Vershoven 06.47 Headset WHA with spiral cord content_copy

The Vershoven WHA, manufacturer's part number 06.47, is a robust industrial headset specifically designed for use in demanding environments. It features a dynamic microphone and a coiled cord connection, making it suitable for industrial communication systems, particularly in areas with high ambient noise, such as machine rooms or cold storage facilities. The headset enables clear conversations even in ambient noise up to 115 dB (A), as the microphone compensates for external noise and optimizes voice transmission.

Applications
The WHA is designed for industrial applications where extreme environmental conditions such as high temperatures, cold, or high humidity prevail. It is suitable for use in cold storage facilities, ship engine rooms, or other production environments where robust and reliable communication is required. The IP54 protection rating ensures a certain level of protection against dust and splashing water, making it suitable for outdoor use or in humid indoor environments.

Features and Specifications in Detail
The headset includes a dynamic microphone with an impedance of 230 Ohm and a sensitivity of -63 dB V/Pa at 1 kHz. The microphone noise reduction is 12 dB at 1 kHz, meaning the microphone effectively attenuates interference noise in the frequency range around 1 kHz. The earpiece principle is also dynamic, with an impedance of 150 Ohm at 1 mW/1 kHz and a rated power handling of 50 mW. The earpiece noise reduction is 27 dB, which makes speech reproduction clearer and less susceptible to interference. The earcups are made of impact-resistant plastic, enhancing mechanical durability.

Technology Explained Simply
The dynamic microphone operates without external power supply and directly converts sound waves into electrical signals. Noise reduction is achieved through the microphone’s special design, which attenuates interference noise in the frequency range of 100–5,000 Hz. The earpiece is also dynamically constructed and can reproduce frequencies from 150 Hz to 12 kHz, which is sufficient for clear voice transmission. The coiled cord allows for flexible connection to the telephone without restricting the user’s mobility.

Compatibility and Accessories
The WHA is designed for use with industrial telephones compatible with coiled cord connections. No specific accessories are mentioned in the sources; however, it can be used with standard industrial telephones that offer the appropriate interface for coiled cords.

Installation and Mounting
Mounting is done by connecting the headset to the industrial telephone via the coiled cord. No special installation instructions or tools are mentioned in the sources. Installation is accomplished by simply connecting the headset to the telephone.

Operational Advantages
The WHA offers high mechanical robustness and is designed for extreme environmental conditions. The operating temperature range is from -30 °C to +70 °C, and the storage temperature range is from -40 °C to +80 °C. The permissible relative humidity is below 93 %, enabling use in humid environments. The noise reduction and clear voice transmission ensure reliable communication even in noisy surroundings.
