Industrial Applications

1. Conveyor Line Object Detection

Utilizing the CX-493 on a packaging conveyor line to detect the presence or absence of boxes. The sensor is mounted on one side of the conveyor, with the RF-230 reflector on the other side.

Problem Solved

The sensor's long 5m range and fast 1ms response time ensure that boxes of various sizes are reliably detected, even on wide or fast-moving conveyors, preventing jams and ensuring accurate counts for downstream sorting and packaging equipment.

2. Automated Gate and Door Control

Implementing the CX-493 as a safety or opening sensor for industrial automated gates, garage doors, or cleanroom access points. The sensor beam spans the entryway.

Problem Solved

The IP67 rating ensures reliable operation in outdoor or washdown environments, common for exterior gates. The selectable Light-ON/Dark-ON modes allow for flexible integration, either detecting a vehicle to trigger opening or sensing an obstruction to prevent closing, enhancing safety and automation.

3. Material Level Sensing in Hoppers

Mounting the CX-493 sensor near the top of a small to medium-sized material hopper to detect when the contents (e.g., plastic pellets, grain) have reached a 'full' level.

Problem Solved

The sensor's PBT housing and IP67 rating protect it from dust and potential non-corrosive material residue inside the hopper. Its 5m range is sufficient for most hopper widths, providing a simple, non-contact method to signal a PLC or indicator light to stop the filling process, preventing overfills and material waste.
