External light sensor MACLEAN MCE34 — ambient luminosity sensor for outdoor use, up to 2000W

The External light sensor MACLEAN MCE34 monitors ambient luminosity and automatically controls connected lighting and outdoor electrical devices. Designed for outdoor installation, the sensor responds to changing daylight conditions to switch loads up to 2000W. It is suitable for use with street lighting, garden lamps, signage illumination and other outdoor circuits where automatic dusk-to-dawn control reduces manual intervention and supports energy-saving operation.

Advantages

The MACLEAN MCE34 offers reliable, weather-resistant operation for outdoor environments and simplifies lighting automation by switching based on measured ambient light. Its ability to handle loads up to 2000W makes it compatible with a wide range of lighting fixtures and outdoor electrical devices. Installation and integration are straightforward thanks to a compact form factor intended for external mounting and clear functional behavior tied to daylight levels.

Suitable for

• Automatic switching of street and pathway lighting
• Garden and yard lighting control
• Illumination of outdoor signs and façades
• Basic energy-saving automation for outdoor circuits

Key specifications

• Function: ambient light level detection for automatic switching
• Installation: designed for outdoor mounting
• Maximum supported load: up to 2000W
• Primary application: control of lighting and outdoor electrical devices based on daylight

How to use

Mount the sensor in a location where it can measure representative ambient light without direct obstruction from fixtures or nearby artificial light sources that could affect readings. Connect the sensor into the lighting circuit following local electrical regulations and the device wiring instructions. Once installed, the MCE34 will switch connected loads automatically according to ambient luminosity thresholds, turning lights on at low light levels and off when sufficient daylight is detected.

Usage recommendations

For reliable operation, position the sensor away from direct lamp output or reflective surfaces and avoid locations with frequent artificial light interference. Verify that the connected lighting load does not exceed the specified 2000W limit and ensure wiring and mounting comply with applicable safety standards and local codes.
