Awoco 12VDC Easy-Install Magnetic Switch for Awoco Air Curtains
Best for single-door applications where a quick, straightforward magnetic switch is sufficient. The switch is designed for 12VDC systems and is meant to be mounted at the middle-top of the door and frame. It is not compatible with 110V power. Use this when the air curtain is already wired through Awoco’s control circuit, ensuring seamless activation with door movement.
Who this is for: small storefronts, offices, or residential setups using Awoco air curtains with one door. Why selected: simplicity and direct compatibility with standard Awoco control circuitry reduce installation time and complexity.
Caution: Not suitable for 110V systems; ensure you have a compatible 12VDC setup and one switch per door as noted, especially for double-door configurations.
Awoco Heavy Duty Commercial Plunger Door Micro Switch
Best for rugged installation environments where IP65-rated protection and robust construction matter. This switch features a built-in miniature limit switch with a strong aluminum shell and options for different actuation styles, designed to withstand moisture and oil exposure while providing reliable door sensing for air curtains.
Who this is for: commercial spaces like workshops or entryways with exposure to moisture or oils. Why selected: durability and versatility in actuator options.
Caution: It is a switch component rather than a complete sensor kit; verify compatibility with your air curtain’s control system and voltage requirements before wiring.
Gebildet Recessed Wired Magnetic Reed Switch (Set of 5)
Best for installations where the sensor should remain discreet. This 5-piece recessed magnetic reed switch set features a sensing distance around 10–15 mm and a compact footprint. Suited for doors with minimal visible hardware, it integrates with door sensors to trigger the air curtain on open/close events.
Who this is for: retailers or offices with a preference for concealed hardware. Why selected: discreet fit and reliable magnetic sensing in a small form factor.
Caution: The product uses a standard reed switch configuration; ensure it matches your air curtain’s control method and required actuation type (normally closed vs. normally open) for correct operation.
Hanchen Light 36” Air Curtain Magnetic Door Switch
Best for two-speed air curtain systems that need straightforward magnetic switching. This model supports two operation speeds, with a note that it is not an air conditioner. Installation steps emphasize mounting the plate, hanging the curtain, and connecting the magnetic switch for door-frame activation.
Who this is for: medium-traffic entrances where energy-saving and higher airflow need balancing. Why selected: dual-speed capability adds flexibility for different traffic patterns.
Caution: Verify power compatibility and confirm that a magnetic switch pairing matches your specific air curtain model to avoid misactivation.
Hanchen 36 Inch Air Curtain Magnetic Door Switch (2026 Version)
Best for upgraded, heavy-duty installations with dual-speed operation. The 2026 version offers enhanced airflow and a two-speed control system. Installation involves mounting, hanging the air curtain, and coupling the machine body with the door frame via the magnetic socket for reliable activation.
Who this is for: commercial entrances with higher throughput requiring robust sensing and flexible airflow. Why selected: improved motor and switch integration supports demanding environments.
Caution: Ensure compatibility with your air curtain and follow the included wiring diagrams to avoid miswiring the magnetic connection.
Crispaire 36-Inch White Air Curtain With Magnetic Door Switch
Best for high-performance indoor-outdoor barriers in retail or hospitality settings. The Crispaire model delivers up to 1,527 CFM with dual-speed control, designed to reduce HVAC load and improve comfort. It includes a magnetic door switch for automatic activation on entry and exit.
Who this is for: busy storefronts and restaurants seeking strong, continuous air barriers. Why selected: top airflow and dual-speed operation that adapt to peak and off-peak periods.
Caution: Not an air conditioner; it creates a barrier rather than heating or cooling air. Ensure the space can benefit from an air-curtain barrier without HVAC supplementation.
Light Curtain 917A61-AC110 Elevator Door Sensor
Best for universal 110V installations requiring a simple door sensor setup. This model is described as a universal AC110V light curtain/elevator door sensor, suitable for automatic triggering in entry control scenarios and compatible with standard 110V electrical systems.
Who this is for: facilities needing straightforward 110V door-sensor integration for air curtains or elevator access control. Why selected: broad compatibility with common electrical standards.
Caution: Specific use in elevator or door-control contexts; confirm the sensor’s electrical requirements and mounting method align with your door curtain system.
Buying Guide: Key Considerations For Air Curtain Door Sensors
- Door type and mounting: Choose a sensor that fits your door’s construction (single vs. double doors) and whether you prefer concealed or surface-mounted hardware.
- Voltage compatibility: Verify the switch’s voltage (12VDC vs 110V AC) matches your air curtain control system to avoid incompatibilities.
- Environment durability: For moist or oily areas, prioritize IP-rated or rugged switches for long-term reliability.
- Actuation type: Confirm whether you need normally open vs normally closed configurations to ensure proper triggering with your air curtain.
- Installation simplicity: Some switches offer quick mounting on frames or doors; others require more extensive wiring—plan for technician time if needed.
- Air curtain compatibility: Ensure the sensor integrates with your specific air curtain model, especially when brands differ (Awoco, Hanchen, Crispaire, etc.).
- Automatic vs manual control: Some systems offer auto activation with door movement, while others provide remote or manual control—match to your traffic pattern.
FAQ
- What is a door sensor for an air curtain used for?
Answer: It detects door movement to automatically trigger the air curtain, creating a barrier when doors open and reducing drafts and pests when closed. - Do I need a 12VDC sensor for all air curtains?
Answer: Not necessarily. Some systems use 110V AC, especially in commercial setups. Verify your air curtain’s voltage requirements before purchasing. - Can I use multiple door sensors for double doors?
Answer: Yes, but most curtains require one sensor per door. For double doors, an extra magnetic switch is typically needed to activate the curtain on both leaves. - Is installation difficult for these sensors?
Answer: It varies. Some switches are designed for quick attachment to door frames, while others require more extensive wiring and mounting. Refer to manufacturer diagrams for proper setup. - Do magnetic reed switches work with all air curtains?
Answer: They are common, but confirm compatibility with your specific model and control circuit to ensure reliable triggering. - Will these sensors add noticeable maintenance?
Answer: Generally low-maintenance, but periodic checks for alignment and wiring integrity help sustain reliable operation.
