The 555 Timer is a mid-scale integrated device that combines analog and digital functions. Generally known as 555, which is made by bipolar process, it is called 7555 in CMOS process. In addition to single timer, there is a corresponding dual timer 556/7556.555. The power supply voltage range is wide, which can be 4.5V~ Operating at 16V, the 7555 can operate from 3 to 18V with an output drive current of approximately 200mA, so its output is compatible with TTL, CMOS or analog circuit levels.
The function of the 555 timer is mainly determined by two comparators. The output voltages of the two comparators control the state of the RS flip-flops and discharge tubes. Apply voltage between the power supply and ground. When the 5 pin is left floating, the voltage at the non-inverting input of the voltage comparator C1 is 2VCC /3, and the voltage at the inverting input of C2 is VCC /3. If the voltage of the input terminal TR is triggered If it is less than VCC /3, the output of comparator C2 is 0, which can set the RS flip-flop to 1 to make the output terminal OUT=1. If the voltage of the threshold input terminal TH is greater than 2VCC/3, and the voltage of the TR terminal is greater than VCC /3, Then the output of C1 is 0, and the output of C2 is 1. The RS flip-flop can be set to 0 to make the output 0 level.

HD Slip Ring

HD Slip Ring is an electromechanical device. It allows the transmission of power and signals from a stationary to a rotating structure. It consists of an electrically conductive rotating ring, with one or more stationary contacts. They are called "stations" or "spokes". Electrical signals (power and/or data) are transmitted through the slip ring. This is done by means of brushes that make contact with the ring.


It is typically used where there is a need to rotate one object relative to another. Especially for passing power and/or signals from the stationary object to the rotating object.


Regarding it's application in conjunction with other equipment, we'll need high-quality production. Oubaibo uses components imported from the United States and high-frequency signal processing. Which has the characteristics of small size, lightweight, good insulation performance, stable transmission, and so on. Its unique design makes it an ideal choice for many applications.
