E3F-DS70 Infrared Detection Optical switch Sensor for Assembly line counting

Industrial Automation and Assembly Line Inspection
In the field of industrial automation, it can reliably determine if components are in place, sensitively detect missing manuals, accessories, or small bags during the packaging process, and accurately identify empty bottles or low liquid levels on the bottling line.

Positioning and Arrival Detection
Diffuse reflective photoelectric switches can accurately detect when a product moves to a specific station on the conveyor (such as coding, labeling, or sorting points), thereby triggering subsequent actions.

Non-contact Measurement of Object Contours and Heights
In automated stacking systems for cartons, boards, plastic pallets, and other materials, multiple diffuse reflective switches set at different heights can monitor the number of layers or the height of the stack in real time.

Safety Protection and Door Control
In areas involving dangerous equipment like rotating, cutting, or stamping machinery, diffuse reflective photoelectric switches are installed on door frames or cover edges to ensure guards are properly closed, providing an important safety barrier for operators. Additionally, in internal factory passages or logistics warehouse entrances, diffuse reflective switches are commonly used to detect the approach of people or vehicles, enabling automatic door opening or closing. ...

1. Single-sided installation: Only one sensor needs to be installed on the detection side, unlike through-beam sensors that require a separate reflector or receiver on the opposite side, making wiring more convenient.
2. Limited detection distance: Since it relies on the intensity of reflected light from the object's surface, the effective detection distance is relatively short, usually ranging from a few centimeters to a few meters, depending on the object's color, surface material, and sensor performance.
3.Strongly affected by object characteristics:
Color: Light-colored, highly reflective objects (such as white or mirrored surfaces) can be detected from a longer distance; dark, light-absorbing objects (such as black or dark gray) can only be detected from a shorter distance, and may even be undetectable.
Material: Smooth surfaces reflect light better, while rough surfaces scatter light and result in poorer detection.
Shape and angle: Flat surfaces work best, while curved or inclined surfaces may affect the path of reflected light.
Easy to install and adjust: However, care must be taken to avoid interference from background objects. ...
