The Behnke 20-2440 is a module motion sensor for use in telecommunications systems. It operates using electromagnetic waves and detects movements by changes in distance in its surroundings. Upon detecting movement, the sensor can trigger a predefined action, for example, activating a camera function or sending an email. The device is designed as a compact module that can be integrated into existing systems, and is particularly suitable for applications in industrial monitoring or security technology.

Applications

The sensor is designed for indoor use and can be employed in various application scenarios, such as in production halls, warehouses, or office buildings. It is suitable for detecting movements in defined areas and initiating corresponding system responses. The configurable range of 0.5 to 10 meters allows flexible adaptation to different room sizes and monitoring requirements. The horizontal field of view is at least 80°, with a significantly larger angle in close proximity, enabling efficient coverage of areas. Vertically, the detection angle ranges between 40° and 110°, with the exact extent depending on the distance to the object.

Functions and Equipment in Detail

The sensor features a potential-free relay serving as an output signal, which can be integrated into existing control or alarm systems. Dimensions are 90 mm height and 90 mm width, allowing the module to be compactly and space-saving integrated into enclosures or other installation units. The housing is made of aluminium, ensuring high mechanical stability and heat dissipation. The module's colour is grey, enabling unobtrusive integration into technical environments.

Technology Explained Simply

The sensor uses electromagnetic waves for motion detection. It registers distance changes in its surroundings caused by the movement of an object. This detection occurs without direct optical line of sight, allowing flexible placement. The range is configurable, enabling the sensor to be adjusted to a shorter or longer distance according to requirements. Horizontal and vertical coverage varies depending on distance, with the detection angle being particularly large in close proximity to ensure comprehensive monitoring.

Compatibility and Accessories

The module is designed as a TK system module and can be integrated into existing telecommunications or security systems. When installed in systems with a/b electronics, a power supply is required to ensure reliable operation.

Mounting and Installation

Mounting is carried out in standard enclosures or technical housings. Due to its compact dimensions of 90 x 90 mm, the module is easy to integrate. Installation requires connecting the relay output to the corresponding control or alarm interface. When used in systems with a/b electronics, a power supply must be connected to ensure power supply.

Advantages in Operation

The sensor offers flexible and reliable motion detection with a configurable range and a wide detection angle. The potential-free relay enables easy integration into existing systems. The aluminium housing ensures a robust and long-lasting construction. The grey colour and compact design support unobtrusive integration into technical environments.
