The first is to have high flame retardancy. We all know that the flame retardant performance of the cable is very important. The cable that fully ensures the safety and fire protection requirements, the cable is not easy to burn and ignite, and can prevent the expansion of the flame. The second is h... read more
Selection criteria for cable reels One of the selection criteria for cable reels-super strong ability to resist external forces The cable reel is greatly affected by external forces such as the environment, so the ability to resist external forces (and the material of the cable reel) is an important... read more
1.86 type switch: The most common switch socket has a square appearance, with a size of 86mm×86mm. This type of switch is often called the 86 type switch. The 86 type is an international standard. Many developed countries are equipped with the 86 type. The most commonly used switch in engineering an... read more
Delay switch The delay switch is a kind of switch that uses the electronic component relay to be installed in the switch, and the delay switch circuit. Delay switches are divided into voice control delay switches, light control delay switches, touch delay switches, etc. The principle of the time-del... read more
Switching power supply is a kind of power supply that uses modern power electronics technology to control the time ratio of switching on and off to maintain a stable output voltage. Switching power supplies are generally composed of pulse width modulation (PWM) control ICs and MOSFETs. Compared with... read more
The working principle of photoelectric switch After the modulated pulse generated by the oscillation circuit passes through the reflection circuit, the light pulse is radiated from the luminous tube GL. When the measured object enters the range of the light receiver, the reflected light pulse enters... read more
