Benefits
- Supports KNX (TP) projects with an integrated KNX bus coupler, helping consultants and installers specify a complete KNX sensor point using the exact ABB model PMH/U2.1.1-885.
- Provides 360° sensor detection range and a circular detection range of up to Ø 10 m for the stated mounting heights of 2.5 m, 3 m and 4 m.
- Includes integrated brightness, temperature and humidity sensors, allowing the device to contribute multiple measured values within one KNX sensor product.
- Offers adjustable detection range via the ETS application, supporting project-specific commissioning based on the ABB application data.
- Supports constant light switching with up to two independent channels and up to 2 outputs for brightness-dependent switching of two light bands in the area.
- The black finish, similar to RAL 9005, supports projects where the sensor appearance must be coordinated with dark ceiling or interior designs.
