Feature: 1. Intelligent leveling, intelligent compensation of Z‑axis height, making leveling more intelligent and simple 2. This 3D printer sensor have accurate measurement with small error, which bring high leveling accuracy 3. The product equipped with patch positioning sensor, therefore get higher consistency 4. 3D Touch automatic leveling sensor is a device that uses Hall effect to achieve leveling, which possess high accuracy and fast respond 5. The position of the point can be obtained by touching the point on the hot bed, and printing can be achieved even when the platform is uneven Specification: Item Type: 3D Touch Auto Bed Leveling Voltage: 5V Current: 15ma Maximum (1 value) Current: 300mA Shell Material: PC Shell Color: White translucent Connection: 3pin: Green (-, GND) Red (+5V) Orange (signal line) 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).
