High Performance SMA Female-N male RG400 Coal Safety Wire (RF20022) Product details
1. Product Overview
The SMA Female-N male RG400 cable, model number RF20022, is a coal safety certified cable designed for special safety environments such as coal mines. It is manufactured in strict compliance with relevant safety standards to ensure safe and stable operation in dangerous environments such as potentially explosive gases, and provides a reliable connection for signal transmission between various types of coal mine communication, monitoring and other equipment.
2. Product specifications
(1) Interface type
One end is SMA Female (SMA female head) and the other end is N male (N type male head). The SMA interface is small and compact, and is often used in RF equipment with high space requirements. The N-type interface is robust and has good electrical performance, suitable for harsh industrial environments, and the combination of the two meets the needs of diverse equipment connections.
(2) Cable type
RG400 cables are used. RG400 is a high performance RF coaxial cable with low loss and wide application range of high frequencies. In the high-frequency signal transmission, it can effectively reduce signal attenuation, ensure the accuracy and stability of signal transmission, and can support a variety of frequency band signal transmission to meet the requirements of complex communication systems in coal mines.
(3) Cable length
Line length 3000mm, the length design not only provides a certain degree of wiring flexibility, to facilitate the connection between the equipment when there is a proper distance, but also will not cause excessive signal loss or wiring clutter due to too long, suitable for a variety of equipment layout scenarios in coal mines.
3. Product features
(1) Coal safety certification
Passed the coal safety certification, with excellent explosion-proof, flame retardant and other characteristics. Its outer sheath is made of special flame retardant materials, which can effectively prevent fire hazards caused by the cable's own heat or external fire source, and at the same time, it can prevent external dangerous gas explosion caused by internal electric spark in the structural design, and escort the safety of coal mine production.
(2) Low loss transmission
The characteristics of the RG400 cable determine that the loss during signal transmission is extremely low. Whether it is a wireless communication system, gas monitoring system or personnel positioning system used in coal mines, it can ensure efficient and stable signal transmission, reduce signal distortion and attenuation, and ensure the quality of communication between equipment.
(3) Strong durability
The outer sheath of the cable has good wear resistance and corrosion resistance, and can withstand the friction, collision, and erosion of moisture and corrosive gas in the complex environment of the coal mine. At the same time, the interface part is specially treated to have good vibration resistance and connection stability, even when the equipment is frequently shaken or pulled by external forces, it can ensure that the connection is reliable and not easy to loose.
Iv. Application scenarios
(1) Coal mine communication system
It can be used to connect the wireless base station, repeater and other equipment in the coal mine to ensure the stable transmission of voice and data communication, and achieve smooth communication between the well and the underground staff.
(2) Safety monitoring system
Connect gas sensors, carbon monoxide sensors and other environmental monitoring equipment and data acquisition devices to ensure that the monitoring data is accurately transmitted to the monitoring center, timely feedback of downhole environmental parameters, and provide data support for safe production.
(3) Personnel positioning system
In the coal mine personnel positioning system, it is used to connect the positioning base station and related communication equipment, ensure the reliable transmission of personnel location information, facilitate the real-time grasp of the dynamics of underground personnel, and improve the efficiency of emergency rescue and safety management.
5. Product advantages
(1) Professional adaptation
Designed and manufactured for the special needs of the coal mining industry, from the interface type to the cable performance, are highly adapted to the common equipment in the coal mine, without additional conversion equipment, reducing the use cost and failure risk.
(2) Reliable quality
Strict production process and quality control system to ensure that every cable is in line with high standards. After a variety of environmental simulation tests and practical application verification, the performance is stable and reliable, long service life, reduce later maintenance and replacement costs.
(3) Security
The coal safety certification gives it the safety of use in the dangerous environment of coal mine, reduces the possibility of safety accidents from the source, and provides a strong guarantee for the safety of coal mine production.
