Microwave Motion Sensor BEMKO B52-SES71WH 1200W 360° rectangular IP20 white

BEMKO B52-SES71WH is a microwave motion sensor for indoor lighting control with a compact rectangular white housing and IP20 protection. It detects movement across a full 360° coverage pattern and is specified for switching loads up to 1200W. The sensor is intended for presence-triggered switching of luminaires, enabling automated on/off operation without physical contact and contributing to energy-efficient lighting management in offices, corridors, storage rooms and other interior spaces.

Advantages

The sensor provides reliable 360° detection based on microwave technology, which is less affected by ambient light and temperature variations compared with traditional passive infrared sensors. Its 1200W switching capacity supports a wide range of lighting loads, while the rectangular white housing blends with standard indoor fixtures and installations. IP20 protection makes the device suitable for dry indoor environments, and the hands-free operation improves convenience and hygiene in shared spaces.

Suitable for

• Office rooms and meeting areas for automated lighting control
• Corridors and stairwells where presence detection ensures safety and energy saving
• Storage rooms and utility areas that require occasional occupancy-based lighting
• Public indoor spaces such as hallways, reception areas and classrooms

Key specifications

• Detection technology: microwave motion detection
• Coverage: 360° detection pattern
• Maximum switching capacity: 1200W
• Housing: rectangular, white finish
• Ingress protection rating: IP20 (suitable for dry indoor environments)

How to use

Install the sensor according to local electrical codes and the manufacturer's installation instructions, ensuring it is mounted at the recommended height and orientation to achieve optimal 360° coverage. Connect the sensor inline with the lighting circuit so it can switch the load up to the specified capacity. After wiring, adjust any available sensitivity or time-delay settings if present to match occupancy patterns in the room. Test the sensor operation by walking through the detection area and confirming reliable switching on and off of the connected luminaires.

Usage recommendations

For reliable performance, mount the device in a location free from moving objects such as fans or HVAC outlets that could trigger false detections. Use the sensor in dry indoor environments consistent with its IP20 rating and avoid exposure to direct water or high humidity. Where dimming or electronic drivers are used, verify compatibility with the sensor and the total connected load stays within the 1200W limit.
