Industrial Applications

1. Conveyor System Object Detection

Detects the presence and position of parcels, totes, or manufactured goods on industrial conveyor lines, providing automated routing and sorting triggers.

Problem Solved

Eliminates physical contact switches by reliably sensing items up to 2,000 mm away. The IP67-rated ABS housing withstands dusty or wet industrial environments.

2. Automated Gate and Barrier Control

Senses approaching vehicles or pedestrians to actuate automatic doors, boom barriers, and high-speed industrial roller doors.

Problem Solved

Simplifies installation through a universal 24-240V AC/DC supply and an isolated SPDT relay output, seamlessly integrating with existing door and gate controllers without auxiliary power supplies.
