IWD-24D Vehicle and Pedestrian Separation Radar Overview
The IWD-24D Industrial Radar Motion Sensor is engineered for high-speed fabric doors, cold storage roll-up doors, and automated vehicle access gates. Utilizing advanced 24.125GHz millimeter-wave technology, it analyzes electromagnetic reflection and velocity to accurately differentiate approaching forklifts/vehicles from cross-traffic pedestrians.
✓ Energy Saving & Climate Control: Keeps doors closed for pedestrian pass-by, significantly reducing HVAC thermal loss and cycle wear.
✓ Extreme Environment Ready: IP67 waterproof housing ensures reliable continuous operation across severe dock rain, dust, and -40°C cold storage.
✓ Fast Plug-and-Play Integration: Standard dry-contact relay terminals directly connect to major commercial gate and roll-up door operators.

FREQUENTLY ASKED QUESTIONS
Q1: How does the radar separate pedestrians from vehicles?
A: The IWD-24D operates at 24.125 GHz millimeter-wave to evaluate target speed, movement trajectory, and electromagnetic echo characteristics, reliably distinguishing metal vehicles from pedestrians.
Q2: Can I use this radar detector in outdoor wet or cold storage environments?
A: Yes. The unit features an IP67-rated waterproof ABS enclosure and operates reliably across temperatures from -40°C to +80°C.
Q3: How do I select one-way (approaching only) detection mode?
A: Keep the Purple and Brown wires disconnected (open circuit) for one-way approaching detection, or connect them (short circuit) for bi-directional detection.
Q4: Is the relay output compatible with standard commercial door controllers?
A: Yes. It provides standard dry-contact COM, NO, and NC relay outputs and connects directly to virtually any commercial door operator with a 12–24V DC auxiliary power supply.
