Frequently Asked Questions
Q: What type of doors is this 24GHz microwave radar motion sensor compatible with?
A: This sensor is designed primarily for automatic sliding and swing doors in commercial and industrial settings. It works with any automatic door system that accepts a relay-output activation signal, including those commonly found in retail stores, office buildings, hospitals, and warehouses.
Q: How does a microwave radar motion sensor differ from a standard infrared (PIR) sensor?
A: Microwave radar sensors emit 24GHz radio waves and detect motion by measuring changes in the reflected signal — making them effective through non-metallic materials and less affected by temperature fluctuations or ambient light. Standard PIR sensors rely on detecting infrared heat changes, which can be less reliable in environments with varying temperatures or physical obstructions.
Q: What is the maximum detection range of this sensor?
A: When mounted at 2.2m height, the sensor covers a detection zone of 4m wide by 2m deep. At the maximum mounting height of 4m, the coverage zone expands accordingly, making it suitable for wide commercial entrances.
Q: Is this sensor suitable for outdoor installation?
A: The sensor carries an IP52/IP54 protection rating, meaning it is protected against dust ingress and low-pressure water splashes. It is best suited for covered outdoor entrances or semi-sheltered environments rather than fully exposed outdoor installations subject to heavy rain or direct water exposure.
Q: What power supply does this radar motion sensor require?
A: The sensor is compatible with 12–24V AC (±10%) and 12–30V DC power supplies, giving you broad compatibility with most standard automatic door controller power systems. Power consumption is under 2W, making it highly energy efficient.
