Function:1. Intelligent leveling, intelligent compensation of Z-axis height, making leveling more intelligent and simple2. This 3D printer sensor has accurate measurement with small error, providing high leveling accuracy3. The product is equipped with patch positioning sensor, providing higher consistency4. The 3D Touch automatic leveling sensor is a device that uses the Hall effect to achieve leveling, providing high accuracy and fast response5. The position of the point can be obtained by touching the point on the heated bed, and printing can be achieved even when the platform is uneven Specification: Item Type: 3D Touch Automatic Bed Leveling Voltage: 5V Current: 15ma Maximum (1 value) Current: 300mA Shell Material: PC Shell Color: White transparent Connection: 3pin: Green (-, GND) Red (+5V) Orange (signal wire) 2pin: Black (-, GND) White (Zmin) Size: Approx. 11.54mm / 0.5in Approx. 5.77mm / 0.2in Approx. 9mm / 0.4in Approx. 18mm / 0.7in Approx. 2 ~ 3.2mm / 0.08 ~ 0.13in Approx. 26mm / 1in Approx. 9.7mm / 0.4in Approx. 7.7mm / 0.3in Approx. 36mm / 1.4in Approx. 26.3mm / 1in Approx. 19.5mm / 0.8in Approx. 5.5mm / 0.2in Maximum: Approx. 11mm / 0.4in (1mm) Approx. 13mm / 0.5in Above approx. 15mm / 0.6in Approx. 8.2mm / 0.3in (0.2mm).
