Product Advantages and Features
1.Advanced light source technology
It adopts laser-like PinPoint LED light source technology, which produces bright and clear light spots, enabling more accurate detection. For example, the "Ji Liu" series photoelectric switches can be easily aligned and debugged by virtue of this technology. Some models, such as the WTB2S-2 blue light sensor, can penetrate the surface of dark solar wafers, and the V-shaped lens of WT2-S can accurately identify transparent glass or reflective metal surfaces with errors controlled at the micrometer level.
2.Strong anti-interference capability
Equipped with the new-generation SIRIC ASIC chip, it can effectively suppress various outdoor and indoor ambient light as well as electromagnetic interference, ensuring stable operation even in complex industrial environments. Some models of transmitters are featured with a second LED light, which can effectively suppress background light interference. They also have an anti-crosstalk function, making them suitable for through-beam and retro-reflective switches.
3.Diverse types of detectable objects
With the SIRIC® application-specific integrated circuit, it can identify objects of various types and characteristics. Whether they are transparent or dark, small or fast-moving, porous or shiny, all can be reliably detected.
4.Rich enclosure and operation options
There are various enclosure forms ranging from mini to compact types, which are compatible with different machine models. In addition, multiple connection and operation options are provided, facilitating installation on different devices.
5.Easy adjustment
Equipped with large adjustment knobs, such as the "Ji Liu" series, it allows for quick adjustment of sensitivity and sensing distance. There is also an adjustable potentiometer at the rear, which enables switching between light and dark modes, reducing installation time.

Product Application Scope
SICK photoelectric switches are widely used in various industries such as logistics, automobile manufacturing, automated production lines, and food processing.
nautomated production lines, SICK photoelectric switches can be used to detect the position of workpieces and count them. For example, diffuse reflection photoelectric switches can detect the arrival of workpieces on the conveyor belt and trigger subsequent processing procedures. Through-beam photoelectric switches can also be used to count workpieces, tally the production quantity, and facilitate production management and quality control.
Product Description
Workpiece positioning | When the conveyor belt delivers the workpiece to the processing station, the diffuse reflection photoelectric switch detects the workpiece (the reflected light triggers a signal), sends an "in-place" command to the PLC, and the PLC controls the robotic arm to start grabbing. |
Counting statistics | Through-beam photoelectric switches are installed on both sides of the conveyor belt. Each time a workpiece passes through, the light beam is blocked once, and the switch outputs a pulse signal. The PLC accumulates the number of pulses to realize production quantity statistics |
Anomaly detection | If a workpiece is stuck in the production line (fails to pass the detection point within the preset time), the photoelectric switch will continuously output a "signal present" or "no signal", triggering the alarm system to prevent equipment damage. |
