A switching power supply uses modern power electronics technology to regulate the on-off time ratio of the switching transistor, ensuring a stable output voltage. A typical switching power supply consists of a pulse width modulation (PWM) control IC and MOSFETs. Compared to linear power supplies, both types see increasing efficiency with higher output power, but their growth rates differ. At a certain power level, the cost of a linear power supply becomes higher than that of a switching one—this is known as the cost reversal point. As power electronics technology advances, switching power supply technology continues to evolve. This reversal point is shifting toward lower power levels, opening up new opportunities for development in this field.
The new generation of photoelectric switches integrates circuit technology and SMT components, offering intelligent features such as delay, signal broadening, external synchronization, interference resistance, high reliability, stable performance, and self-diagnosis. These advanced photoelectric switches are active detection systems using pulse modulation. They use cold light sources like infrared, red, green, and blue light, enabling contactless, fast, and damage-free control of solids, liquids, transparent objects, black bodies, soft materials, and smoke. Unlike traditional mechanical or proximity switches, which suffer from slow response, low precision, and limited detection capabilities, these new photoelectric switches offer compact size, multiple functions, long lifespan, high accuracy, fast response, extended detection range, and strong resistance to light and electrical interference.
Photoelectric switches are widely used in various applications. They can operate stably even in high ambient lighting conditions. However, it's important to avoid pointing the sensor’s optical axis directly at strong light sources like sunlight or incandescent bulbs. If this isn't possible, a visor or light-shielded tube can be added around the sensor. The MGK series of new photoelectric switches include automatic anti-interference features, eliminating concerns about cross-talk. For the HGK series of on-beam infrared switches, when installed in multiple groups close together, adjacent units may interfere. To prevent this, you can stagger the emitter and receiver positions, increase the spacing between groups, or use different frequency models for better isolation.
