Weatherproof Electronic Sounders for Harsh Industrial and Marine Environments | Qlight

In demanding industrial environments where dust, water, and extreme weather are part of daily operations, having a reliable signaling system is not a luxury but a necessity. Qlight, a global leader in visual and audible signal devices, provides a strong lineup of weatherproof electronic sounders designed specifically for outdoor and heavy-duty use.

Why Weatherproof Sounders Matter?

In challenging environments such as mines, offshore platforms, and outdoor industrial sites, traditional sounders often fail due to exposure to dust, moisture, and extreme weather. These conditions can affect both reliability and performance, putting safety at risk. Qlight addresses this challenge with a range of weatherproof, high-decibel sounders specifically designed to operate in harsh conditions.

SANA Series

The SANA200, SANA400, and SANA700 are compact, high-decibel weatherproof air horns designed for reliable signaling in harsh marine and industrial environments. With a sound output of up to 130 dB and varying frequency ranges, these horns are ideal for alerting in factories, marine settings, and hazardous areas. The series supports both DC and AC voltages and is built with IP56-rated housing for outdoor and harsh-condition use.

• SANA200: Low-frequency tone (200–300 Hz) with a deep, resonant sound—ideal for long-range or heavy industrial use.
• SANA400: Mid-frequency tone (400–600 Hz)—balanced and versatile for general-purpose signaling.
• SANA700: High-frequency tone (700–800 Hz)—sharp and penetrating, suitable for noisy or compact workspaces.

QEB

• QEB is a robust solenoid valve box with explosion-proof protection rated Ex d IIC T6 and IP66, suitable for hazardous environments.
• Operates in -40°C to +60°C with DC 24V or AC 110V/220V options and features a standard Munsell 7.5BG 7/2 housing with optional explosion-proof cable gland.

SEWN50

• SEWN50 is a high-performance electronic sounder for vessels, steel plants, and outdoor use, offering up to 114dB with 4 different built-in tones or 5 user-defined voice messages.
• Built with durable aluminium housing, it features IP66 protection, CE compliance, adjustable volume, 1/2″PF cable entry, and operates from -30°C to +50°C. 

SHDN30

• SHDN30 is a dual-facing, weatherproof sounder designed for harsh industrial and marine settings, offering 4 different built-in tones or 5 user-defined voices with up to 114dB output ×2.
• Features a durable aluminium and PC housing, IP56 protection, internal volume control, 1/2″PF cable entry, and operates from -30°C to +50°C. 

SPNA

• SPNA is a high-performance explosion-proof sounder delivering up to 118dB, with 4 different built-in tones or 5 user-defined voice messages (110–115dB), volume adjustment, and support for alarms, warnings, melodies, and voice alerts.
• Built with a durable aluminium housing and STS316L protection cage, it features IP66 protection, 1/2″ NPT cable entry, operates from -40°C to +60°C (depending on certification), and is certified by IECEx, ATEX, NEPSI, KCs, CCC, CCS, and TS; standard housing color is Munsell No. 7.5BG 7/2.
