Feature:1. Intelligent leveling, intelligent compensation of Z‑axis height, making leveling more intelligent and simple2. This 3D printer sensor have accurate measurement with small error, which bring high leveling accuracy3. The product equipped with patch positioning sensor, therefore get higher consistency4. 3D Touch automatic leveling sensor is a device that uses Hall effect to achieve leveling, which possess high accuracy and fast respond5. 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 unevenSpec:Item Type: 3D Touch Auto Bed LevelingVoltage: 5VCurrent: 15maMaximum (1 value) Current: 300mAShell Material: PCShell Color: White translucentConnection:3pin: Green (-, GND)Red (+5V)Orange (signal line)2pin: Black (-, GND)White (Zmin)Size: Approx. 11.54mm / 0.5inApprox. 5.77mm / 0.2inApprox. 9mm / 0.4inApprox. 18mm / 0.7inApprox. 2 ~ 3.2mm / 0.08 ~ 0.13inApprox. 26mm / 1inApprox. 9.7mm / 0.4inApprox. 7.7mm / 0.3inApprox. 36mm / 1.4inApprox. 26.3mm / 1inApprox. 19.5mm / 0.8inApprox. 5.5mm / 0.2inMaximum: Approx. 11mm / 0.4in(±1mm)Approx. 13mm / 0.5inAbove approx.15mm / 0.6inApprox. 8.2mm / 0.3in(±0.2mm)Package List:1 x Sensor1 x Wound Terminal1 x Line2 x M3 Nut2 x M3 Screw2 x Terminal
