Meskernel LDK-80 80m Visible Red Light Laser Sensor Distance Measurement Instruments Mini Distance Sensor Module

Overview

Meskernel LDK-80 is a Distance Measurement Instruments Mini Distance Sensor module using a visible red light laser for precise laser distance measurement. It delivers up to 80 m indoor range (dependent on target reflectivity), millimeter-level resolution, and compact dimensions suitable for integration in industrial and embedded applications.

Laser Distance Module is designed for precise measurement, which has high accuracy, fast measuring speed, easy to install and operate. The module is applicable to daily measurement, industrial measurement, warehouse monitoring, traffic investigation, and robots.

Specifications

Note

Measurement conditions

Under bad measure condition, like environment with strong light or the diffuse reflectance of measuring point over-high or low, the accuracy would have bigger amount of error: ±1 mm+50PPM.

Use of reflector

Under strong light or bad diffuse reflectance of target, please use a reflector.

Custom temperature range

Operating temperature -10 ~50 ℃ can be customized.

Fast mode frequency

8Hz only be activated when Fast continuous measuring mode is using.

Applications

Intelligent mechanical arm

Add high-precision distance transmission to the robot arm to accurately control the distance of the robot arm target.

Intelligent logistics

It can be used in intelligent logistics to ensure that goods are placed at a specified distance without human operation.

engineering surveying

Widely used in distance, area, volume measurement.

Security Monitoring

Can be used with Airport Security Monitoring and infrared-cameras.

Transfer belt

Measure whether there is cargo on the conveyor belt.
