Microwave Real Presence

KNX Secure Multifunctional Real Presence Sensor

EK-SG2-TP-P

Equipped with 24 GHz microwave radar technology, the Ekinex KNX Secure multifunctional real presence sensor reliably detects even the slightest stationary presence (such as breathing or typing). Prevents unwanted shut-off of lighting and climate systems when occupants are sitting still. The ultimate choice for hotel rooms, executive offices, conference spaces, and sedentary work areas.

Architectural Integration & Philosophy

Real presence detection technology redefines modern comfort automation. Thanks to 24 GHz continuous microwave scanning, it verifies human presence even when occupants remain completely still, preventing false-off interruptions. Its ultra-compact silhouette (Ø 65 mm outer diameter) integrates gracefully into ceilings with zero visual intrusion.
