The A24 industrial telephone from Vershoven is a weatherproof device designed for use in dusty and humid environments. It serves as a station telephone and terminal device in telecommunications systems and supports both multifrequency and pulse dialing methods. The device features a robust construction and is designed for industrial applications where high mechanical loads and environmental influences occur.

Applications
The A24 is particularly suitable for areas requiring high mechanical and climatic resistance, such as production halls, warehouses, outdoor areas, or manufacturing technology. The IP66 protection rating ensures the device is dust-tight and protected against water jets from any direction, making it suitable for outdoor use. The weather-resistant design enables reliable operation under difficult environmental conditions.

Functions and Equipment in Detail
The control panel of the A24 includes 16 robust keys designed for secure and long-lasting operation. An optional illuminated version is available, improving usability in poor lighting or darkness.
