Motion sensor FF DR-04W (R-04B) PIR, white, IP65

The FF Motion sensor DR-04W (R-04B) is a wired PIR presence detector in white with IP65 protection, designed for reliable infrared movement detection in both indoor and outdoor environments. The compact sensor integrates into lighting and security systems to trigger automated switching of lights, alarms or control equipment where splash and dust resistance is required. Its design focuses on straightforward installation and continuous detection performance for routine presence-sensing applications.

Advantages

The DR-04W offers weather-resistant construction with IP65 ingress protection, allowing installation in areas exposed to splashes and dust. Its passive infrared technology provides passive motion detection without emitting radiation, enabling low-power, maintenance-light operation. The compact white enclosure blends with most mounting surfaces and supports wired connections for stable, continuous integration with lighting controls and alarm systems.

Suitable for

• Automatic switching of outdoor and indoor lighting
• Perimeter and entryway presence detection for security systems
• Control inputs for building automation and alarm triggers
• Areas requiring splash- and dust-resistant sensors such as porches, garages and service corridors

Key specifications

• Sensing technology: passive infrared (PIR)
• Mounting: surface or wall-mounted compact enclosure
• Ingress protection: IP65 for dust-tight and water-splash resistance
• Color: white housing suitable for visible installations
• Connectivity: wired connection for stable signal and power

How to use

Mount the sensor at an appropriate height and orientation to cover the desired detection zone, avoiding direct exposure to heat sources or reflective surfaces that can affect PIR sensitivity. Connect the sensor to the lighting or control circuit according to the system wiring diagram, ensuring power is isolated during installation. After wiring, test the detection coverage by walking through the monitored area and adjust position or angle if necessary to achieve consistent activation of the connected load or alarm.

Usage recommendations

To maintain reliable detection, install the sensor where air movement and direct sunlight are minimized; clean the housing periodically to remove dust and debris; and verify wiring connections and protective seals to preserve IP65 performance.
