Through Beam Photoelectric Sensor

Through beam photoelectric sensors are controlled by converting changes in light intensity into changes in electrical signals. In general, photoelectric sensors consist of three parts, which are: transmitter, receiver, and detection circuit. The transmitter aims at the target to emit a beam of light, which generally comes from semiconductor light sources, light-emitting diodes (LEDs), laser diodes, and infrared-emitting diodes. The beam emits continuously or changes the pulse width. The receiver consists of a photodiode, a phototransistor, and a photocell. In front of the receiver, optical components such as lenses and apertures are installed. Behind it is the detection circuit, which can filter out effective signals and apply them.

Built-in amplifier, resistant to sunlight interference

Through Beam Photoelectric Sensor (red light source, detection distance up to 10m) products are equipped with filters to prevent mutua! interference and can be used to resist sunlight;

Diffuse reflection products have a sensing distance of 300mm, built-in high-performance chips, and stable performance;



Improved the consistency between the optical axis and the mechanical axis

The deviation between the optical axis and the mechanical axis is controlled within +2.5. lt only needs to be installed in conjunction with the mechanical axis to achieve high-precision alignment with the optical axis. Through-beam and mirror-reflective types achieve longer detection distances.


Even if the wiring is wrong, the sensor can be protected

Equipped with output reverse polarity protection function (add reverse polarity protection diodes to the output line)
