Microwave PIR Sensor for Automatic Doors, 12-24V AC/DC

A microwave PIR sensor is a dual-technology automatic door sensor that combines microwave radar with infrared detection to identify approaching pedestrians and monitor the door area for presence. The SUCH microwave PIR sensor applies this principle with a long-range 24.125GHz microwave module for activation and a short-range active infrared (AIR) array, effective up to 850mm, for close-range presence and safety monitoring, mounted at heights from 2m to 3.5m. Its microwave detection angle adjusts from 20°–80° tilt with ±15° horizontal coverage, while the infrared beam width and depth angle (-6° to +6°) can be tuned independently to match door size and traffic patterns. Rated IP54 and powered by 12-24V AC/DC, it suits sliding and swing automatic door sensor installations in commercial entrances, retail storefronts, and public facilities.

Feature

• Microwave and Active Infrared Dual Detection — Combines long-range microwave activation with a short-range active infrared (AIR) array for close presence detection, reducing false triggers common to single-technology automatic door sensors.
• Long-Range Microwave Activation (20°–80° Tilt, ±15° Horizontal) — Detects approaching pedestrians from a distance; angle adjusts to match door width and approach direction without relocating the unit.
• Short-Range Infrared Presence Detection (Up to 850mm) — Adjustable beam width and depth angle (-6° to +6°) confirm presence directly at the door area, complementing the microwave's wider activation range.
• DIP Switch Sensitivity Settings (Low / Medium / High / S-High) — Sensitivity is matched to mounting height from 2m up to 3.5m per site conditions.
• Configurable Presence Timer (30s / 60s / 180s / 600s) — Holds the door open while a person remains in the detection zone, with a self-healing function that relearns the background if the infrared field changes.
• IP54 Protection Rating — Suitable for semi-exposed entrances subject to dust and light moisture.
• Wide Voltage Input (12-24V AC/DC) — Compatible with standard automatic door controller power supplies.
• Fast Microwave Response (<0.3s) and 15-Second Automatic Calibration — Shortens setup time during installation and reduces manual adjustment at commissioning.
