position Sensor PL08N for 3D Printer Overview The PL08N auto leveling position sensor adds automatic bed leveling capability to compatible selfassembly 3D printers. It reduces the need for manual bed adjustments and helps achieve more consistent first layers when used with a metal heated bed. Key benefits Enables auto leveling upgrade on supported DIY 3D printers, reducing manual calibration time and improving print consistency. Compact size and simple mounting make installation straightforward. NPN open output and wide input voltage range provide broad compatibility with many controller boards that accept NPN sensors. Main specifications Model: PL08N Item type: Leveling Module Output type: NPN Output condition: Open Test material: Metal only (the printer heat bed must be metal) Effective sensing distance: up to 8 mm Operating voltage: DC 4 to 30 V Package size: 7.5 x 7.5 x 1.8 cm Package weight: 37 g What is included 1 Auto Level Sensor PL08N 2 screws for mounting Compatibility and installation notes Designed for 3D printers that support an auto leveling sensor upgrade. Verify that your printer firmware and controller board accept an NPN open output sensor before installation. The sensor detects metal surfaces. It will not function correctly on nonmetal beds or beds with a nonmetal surface coating. Ensure the sensing distance and mounting position match your printer configuration to avoid false triggers. Compare the sensor voltage range and output type to your printer parameters to confirm compatibility. Practical use scenarios Upgrading a selfassembly 3D printer to automatic bed leveling when the controller supports NPN sensors. Replacing a faulty inductive or proximity leveling sensor on a metal heated bed. Prototyping or testing different bed heights and offsets during setup, taking advantage of the sensor s compact footprint. Additional notes Actual item color may vary slightly due to monitor and lighting differences. Allow small variations in measurements because of manual measurement.
