Product Details
Summary
The PD-PRW26D is a dual-mode motion sensor switch combining an infrared sensor and a microwave sensor. Due to their differing physical requirements for detecting movement, the infrared sensor detects motion only when there is lateral (tangential) movement, while the microwave sensor—based on Doppler effect principles—requires direct, head-on movement to detect motion. Both sensors are directional in detection, and the PD-PRW26D leverages this difference by integrating them into a single unit. The infrared sensor effectively captures lateral movements, while the microwave sensor responds best to direct, frontal motion, allowing each to operate at peak efficiency. This combination enables broader application in environments requiring multi-directional detection, offering higher detection resolution and virtually eliminating missed detections.

Sensor Information
Function
- Identify day and night automatically. Can adjust ambient light according to your desire: when turn to SUN (max), it will work in the daytime and at night.When turn to MOON (min), it will only work under less than10LUX circumstance. As for Adjustment, please refer to testing way.
- Time-delay is added continually: when it receives the second induction signal after the first inductor, it will compute time once more on the rest of the first time-delay basic. (Set time)
- Time-delay adjustment: it can be set according to your desire. The minimum is 8±2sec; the maximum is 8±2min.
(1) Light-control setting
It can be defined in the range of 2~2000 LUX. To turn the knob fully anti-clockwise is about 2 lux,fully clockwise is about 2000 lux.When adjusting the detection zone and performing the walk test indaylight,you should turn the knob fully clockwise.
(2) Time setting
It can be defined from 20sec (turn fully anti-clockwise) to 12min (turn fully clockwise). Any movement detected before this time elapses will re-start the timer. It is recommended to select the shortest time for adjusting the detection range and for performing the walk test.
NOTE: When the light be auto off,it will take 1 second before the sensor is ready to detect another movement,that is,only signal detected 1 seconds later can the light be auto-on.
The correct use of delay adjustment: it is used to adjust the delay time between the light on after the sensor detects the presence of the human body and the automatic light off. Users can adjust according to actual needs. Because microwave induction products have continuous induction function, in short, the sensor in the delay time before the end of any induction, the system will re-time, as long as the presence of people in the detection range, the light will not go out.
(3) Detection range setting(sensitivity)
The detection distance is minimum when turning counterclockwise to the bottom, and maximum when turning clockwise to the bottom. The maximum range of radar detection target is 4.5m straight line distance between the human body and the sensor, and the detection range is 1.5-4.5m.
Note: please don’t adjust the three functional knobs to excess. That is because the three functional knobs were connected to the components directly, there is a small stopper in each of the three components, when you adjust the knobs from start to end, the excessive turn will damage the stopper，and lead to the 360°non-stop turn around. The adjust range limit is 270°, please do pay attention to this.
Installation instruction
- Switch off the power.
- Set threaded tubes into the power cord and control line.
- Connect the power and the load with the sensor according to the connection-line diagram.
- Turn the knobs to the ideal conditions(Please define the settings as per the above SETTING MANNER ONE part mentioned).
Connection-wire diagram
Test
- Turn LUX knob clockwise to the maximum (SUN). Turn time knob anti-clockwise to the minimum.Turn sensor knob clockwise to the maximum.
- Power connected, the load controlled will start working and stop working 8±2 seconds later when there is no continual signal detected.
- Once detected, the load works and the indicator on and stops working 8±2 seconds later when there is no continual signal detected.And if signal detected 4 seconds later, the load should start working and the indicator on and stop working 8±2 seconds later when there is no continual signal
- Turns LUX knob anti-clockwise to the minimum. If it is tested under the circumstance above 10LUX, load should not work after induction load stop working; but if you cover the detection window with opaque objects (towel etc), the load works. Under the condition of no induction signals, the load should stop working within 8±2 sec. detected.
