Banner LT3 Series | L-GAGE Laser Distance Sensor | 50m Range, TOF

Banner LT3 series laser distance sensors. Time-of-flight (TOF) technology, diffuse mode up to 5m, retroreflective up to 50m, analog (4-20mA/0-10V) & discrete outputs, IP67.

Product Overview

The Banner LT3 Series​ (also known as L-GAGE® LT3) is a family of laser distance measurement sensors​ utilizing time-of-flight (TOF)​ technology. These sensors are designed for precise position detection, level monitoring, and object gauging in industrial automation. The series includes both diffuse-mode​ models (0.3–5 m range) and retroreflective​ models (0.5–50 m range), offering a combination of analog (4-20 mA / 0-10 V)​ and discrete (NPN/PNP)​ outputs for flexible integration into control systems.

Key Features

• Long-Range Detection:​ Retroreflective models offer reliable sensing up to 50 meters, ideal for crane positioning and large-scale bin level detection.

• Dual Output Flexibility:​ Most models provide simultaneous analog​ (for distance value) and discrete​ (for threshold switching) outputs, reducing the need for multiple sensors.

• Easy Setup:​ TEACH-mode programming​ allows quick configuration of sensing windows and hysteresis via a front button or remote input, eliminating the need for potentiometers.

• Robust Industrial Design:​ IP67-rated​ housing withstands harsh environments, including dust, moisture, and washdown conditions.

Applications

• Material Handling:​ Pallet positioning, conveyor jam detection, and overhead crane collision avoidance.

• Level Monitoring:​ Bulk solid and liquid level measurement in silos, hoppers, and tanks.

• Machine Automation:​ Roll diameter measurement, web guiding, and robotic cell presence sensing.
