JUNG KNX snímač prítomnosti Standard 1,10 m LS 3181 WW (LS3181WW) snímač prítomnosti alpská biela

The JUNG KNX Automatic Switch LS 3181 WW is a high-quality presence detector and motion sensor designed for flush-mounted installation in KNX building automation systems. With an optimal mounting height of 1.10 m, it provides reliable detection for presence and motion in indoor environments. The device features passive infrared (PIR) technology and integrates a brightness sensor with a range of 10 to 2000 Lux. It is compatible with the JUNG LS-Design series (e.g., LS 990, LS design, LS plus) and comes in an elegant Alpine White (Alpinweiß) finish.

Advantages

This KNX automatic switch offers two independent channels for controlling lighting, HVAC, or other loads. It supports fully automatic and semi-automatic operating modes, and parameters such as sensitivity, time delay, and brightness threshold are adjustable. Additional functions include short-term presence, staircase function, master/slave operation, and scene control, providing flexibility for various automation scenarios.
