Industrial Applications

1. High-Speed Bottling Line Counting

On a beverage bottling line, the sensor is mounted to detect and count bottles as they move rapidly along a conveyor before capping. The application requires precise counting at high speeds and must withstand frequent cleaning cycles.

Problem Solved

The sensor's 1ms response time ensures no bottle is missed, even at high conveyor speeds. Its IP67 rating allows it to operate reliably despite regular high-pressure washdowns with cleaning agents, preventing downtime due to sensor failure.

2. PCB Presence Verification in Assembly Machine

Inside an automated electronics assembly machine, the sensor verifies that a PCB is correctly positioned in its fixture before the component placement (pick-and-place) sequence begins.

Problem Solved

The adjustable 20-300mm sensing range allows for precise tuning to detect the thin edge of the PCB without being triggered by machine parts in the background. The compact body (11.2x20x31mm) fits within the cramped confines of the machine, and the PNP output interfaces directly with the machine's standard PLC controller.

3. Package Detection on Sorting Conveyor

In a logistics facility, this sensor is used to detect the presence of packages of various sizes on a conveyor belt to trigger a downstream diverter arm for sorting.

Problem Solved

The sensor's adjustable background suppression is critical for reliably detecting packages of different colors and reflectivity while ignoring the conveyor belt just behind them. The IP67 rating ensures longevity in a potentially dusty warehouse environment, and the 12-24 VDC power requirement is standard for industrial control systems.
