Photoelectric proximity switches made use of the photoelectric effect switch called photoelectric switch. The light emitting device according to a certain direction of the photovoltaic device installed in the same test head. When a reflective surface (detected object) approaching, the optoelectronic device receives the reflected light after the signal output, which can "sense" an object closer. Precautions edit general industrial production sites, usually chosen eddy proximity switch and capacitive proximity switches. Because the two proximity switches on the environment less demanding conditions. When the measured object is conductive objects or can be fixed on a metal object LB-0524PC 60mm, generally use eddy proximity switches, because of its high frequency response, anti-environmental interference performance, wide range of applications, the price is low. If the measured object is a non-metal (or metal), liquid height, height of powder, plastics, tobacco. Capacitive proximity switches should be used. This switchable low frequency response, but good stability. Installation should consider the impact of environmental factors. If the analyte for magnetic materials or to distinguish objects and moving it together and put magnets buried in the measured object, should use Hall proximity switch LB-M0824LB normally closed, its lowest price. Environmental conditions are good, no dust pollution occasions, photoelectric proximity switches can be used. Photoelectric proximity switches work when almost no shadow of the measured object. Therefore, the higher the fax machine, have been widely used in the tobacco machinery. In the anti-theft system LJ30A3-15-Z / BY, automatic doors usually pyroelectric proximity switches, ultrasonic proximity switches, microwave proximity switch. Sometimes in order to improve the reliability of identification, the several proximity switches are often used together. No matter what the choice of the proximity switch, should pay attention to the working voltage, load current, frequency response requirements of the indicators, detection distance.
