Frequently Asked Questions

Q What is the working voltage range for the BJX-24E explosion-proof buzzer?
The BJX-24E operates on a DC voltage range of 15V to 32V, making it compatible with a wide range of industrial power supplies commonly used in hazardous area installations.
Q What is the difference between the Stainless Steel and Aluminum Alloy versions of the BJX-24E?
The key differences lie in the body material, dimensions, and sound output. The Stainless Steel 304 + PC version produces >75 dB @ 1m and has a cylindrical form (⌀43mm × 70mm × 81mm), while the Aluminum Alloy version delivers a louder >80 dB @ 1m with a rectangular profile (L75mm × W48mm × H85.5mm).
Q What explosion-proof certification does the BJX-24E carry?
Both versions of the BJX-24E are certified to Ex d IIC T6 Gb, meaning they are suitable for use in Zone 1 and Zone 2 hazardous areas with flammable gases classified under Group IIC (including hydrogen), with a maximum surface temperature of T6 (85°C).
Q What are the installation connection types for each model variant?
The Stainless Steel version uses a G3/4" External Thread for conduit-style installation, while the Aluminum Alloy version connects via an M2.6 × 1.5 thread fitting, offering flexibility for different mounting environments.
Q In what environmental conditions can the BJX-24E be used?
The BJX-24E is rated for operation in temperatures from -10°C to +50°C, relative humidity of 10% to 95% RH (non-condensing), and atmospheric pressure between 86 and 106 kPa, suitable for a wide range of industrial outdoor and indoor environments.
Q Which material version should I choose for harsh outdoor environments?
For environments exposed to corrosion, moisture, or chemical contact, the Stainless Steel 304 + PC version offers superior corrosion resistance. If lightweight construction and higher acoustic output are priorities, the Aluminum Alloy version is the recommended choice with its louder 80 dB sound intensity.
