Description:
Installation sensor EEN002 for twilight switch. EEN101 (EEN101)
The Hager EEN002 flush-mounted sensor is a dedicated light-sensitive probe designed to work in combination with the Hager twilight switch EEN101. Its purpose is to reliably detect ambient brightness and enable automatic switching of lighting depending on the level of daylight, for example for outdoor lighting, façade illumination, pathways, parking lots or shop windows. Installed in a suitable flush-mounting box in the façade or another exposed area, the sensor continuously measures the prevailing light level and transmits this information to the associated twilight switch, which then switches the connected loads on or off according to the configured threshold.
Technically, the EEN002 is engineered as an external sensor head for the EEN101 system, optimized for stable and long-term operation in building environments. It is constructed for fixed installation, typically in a wall or other stationary surface, and designed for use in conjunction with low-voltage control circuits as specified by the EEN101. The sensor is tailored to detect illuminance in the typical range required for twilight applications, enabling a defined switching point around dusk and dawn. Its compact design allows discreet integration into façades without impairing the architecture, while still ensuring adequate exposure to ambient light.
In terms of application, the EEN002 is ideal wherever lighting should operate automatically depending on natural daylight: outdoor and garden lighting in residential buildings, access ways and driveways, security and safety lighting in commercial properties, as well as decorative or advertising lighting that should only be active when it is actually dark. By coupling the sensor with the EEN101 controller, users can avoid unnecessary manual switching and ensure that lights are not left on during the day. This not only increases comfort and safety, but also contributes to energy-efficient building operation.
The advantages for the user include increased convenience, better energy efficiency and potentially longer lamp life, as lighting runs only when needed. Automated dusk-dependent switching supports compliance with energy-saving strategies and can help reduce operating costs. The system solution from Hager (EEN002 sensor + EEN101 twilight switch) is coordinated and designed for reliable, consistent switching behavior over time, which is particularly important in outdoor or semi-outdoor installations.
Hager is an established European manufacturer of electrical installation and building automation solutions, known for reliable, installation-friendly products that support modern, safe and energy-conscious building technology. The company places emphasis on quality, long service life and system compatibility across product families, which benefits installers and end users alike through simplified planning and maintenance.
Hager also communicates various initiatives in the fields of sustainability and environmental responsibility, such as improving energy efficiency in buildings through intelligent control solutions and optimizing internal processes to reduce resource consumption. By using an automatic twilight control system like the combination of EEN002 and EEN101, customers actively contribute to reducing unnecessary energy use for lighting and thus to lowering their environmental footprint. The purchase and use of such demand-oriented lighting control is therefore not only a question of comfort and safety, but also a concrete step toward more sustainable building operation and responsible use of energy resources.
