In recent years, there have been numerous accidents when using water heaters to bathe. In addition to the leakage of electric water heaters, explosions, and carbon monoxide poisoning caused by gas water heaters, the occurrence of hot water burns during the bathing process has also occurred from time to time. Recently, there have been many cases where the baby was burned while taking a bath because the water temperature was too high and the parents were careless.
With the advent of the fourth-generation water heaters, the safety hazards of traditional water heaters have been completely eliminated, becoming the most popular water heater in the market. First of all, from the aspect of energy saving, air-energy water heaters can save 75% energy than electric water heaters, and can save a lot of electricity expenses each year; from a safety point of view, air-energy water heaters will not be subject to electric shock and carbon monoxide poisoning due to separation of water and electricity and incombustible gas. risk. From the aspect of environmental protection and comfort, air-energy water heaters absorb heat from the air to produce hot water without any emissions, and do not cause any pollution to the environment. Moreover, the air temperature of the water heater can be constant, and the phenomenon of hot and cold will not occur. The water tank has a long holding time and can ensure hot water at any time and 24 hours a day. It is very comfortable.
According to the head of R&D of Hua Tiancheng, the top ten leading brand in the air energy industry, the air energy water heaters all adopt intelligent control and the water temperature is set freely. For example, the water temperature required for a baby shower is about 37-40 degrees. Using a traditional water heater to heat the baby to take a bath, all adults use their elbows to test the water temperature, and they feel that they can use it properly. But the baby's skin is not better than adults. Sometimes adults think that the water temperature is appropriate, but the baby can't stand it. The use of air energy water heaters can completely set the temperature of the hot water to the baby's most comfortable temperature, never worry about the risk of being burned.
The person in charge further introduced that although the water temperature of our high-temperature wall-hanging machine series developed for urban families can reach 80°C, the outlet water temperature is controlled freely according to the user's needs, and therefore the scalding event does not occur. In addition to 80 °C hot water can be diluted into more hot water required for bathing, but also play a role in high-temperature sterilization, giving the user a real five-star hot water enjoyment.
Coaxial Power D-Sub Solder Cup Contacts with Mixed or Full Layout
Transmit Radio Frequency Signals
The Coaxial D-Sub have like the Power D-Subr replaced the two rows in a Standard Density connector with a coaxial contact that take up about the same size as the two rows of signal contacts. The Coaxial D-Sub is exactly the same size as the Standard Density connector but instead of example 9 positions of signal pins it has 2 power contacts , or instead of 37 positions of signals it has 8 coaxial contacts.
The Impedance for the coaxial contacts are 50Ω or 75Ω
The Coaxial D-Sub with Mixed Layout mixes both coaxial contacts and signal contacts in the same connector. For example the same size as a 15 position Standard Density D-Sub you can have what we call a 7W2, which means there is 7 contacts where 2 of them are coaxial contacts, which means there are 5 signal contacts, so 5 signals and 2 coaxial. See the Layout in the Tech Specs on the bottom, there are a lot of combinations of the Mixed Layout alternative.
Antenk's Coaxial D-Sub connectors are available in 5 standard shell sizes with 23 multiple contact arrangements. These reliable, robust combination d-sub connectors allow a combination of signal and coaxial contacts in cable mount, vertical board mount & right angle board mount termination type variations.
