Description

technical field [0001] The invention relates to a photoelectric sensor, in particular to a dual-band photoelectric sensor for collecting two different optical signals for feedback. Background technique [0002] A photoelectric sensor is a sensor that uses a photoelectric device as a conversion element. It can be used to detect non-electric quantities that directly cause changes in light quantity, such as light intensity, illuminance, radiation temperature measurement, gas composition analysis, etc., and can also be used to detect other non-electric quantities that can be converted into light quantity changes, such as part diameter, surface roughness, strain , Displacement, vibration, velocity, acceleration, as well as the shape of the object, the recognition of the working state, etc. Photoelectric sensors have the characteristics of non-contact, fast response, and reliable performance, so they are widely used in industrial automation devices and robots. However, the curre...
