The ZF-J series encapsulated explosion-proof relay features a stainless steel explosion-proof housing designed according to GB/T3836 standards (Exmb Ⅰ Mb). It is specifically built for use in environments with explosive gas mixtures and must be operated within an explosion-proof enclosure. This relay ensures secure operation in hazardous environments.

The YBZ-240 explosion-proof battery monitoring instrument (hereinafter referred to as the instrument) is designed for underground coal mines. With an explosion-proof rating of Exdb I Mb, it is mainly used for monitoring the voltage, remaining capacity, electrode-to-ground insulation resistance, and motor-to-ground insulation resistance of battery locomotives and other battery packs. When the remaining capacity or insulation resistance falls below the specified value, the instrument issues an alarm. It adopts intelligent design, allowing data acquisition and parameter configuration through an upper-level computer. The product complies with Q/YZY006 "YBZ Series Explosion-Proof Battery Monitoring Instrument" standard.

The KXB series mining explosion-proof display controller is designed for monitoring and controlling parameters such as pressure, temperature, level, flow, and speed in mining equipment. It supports input signals like 4-20mA, frequency pulses, and CAN/RS485. The controller features a 3.3-inch OLED display and explosion-proof stainless steel housing, meeting GB/T3836 standards (Exdb Ⅰ Mb), suitable for both underground and surface mining.

The KWB explosion-proof micro switch features a casing made of stainless steel or H62 copper, designed to meet GB/T3836 standards (Exdb Ⅱ CT6Gb/Exdb Ⅰ Mb). It is used in hazardous environments where water, dust, and explosion resistance are essential. The switch operates by compressing or releasing the push rod to activate or release the switch, outputting an effective switch signal. It is widely used in oil, chemical, and power industries to control subsequent equipment for automated operations.
