Industrial Applications

1. Automated Conveyor Pallet Detection

In heavy-duty logistics and automated storage facilities, detecting large pallets across expansive conveyor lines requires a long-range, environmentally immune sensor.

Problem Solved

The 22-meter sensing range and robust retro-reflective dual-lens system ensure accurate detection of large objects, overcoming vibrations and ambient warehouse lighting interference.

2. Outdoor Access Gate and Barrier Monitoring

Monitoring vehicle or personnel access at outdoor security gates requires a sensor capable of handling universal voltage inputs and extreme weather conditions.

Problem Solved

With a 20-250V AC/DC input and a fully sealed IP67 zinc die-cast housing, the sensor integrates directly into older or diverse gate controllers while surviving freezing -40°C outdoor conditions.
