JSR-HF01-SMK-40 Series High Frequency Rotary Joint

JSR-HF01-SMK-40 is a single channel high-frequency slip ring. It can support 1 channel high frequency (up to 40GHz) transmission under 360 ° rotation and can be used in high and low temperature (- 55 ℃ ~ + 100 ℃). The two ends of the slip ring are connected with SMK type connectors, with stable signal transmission, ultra-low attenuation, and long service life. This product has been successfully applied to traditional artificial intelligence traffic control, missile defense radar technology, medical engineering, V-sat and satellite communication technology, TV camera system, or cable drum with sensitive cable wound.

Applied Projects



Radar, the radio detection and ranging, Radar uses radio to find targets and determine their spatial positions. Therefore, radar is also known as "radio positioning". Radar is an electronic device that uses electromagnetic waves to detect targets. Modern early warning radar, search and warning radar, guidance and command radar, gun aiming radar and other series of radars all need to rotate constantly to search for and locate targets. The company that can make the radar work normally owes a lot to the optical fiber slip ring. The optical fiber slip ring can ensure that the radar can transmit various electromagnetic signals normally while rotating 360 degrees so that the radar can quickly and accurately explore, locate and strike targets. JARCH's High-Frequency Rotary Joint & optical fiber slip ring is widely used in various radars due to its high transmission rate and is trusted by new and old customers.


Photoelectric Theodolite System

Through the electrical transformation of the optical theodolite, it can capture the target image and record the accurate angle measurement information in real-time. It can also obtain the accurate central axis offset of the target through the interpretation and processing of the target image after the event, and a more accurate angle measurement value can be obtained by superposition. The photoelectric theodolite transmits the signal to the computer through optical imaging, so as to achieve accurate positioning and capture the image of the target. In order to capture the target faster, modern photoelectric theodolites need to rotate quickly, and at the same time, they also transmit the captured image signal to the computer. Therefore,JARCH's High-Frequency Rotary Joint & optical fiber slip ring plays a very important role here.002

Fire control system

The fire control system is the equipment installed on aircraft, armored vehicles, warships, and other platforms. Its full name is fire command and control engineering. It is the general name of the equipment that controls automatic aiming and launching of shooting weapons. The modern fire control system can not be separated from the accurate calculation and rapid aiming of the computer. In order to efficiently and accurately lock the target and strike, all fire control systems are equipped with high-quality optical fiber slip rings. The high-quality optical fiber slip rings can ensure that the fire control system can accurately strike while capturing the target at high speed. The optical fiber slip rings produced by Jiachi can meet military standards and have been used in the control systems of various weapons for many times.003
