Industrial Applications

1. Conveyor Belt Object Detection in Packaging Plants

This sensor can be mounted above a conveyor belt to reliably detect the presence or absence of packages, boxes, or products moving along. Its diffuse mode allows it to sense objects of varying colors and materials (e.g., cardboard, plastic, metal) without the need for a retroreflector. The adjustable detection range up to 600 mm provides flexibility for different belt widths and object heights.

Problem Solved

Ensures accurate counting, sorting, and proper positioning of diverse items on an assembly line, preventing production errors and jams, especially where objects lack uniform reflective properties.

2. Door/Gate Position Sensing in Industrial Machinery

Utilized to detect the open or closed state of safety guards, access doors, or movable components on industrial machinery. Its robust IP67 metallic housing protects it from dust, liquids, and mechanical impacts common in manufacturing environments. The wide operating temperature range (-40 to 60°C) ensures reliable performance in varied factory conditions.

Problem Solved

Enhances operator safety by confirming guard closure before machine operation and provides critical feedback for automated processes, contributing to regulatory compliance and machine uptime.

3. Level Control in Non-Contact Granular Material Bins

Positioned to detect the high or low level of granular materials (e.g., plastic pellets, grains, sand) in opaque bins or hoppers without making physical contact. The diffuse mode sensing is effective for detecting bulk materials, and the 600 mm range allows for flexible mounting above the fill line. Its compact M18 size permits installation in confined spaces.

Problem Solved

Automates the replenishment or discharge processes of bins, preventing overfilling or running empty, thereby optimizing material flow and minimizing human intervention in material handling systems.
