Motion sensor FF DR-04B PIR, black, IP65, model DR-04B

The FF DR-04B PIR motion sensor in black with an IP65 rating is a compact passive infrared detector designed for automatic control of lighting and basic security systems. It senses changes in infrared radiation caused by moving people or objects and switches connected circuits accordingly. The weather-resistant housing and IP65 protection make this model suitable for both indoor and outdoor installations where dust and water ingress protection is required, such as building entrances, corridors, porches and external lighting fixtures.

Advantages

This motion sensor uses passive infrared (PIR) technology for reliable detection of human movement while maintaining low power consumption. The compact black housing provides discreet integration with most fixtures and building facades. IP65-rated sealing protects the electronics from dust and water jets, allowing installation in outdoor or semi-exposed locations. The sensor is intended for simple motion-triggered switching of lights or alarms, offering straightforward functionality without complex setup.

Suitable for

• Automatic switching of outdoor lighting such as porch, pathway and facade lights
• Indoor corridors, stairwells and entrance areas where occupancy-triggered lighting is needed
• Basic security activation for alarms or cameras when motion is detected
• Energy-saving lighting control in residential, commercial and utility spaces

Key specifications

• Detection type: Passive Infrared (PIR)
• Housing color: Black
• Ingress protection: IP65 (dust tight and protected against water jets)
• Mounting: Wall or ceiling mounting suitable for sheltered and exposed locations
• Typical applications: Lighting automation and basic motion detection for security

How to use

Install the sensor on a stable surface at the recommended height and orientation for the coverage area, ensuring the detection zone faces the intended approach path. Connect the sensor to the lighting or control circuit according to local electrical codes and wiring diagrams supplied with the device. After power-up, test the detection range by walking through the coverage area and adjust position or mounting angle as needed to avoid false activations from nearby heat sources or moving vegetation. Ensure electrical connections are made with power isolated and by a qualified person if required by local regulations.

Usage recommendations

For reliable performance, avoid installing the sensor near air-conditioning vents, heating units or direct sunlight, and keep the detection area free of rapidly moving foliage. Periodically check the housing seal and mounting hardware to maintain IP65 protection and clean the sensor lens with a soft, dry cloth to remove dust or debris.
