How Many ‘‘U’’s Of 19-Inch Chassis are Most Commonly Used

19-inch is the size of most engineering-grade equipment panels, so 19 inch rack chassis  can meet a wide range of chassis; however, the most commonly used ones are 4U 19-inch chassis.

Knowledge of "U"

The installation height of the equipment in the 19in server rack is represented by a special unit "U", which specifically refers to the size of the effective space in the rack mount chassis, 1U=44.45mm. 4U means 4 cells, which is four times the thickness of the 1U chassis, which is more reliable in terms of protection.

The  4u server rack  enclosure has the basic advantages of ordinary standard chassis: good protection, extrusion resistance, corrosion resistance, good heat dissipation, anti-vibration, etc.

In addition, 4u server chassis, as a kind of industrial control chassis, is more widely used with its own unique performance:

Advantages of 4u rackmount：

①The use environment of industrial control chassis is relatively harsh. The basic advantages of the above-mentioned ordinary chassis have a significant improvement on the 4 u rack. 

②Having good scalability and stability is one of the main advantages of the 4u server rack. In a relatively harsh environment, the 4u wall mount rack enclosure is a good choice, which can effectively protect the host and form a better relationship with the outside world. protection.

③ For places with many unfavorable factors such as noise and dust, a 4u server chassis can also be used. The main board is divided into two parts, the bottom board and the CPU card.

Yonggucase C series 4U rackmount case makes the 19 inch case commonly used, practical and durable.

The new all-aluminum intelligent 19-inch standard industrial chassis is composed of front and rear panels, left and right side panels, and upper and lower cover panels. The whole machine is made of 6063-T5 extruded aluminum alloy profiles. Black, silver and white chassis are waiting for you to buy in stock, and anodized multi-color customization is waiting for you to choose. High-efficiency heat dissipation hole design, humanized fixed port, opening at any position, and delicate wire drawing process.

The 4U 19-inch rack sever chassis interprets the commonly used choice with its powerful strength.
