Photoelectric sensors according to the detection method can be opposed type, retro-reflective type, diffused type and BGS diffused type products
Opposed sensor: by blocking the beam between the transmitter and the receiver to detect non-transparent objects, strong stability, long detection distance
Retro-reflective sensor: by blocking the light beam between the sensor and the reflector to detect the object, can achieve transparent body detection
Diffused sensor: The sensor beam is reflected back to the sensor through the occlusion of the measured object to detect the presence or absence of the object. Conventional diffused is affected by the color of the measured object, while BGS diffused is less affected by the color of the measured object
