The HSM-D dual-lock Cable Gland structure adopts a double protection design. One end of the product is designed to prevent detachment, ensuring that the cable will not come loose due to external forces. At the same time, the internal flameproof sealing ring adopts a displacement sealing design, greatly improving the sealing effect of the product and making it more suitable for use in areas with explosion risks. It allows non-armored cables to be directly inserted into flameproof enclosures, lamps, outlets, plugs, etc. Their structure makes them suitable for particularly challenging environments, such as marine environments or environments with frequent mechanical stress and impacts in heavy industries, while still ensuring normal production. They are equipped with a flameproof sealing ring to meet the explosion protection level Ex eb IIC Gb/s Ex tb IIIC Db and protection level IP66/68. This ensures that the cable sealing kit can meet the maximum performance, long-term reliability, and safety requirements. The product is widely used in control panels, instruments, lamps, mechanical equipment, trains, motors, engineering, and other fields.
