Through Beam Reflective Photoelectric Sensor for Alarm G17

Photoelectric sensor is a device that converts optical signal into electrical signal. Its working principle is based on photoelectric effect. Photoelectric effect refers to the phenomenon that when light shines on some substances, the electrons of the substances absorb the energy of photons and the corresponding electric effect occurs

Through Beam Reflective Photoelectric Sensor for Alarm G17

Through-beam bype photoelectric switch is designed that via the light beam between opposite-mounted transmitter and receiver, the object passing through these two devices will interrupt the light beam and start the receiver.

Diffuse reflection type photoelectric switch integrates the transmitter and the reciver. Light reflected by the photoelectric switch is reflected back to the receiver by the detected object.

Retroreflective type photoelectric switch also integrates the transmitter  and the receiver, Its difference from other models is that reflecotr is used to relfect light to the photoelectric switch. Though the object between the photoelectric switch and reflector can reflect the light, it is much less  efficient than the reflector so as to cut down reflected light.
