BLTouch Auto Bed Leveling Sensor for Ender 3 / 3S / 3 V2 / CR-10

BLTouch Automatic Bed Leveling Sensor – Perfect First Layer Every Time

Say goodbye to tedious manual bed leveling. This BLTouch Auto Bed Leveling Sensor precisely measures the inclination of your print bed surface and automatically compensates the Z-axis height during printing — so you get a flawless first layer even on a slightly uneven platform.

Featuring progressively designed solenoids and a touch-probe sensor in a compact, lightweight body, this sensor integrates high precision into a simple structure. At just 50g, it won't add noticeable weight to your print head carriage.

Made in Mainland China.
