3D Touch Auto Bed Leveling Sensor for 3D Printers

3D Touch Auto Bed Leveling Sensor is a high-precision automatic bed leveling sensor designed to improve first-layer adhesion and printing accuracy. It uses Hall-effect sensing technology with a retractable probe to measure multiple points across the print bed and automatically compensates for surface irregularities. Compatible with most open-source 3D printers and BLTouch-supported firmware, it provides reliable, repeatable, and accurate bed leveling for consistent print quality.Features:Automatic bed leveling for improved first-layer accuracy.High-precision Hall-effect sensing technology.Excellent probe repeatability for consistent printing.Compatible with glass, PEI, metal, magnetic, wood, and BuildTak print surfaces.Supports Marlin, Klipper, Repetier, and Smoothieware firmware.Compatible with most BLTouch-supported controller boards.Self-test function with LED status indication.Standard 5-wire interface for easy installation.Low power consumption.Fast and reliable probing operation.Compact and lightweight design.Suitable for Ender, CR Series, Prusa, Anycubic, Anet, BIQU, Voron, and other compatible FDM 3D printers.Specifications:ParameterValueProduct TypeAutomatic Bed Leveling SensorSensor TechnologyHall Effect Sensor with SolenoidOperating Voltage4.8V – 5.1V DCLogic Voltage3.3V / 5V CompatibleTypical Operating Current15mAPeak Current300mAProbe Repeatability≤0.005mmMeasurement Accuracy±0.005mmProbe Stroke5.6 – 6.6mmTrigger MethodMechanical Retractable ProbeProbe OutputOpen Drain (Logic Free) / 5V LogicMaximum Output Voltage (VDS)5VMaximum Output Current (ID)300mAControl SignalPWM Servo SignalServo Signal Range650µs – 2190µsInterface5-Pin ConnectorWiring3-Pin Servo + 2-Pin Z-MinServo PinoutBrown (GND), Red (+5V), Orange (Control)Z-Min PinoutBlack (GND), White (Signal)LED IndicatorSelf-Test / Status LEDHousing MaterialPolycarbonate (PC)Probe Pin MaterialEngineering PlasticPCB FinishLead-Free SMTCable Length150mm (Probe Cable)Extension Cable LengthApproximately 1m (Version Dependent)Mounting TypeStandard BLTouch / 3D Touch MountFirmware SupportMarlin, Klipper, Repetier, SmoothiewareMainboard CompatibilityRAMPS, SKR, MKS, Duet, Creality, BTT and other BLTouch-compatible boardsPrinter CompatibilityEnder Series, CR Series, Prusa i3, Voron, Anycubic, Anet, BIQU and other FDM 3D PrintersSupported Bed MaterialsGlass, PEI, Magnetic Sheet, Steel, Aluminum, BuildTak, Wood and Composite SurfacesFunctionsAuto Bed Leveling, Self-Test, Alarm Release, Touch Mode, Probe Deploy & RetractOperating Temperature-10°C to +60°CWeightApproximately 10gAlso Check These Out:Hall Magnetic Sensor ModuleFlame Sensor ModuleShock Sensor ModuleReed SwitchPackage Includes:1 × 3D Touch Auto Bed Leveling Sensor for 3D Printers
