Motion sensor Steinel IS 345 MX-E KNX V3AP – model 058296, KNX-enabled presence detector

The Steinel IS 345 MX-E KNX V3AP is a KNX-enabled presence and motion detector engineered for building automation. Designed for mounted installation in corridors, offices and communal areas, it detects movement and occupancy to control lighting and energy systems via KNX integration. The sensor combines presence detection with configurable range and sensitivity, enabling automatic switching and timed control to optimize comfort and consumption in commercial and residential installations.

Advantages

The device offers precise motion and presence detection with integration into KNX networks for centralized control. Its adjustable detection range and time settings allow tailored responses to specific spaces, while compatibility with KNX ensures interoperability with other building automation components. The sensor supports both manual and automatic operation modes and is built for reliable, continuous use in frequently visited areas.

Suitable for

• Corridors and stairwells in commercial and residential buildings
• Open-plan and individual offices for automated lighting control
• Communal areas such as lobbies, utility rooms and meeting zones
• Energy-saving lighting schemes and occupancy-based climate control

Key specifications

• Detection type: presence and motion detection
• Integration: KNX protocol compatibility for building automation
• Mounting: ceiling or wall mounting options suitable for interior spaces
• Detection range: configurable detection radius to suit room size
• Adjustment features: sensitivity and time delay settings
• Operating environment: indoor use, designed for corridors, offices and communal areas
• Output functions: automatic switching and presence signalling for lighting and control systems

How to use

Install the detector at the recommended mounting location and connect it to the KNX bus according to the installation guidelines and local electrical codes. Configure detection range, sensitivity and time delay through the device settings or KNX configuration tools to match the room layout and occupancy patterns. Test the sensor after commissioning to confirm correct detection zones and expected automatic switching behaviour. For adjustments, use KNX software or on-device controls where applicable to fine-tune performance.

Usage recommendations

Place the sensor to avoid direct exposure to windows or HVAC outlets that can cause false triggers. Select detection and time settings appropriate for the typical occupancy of the area to minimize unnecessary switching. Integrate with KNX lighting and HVAC scenes for centralized energy management and schedule regular functional checks as part of building maintenance.
