Frequently Asked Questions
What is the operating principle of this photoelectric sensor?
The operating principle of this sensor is based on retro-reflective technology, which uses a reflector to return the light beam emitted by the device back to the receiver. This allows for the detection of objects within its range.
Can this sensor be used in outdoor applications?
While the sensor has a robust IP65 protection rating, making it suitable for use in various environments, it's important to consider the specific conditions of outdoor use, such as extreme temperatures, direct sunlight, and potential physical obstructions that could affect its performance.
What type of light does the sensor emit?
The sensor emits visible red light, which is used for the detection of objects when they interrupt the light beam between the sensor and the reflector.
What are the dimensions of the sensor?
The dimensions of the sensor are 17 mm in width, 75 mm in height, and 32.5 mm in depth, making it a compact solution for various applications.
What is the maximum sensing range of the sensor?
The maximum sensing range of the sensor is up to 7 meters, with a typical operational range of up to 5 meters, depending on the reflector used and environmental conditions.
