AC 85~265V PIR Infrared Ray Motion Sensor Switch Time Delay Adjustable Detector

The AC 85~265V PIR Infrared Ray Motion Sensor Switch Time Delay Adjustable Detector is a compact motion-activated switching device intended to detect human presence using passive infrared (PIR) sensing and control AC-powered lighting or loads within the 85–265V range. The unit incorporates an adjustable time-delay function so the output can remain energized for a user-selected interval after motion is no longer detected. This combination of PIR sensing and time delay makes the detector suitable for automating lights in areas where intermittent occupancy requires hands-free control.

Designed for straightforward integration, the detector is typically mounted in locations that require automatic on/off switching such as corridors, stairwells, entryways, utility rooms, or other spaces with intermittent use. It responds to changes in infrared radiation associated with moving occupants and switches the connected AC circuit accordingly. The adjustable time-delay lets installers tune how long the load remains on after the last detected motion, helping balance convenience and energy savings.

When planning installation, consider placement for clear line-of-sight to the monitored area and appropriate mounting height for reliable detection of occupants. The sensor is intended for use with AC mains within the specified voltage range; follow local electrical codes and safety practices during installation. For safe operation and to maintain warranty coverage, have connections made by a qualified electrician and avoid exposure to conditions outside the product’s ratings.

This detector provides a practical way to add occupancy-based control to lighting and other AC circuits in commercial, industrial, or residential settings where automatic switching and adjustable time delay are desired features.
