Industrial Applications

1. Small Component Detection on PCBA Conveyors

In a printed circuit board assembly (PCBA) line, this sensor can be used to verify the presence of small electronic components before they enter a reflow oven. The application requires precise, non-contact detection in a confined space.

Problem Solved

The sensor's small spot beam and adjustable 2-50mm range allow it to accurately detect minute components without mistakenly sensing the PCB itself or adjacent parts. Its fast 1ms response time keeps pace with the conveyor belt speed, ensuring no component is missed.

2. Pharmaceutical Vial Counting and Positioning

A pharmaceutical packaging machine needs to accurately count and position small glass or plastic vials before they are filled and capped. The environment is clean but may involve washdowns, requiring a sealed sensor.

Problem Solved

The IP67 rating ensures the sensor withstands cleaning cycles without failure. The precise red LED spot can reliably detect the leading edge of each vial for accurate counting and positioning, and its selectable Light-On/Dark-On modes can be configured to ignore reflections from the shiny surfaces.

3. Web Break Detection in Printing Presses

In a high-speed printing press, a continuous sheet of paper (a web) runs through the machine. If the web tears, the machine must be stopped immediately to prevent jams and damage.

Problem Solved

The sensor is positioned to constantly see the paper web. Its fast 1ms response time allows it to immediately signal a break in the web to the machine's control system (PLC) via its NPN output. The sensor's immunity to interference and stable operation ensure it does not false-trigger from paper dust or vibrations.
