KJJ660(BMining explosion-proof and intrinsically safe Gigabit ring network switches (hereinafter referred to as switches) are mainly used in underground coal mines for data transmission and exchange. They meet the needs of high flexibility and scalability in the application field, helping customers upgrade their Ethernet networks. Equipped with high flexibility and efficiency, they are suitable for any harsh application environments.

Explosion-proof switch structure
This product consists of four main parts: a gigabit or 10-gigabit switch, a backup battery, a charging/discharging board (with remote management capability), and a housing. Its dimensions are 735mm * 727mm * 868mm.
Explosion-proof 10Gigabit switches feature quick-opening structures and support 660V and 127V power inputs.
Switches support common mainstream brands such as Hirschmann, MOXA, Dongsan, Sanwang, Maiwei, etc., facilitating the construction of industrial Ethernet rings for mining applications, and support gigabit and 10-gigabit networking. Backup batteries support charging and discharging management, with a backup time exceeding 4 hours.
