Application circuit
● Stains on the Window Can Impact Detection Performance
● Lens Material and Impact Avoidance
The lens is crafted from a delicate material called polyethylene. Applying pressure or force to the lens can lead to deformation and damage, resulting in malfunction and reduced performance. It is important to be cautious and prevent such occurrences.
● Static Electricity Precautions
Failure to discharge static electricity of ±200V or higher can lead to damage. Therefore, it is crucial to be mindful during operation and refrain from direct contact with the terminal using bare hands.
● Soldering Guidelines
When soldering a wire, ensure that the soldering iron does not exceed a temperature of 350 ° C and complete the soldering process within 3 seconds. Soldering through a solder bath may lead to performance degradation, so it is best to avoid this method.
● Sensor Cleaning Warning
Avoid cleaning the sensor to prevent cleaning liquid from seeping into the lens, which can result in performance deterioration.
● Shielded Wires for Cable Wiring
When utilizing cable wiring, it is recommended to use shielded wires to minimize interference and maintain optimal performance.
