Product infomation

Parameters

The photoelectric switch is controlled by converting the change of light intensity into the change of electrical signal. Photoelectric sensor in general, there are three parts, they are divided into: transmitter, receiver and detection circuit. The transmitter fires a beam of light at the target, usually from semiconductor light sources, light-emitting diodes (leds) and laser diodes. The beam is emitted without interruption, or the pulse width varies. The receiver consists of a photodiode or a phototriode. In front of the receiver, optical elements such as a lens and an aperture are installed. Behind it is the detection circuit, which filters out the effective signal and applies the signal. In addition, there are emission plates and optical fibers in the structural components of the photoelectric sensor. The triangular reflector is a solid reflector. It is composed of a small triangular cone reflecting material, which can accurately return the light beam from the reflecting plate, and has practical significance. It can vary the emission Angle from 0 to 25 in relation to the optical axis, so that the beam is almost from an emission line, after reflection, or return from the reflected ray. Optical fiber (also known as optical fiber lwl), which expands the use of photoelectric sensors, forming a special embedded transceiver device. It can be used in special environments to detect tiny objects. It can obtain satisfactory answers at very high external temperatures and in structurally restricted environments.
