Motion Sensor El Home MD-18B7 AC 230V for Lighting Control

The Motion Sensor El Home MD-18B7 AC 230V for Lighting Control is a ceiling-mounted passive infrared (PIR) detector designed to automate lighting circuits on a standard 230V AC supply. It detects human movement within its coverage area and switches lighting loads accordingly, providing hands-free operation for corridors, stairwells, public areas and residential rooms. The sensor is intended for simple occupancy-based control where automatic on/off switching reduces energy use and improves convenience.

Advantages

This ceiling motion sensor offers reliable passive infrared detection on a 230V mains supply, enabling direct control of lighting without additional power supplies. Its automatic switching reduces unnecessary runtime of fixtures and contributes to lower energy consumption. Ceiling mounting provides wide-area coverage and discreet installation, while the device’s design supports straightforward integration into basic lighting circuits.

Suitable for

• Corridors and hallways in residential or commercial buildings
• Stairwells and landings where automatic lighting is required
• Public areas such as lobbies, entrances and shared spaces
• Utility rooms, storage areas and other spaces with intermittent occupancy

Key specifications

• Supply voltage: AC 230 V
• Mounting type: ceiling-mounted
• Detection technology: passive infrared (PIR)
• Function: automatic switching of lighting based on detected motion
• Application: occupancy-based control for indoor lighting circuits

How to use

Install the sensor on the ceiling at the recommended height and location to maximise coverage of the target area, avoiding direct exposure to windows or heat sources that could affect detection. Connect the sensor to the lighting circuit following local electrical regulations and ensure the mains supply is switched off during installation. After powering, adjust orientation and, if available, any built-in sensitivity or time-delay settings according to the required behaviour so lights activate when movement is present and switch off after the desired absence interval.

Usage recommendations

Position the sensor centrally for uniform coverage and keep it clear of direct airflow from HVAC vents. For stairwells and long corridors, use multiple sensors or place the unit where occupancy movement is most reliably detected. Periodically check connections and clean the sensor surface to maintain reliable detection performance.
