BurookHi Norman... I just remembered i didn't let u know.... everything worked out we made both the wired and the remot control opening work... they loved the item (assuming it will hold its own for the next 10 years or so) -
KiranYes I don’t doubt you. Jutai is one of the most confident companies I came across in China

Product Description
RVP42-7BW Cold Chain Logistics Radar Sensor Anti-Fog for Freezer Warehouse Automatic Door
Product Overview
The RVP42-7BW is a specialized industrial radar motion sensor engineered for cold chain logistics and freezer warehouse environments. Built on 24GHz Doppler radar technology with advanced digital signal processing, it delivers precise detection of vehicles and personnel approaching automatic freezer doors, even in foggy, icy, or condensation-heavy conditions.
Key Benefits for Freezer Warehouse & Cold Chain Applications
- Fog & Condensation Resistant - Maintains consistent detection performance despite moisture buildup on lenses or in high-humidity cold air.
- Sub-Zero Reliability - Operates flawlessly in temperatures as low as -30 °C, ideal for deep-freeze and cold storage zones.
- Accurate Vehicle & Pedestrian Detection - Identifies forklifts, pallet trucks, and workers with 95% accuracy, reducing energy waste from unnecessary door cycles.
- Fast & Responsive - Triggers in under 50ms to keep cold air loss to a minimum during door opening.
- High Interference Immunity - Suppresses electromagnetic noise from refrigeration units, motors, and LED lighting.
- Energy Saving - Reduces warm air ingress, helping maintain internal temperatures and lowering HVAC load.

Functional Highlights for Freezer Automatic Doors
- Moisture-Tolerant Detection - Anti-fog lens treatment prevents condensation from impairing radar performance.
- Direction Recognition - Differentiates between inbound and outbound traffic to optimize door cycles.
- Energy Efficiency - Minimizes warm air infiltration, protecting stored goods and reducing compressor workload.
- Reliable in Extreme Cold - Consistent operation in deep-freeze zones down to -30°C without performance drift.
- Flexible Configuration - Adjust sensitivity, relay hold time, and lateral motion filtering to suit high-traffic or low-traffic freezer aisles.
Comparison with Traditional Freezer Door Sensors
| Feature | RVP42-7BW Radar Sensor | Infrared Beam Sensor | Ultrasonic Sensor |
|---|---|---|---|
| Fog/Condensation Resistance | Excellent (anti-fog design) | Poor (optics fog up) | Moderate (signal scatter) |
| Cold Temperature Operation | -30°C to +60°C | Limited below 0°C | Limited below -10°C |
| Detection Accuracy | 95% | ~80% (alignment sensitive) | ~75-85% |
| False Alarm Rate | <1% | 5-10% | 3-8% |
| Response Speed | <50 ms | ~100 ms | 100-300 ms |
| Maintenance Need | Very low | Frequent realignment | Periodic cleaning |
Ideal Applications in Cold Chain Logistics
- Automatic doors for freezer warehouses
- Cold storage distribution centers
- Refrigerated loading docks
- Pharmaceutical cold rooms
- Food processing plants with chilled zones
Installation Recommendations
- Mount at 2-7 meters height, directed toward the doorway traffic path.
- Ensure the sensor's front lens remains unobstructed and free of ice build-up.
- Enable anti-EMI mode to counter interference from refrigeration compressors and lighting.
- Use lateral motion filter to ignore side traffic or equipment movement.
- Select sensitivity level based on door usage frequency and ambient moisture.
