24GHz Wide Microwave Motion Sensor for Automatic Doors SS-24G01 - Silver

A slim horizontal radar motion sensor in a sleek metallic silver finish, powered by the advanced SS-24G01 24.125 GHz microwave Doppler module. Engineered specifically for high-traffic commercial sliding and swing doors, it eliminates entry bottlenecks and false triggers by instantly detecting human approach speeds down to 5 cm/s. Supporting broad low-voltage dual power (12V–24V AC/DC) with a standard voltage-free dry contact relay output (COM/NO), it integrates seamlessly with modern aluminum storefronts and architectural entryways.

Key Features:

• Slim Horizontal Design: Perfectly aligns with aluminum transoms and modern commercial glass door headers.
• Instant Radar Tracking: High-frequency 24.125GHz SS-24G01 Doppler module ensures rapid response without temperature lag.
• Ultra-Low Speed Sensitivity: Accurately tracks slow-moving pedestrian traffic starting from 5 cm/s.
• Multi-Axis Antenna Adjustment: Flexible mechanical bracket allows custom vertical tilt and horizontal rotation.
• Universal Voltage Support: Operates reliably across 12V to 24V AC/DC inputs.
• Standard Dry Contact Output: Clean COM/NO relay switch compatible with all major commercial door controllers.
• Precise Sensitivity Dial: Integrated potentiometer enables quick detection boundary tuning.
• Industrial Flame-Retardant Housing: Durable engineering ABS construction built for demanding commercial environments.

💡 Technology (Simply Explained):

The sensor utilizes high-frequency microwave radar based on the Doppler physical principle. The internal SS-24G01 module continuously transmits 24.125 GHz electromagnetic waves across the entrance zone. When a person or vehicle moves into the field, the frequency of the reflected wave shifts. The onboard microprocessor analyzes this shift instantly and triggers the output relay, sending a clean open signal to the door controller without the thermal interference typical of infrared sensors.

Orientation & Coverage:

Features a fully adjustable internal antenna mechanism. The antenna tilts vertically to set forward reach up to 3.5 meters high and rotates horizontally to center coverage strictly along the direct walking path. This directional precision filters out parallel sidewalk traffic and prevents unwanted opening cycles.

Compatibility:

Fully compatible with all commercial automatic sliding glass doors, motorized swing doors, revolving doors, and access-controlled speed gates. Connects directly to the primary controller board (PCBD) via standard dry contact trigger inputs (Normally Open - NO).

Load & Power Limits:

Engineered strictly for low-voltage signal triggering. The internal relay output supports control signals up to 42V AC/DC. Direct connection to 220V mains electricity or driving heavy door drive motors directly through the sensor terminals is prohibited; it must interface solely with the controller's trigger port.

Practical Applications & Use Cases:

Ideal for storefront entrances in shopping centers, banks, medical centers, corporate headquarters, and hotels featuring silver aluminum profiles. Provides seamless, hands-free accessibility while maintaining indoor climate efficiency by keeping doors shut during cross-traffic.

Automation & Logic Sequences:

Integrates directly into building automation setups. A single detection trigger initiates the door opening cycle and can simultaneously activate air curtains or entryway lighting arrays, maintaining passage readiness before executing a timed closure once the radar zone is clear.

Frequently Asked Questions:

Q: Does this microwave sensor work in high ambient summer temperatures?

A: Yes. Because it operates on 24.125GHz radio frequency radar rather than thermal differential infrared (PIR), ambient heat, direct sunlight, and hot wind do not degrade its detection accuracy.

Q: Can this sensor directly power a 220V door motor?

A: No. The internal relay provides a low-voltage dry contact signal (COM/NO) designed exclusively to trigger the door's main logic control board, not to drive heavy electrical loads directly.

Q: How do I reduce false door openings caused by pedestrians walking past the door?

A: Rotate the internal antenna. Adjust the horizontal angle inward and lower the sensitivity potentiometer (turn counter-clockwise toward MIN) to restrict the radar field strictly to the forward approach vector.

Installation & Wiring:

1. Remove the outer silver cover and fasten the horizontal base plate centered above the door transom using the supplied screws.
2. Plug the 4-pin JST harness into the integrated rear socket:

• Green & Brown wires: Power supply lines (12V-24V AC/DC).
• White & Yellow wires: Dry contact relay leads (COM & NO) to the door controller's open trigger terminals.

1. Adjust the antenna tilt and horizontal sweep, then tune the sensitivity potentiometer to match entryway dimensions.
2. Snap the front cover securely in place, apply power, and verify opening response upon stepping into the detection zone.

⚠️ Safety Precautions:

1. Isolate and disconnect main power before handling wiring connections on the door control board.
2. Ensure input power is strictly within the 12V-24V AC/DC limit; connecting directly to 220V mains will cause immediate hardware damage.
3. Avoid pointing the radar field at large vibrating metal sheets or motorized fans to eliminate phantom triggers.
