S+S In-ceiling light intensity sensors - DHKF U

Introduction

Discover the innovative S+S In-ceiling light intensity sensors - DHKF U from the renowned manufacturer S+S Regeltechnik GmbH. These sensors are designed to revolutionize the way lighting is controlled and optimized in various spaces.

Key Features and Benefits

Designed for in-ceiling installation, the PHOTASGARD® DHKF light sensor features six switchable measuring ranges, providing the functionality of six devices in one. This versatility allows for precise light measurement in different environments.

The sensor is optimized for human eye sensitivity, with the highest sensitivity in the 350 to 820 nm range. Equipped with a special filter, it accurately measures natural and artificial light with high color temperatures, making it ideal for daylight-dependent lighting control and sun protection.

With a voltage supply range of 24 V AC (± 20%) and 15–36 V DC, the sensor offers a wide compatibility range. The multiple switchable measuring ranges, from 0 to 60 kLux, ensure accurate light measurement in various settings.

The sensor's housing is constructed from UV-resistant polyamide with 30% glass bead reinforcement, providing durability and longevity in diverse environments. The quick-connect head enables easy and swift installation, while the separate housing for the converter ensures efficient operation.

Utilized for daylight-dependent constant light control, as well as controlling lights, blinds, and sun protection systems, the sensor enhances energy efficiency and creates a comfortable lighting environment.
