HEIDENHAIN AELB 382C Scanning Head For LB382C Grating Ruler

Technical Specifications

Model：AELB 382C Brand：HEIDENHAIN Product Type: Incremental sealed linear encoder scanning unit, matched with LB382C scale housing

Module Feature

Function: HEIDENHAIN AELB 382C is optical scanning read head specially designed for LB382C series sealed linear grating ruler. It captures optical signal from steel scale tape and converts into 1Vpp sine/cosine incremental measuring signals. It adopts distance-coded reference mark, which can establish datum point after single traverse. The scanning head can slide inside the encoder housing, suitable for long-travel machine tool axis. Widely used on heavy horizontal boring mills, large gantry machining centers for X/Y/Z axis closed-loop position feedback.

Measuring principle: Incremental optical interferential scanning Output Signal: 1 Vpp sine/cosine incremental signals Reference mark: Distance-coded reference marks Grating period: 40μm Onboard components: Optical scanning chip, PCB circuit, metal housing, 14-pin flange connector

LED indicators: Not equipped on scanning head

Hardware self-diagnosisSignal amplitude test, reference mark signal inspection, optical window contamination check

Programming softwareHEIDENHAIN diagnostic software for signal waveform monitoring and amplitude analysis

Electrical ParametersSupply voltage: 5VDC ±5% Power consumption: ≤200mA

Mechanical & StructureMounting: Fixed on machine slide carriage, moving together with axis Protection class: IP64 when assembled inside LB382C housing

EnvironmentalOperating temperature: 0℃ ~ +50℃ Ambient humidity: 5~85% non-condensing Certification: CE Status: HEIDENHAIN heavy-duty long travel linear encoder scanning head

System compatibilityCompatibility description: AELB382C matches HEIDENHAIN LB382C linear scale, compatible with HEIDENHAIN EXE interpolation units and CNC systems supporting 1Vpp input. Suitable for Fives Giddings & Lewis PIC900 CNC heavy boring mill linear axis.

FunctionFunction description: AELB 382C is scanning unit manufactured by HEIDENHAIN. It reads the grating on steel measuring tape and outputs high quality sinusoidal signals for high interpolation resolution. Distance-coded reference marks shorten homing travel for long axis. Compact scanning block structure can resist cutting fluid and workshop dust when installed inside sealed LB382C housing. It is core measuring spare for long stroke closed-loop control of heavy CNC boring mills.

InstallationInstallation steps: Follow lockout/tagout safety procedure before installation. Cut off all system power. Install scanning head on machine carriage, align optical gap with scale tape according to mounting tolerance. Insert scanning head into LB382C housing, connect 14-pin signal cable. Adjust mounting offset, lock fixing screws. Restore power, run signal amplitude test and reference mark detection.

InterfaceInterface list: 14-pin flange socket, 5V power and 1Vpp measuring signal terminals, no LED indicators for AELB 382C.

DiagnosticTroubleshooting: No measuring signal: Check 5V power supply, connector pin contact and optical window dirt. Reference mark missing: Incorrect gap or scale tape damage. Signal amplitude fluctuation: Vibration, oil contamination on optical surface or misalignment.
