Awoco TZ-6001-15A Heavy Duty Door Micro Switch
Designed for air curtain applications, this switch uses a built-in CM miniature limit switch housed in a rugged aluminum shell. It is water-proof and oil-proof, with compatibility to CM micro switch ratings. It supports a variety of actuators for flexible installation, making it suitable for commercial entrances where reliable door sensing is critical.
Mars TZ6112 Combo Microswitch
This combination microswitch supports 125-250V and up to 20-Amp, providing robust sensing for air curtain applications. The combo approach can simplify installation by offering a versatile, high-current solution suitable for demanding entrances where doors experience frequent use and higher inrush currents.
Awoco 12VDC Magnetic Switch For Air Curtains
This magnetic switch is designed for straightforward installation on Awoco air curtains. It attaches to the door frame and door edge, closing the circuit when the doors meet. Note that it operates at 12VDC and is intended for use with Awoco’s magnetic switch controlled circuit; double-check compatibility for two-door setups since an extra switch may be needed for double doors.
Baomain TZ-6 / BM-6001 Sealed Limit Switch
This sealed 15A/250VAC limit switch is a direct OEM replacement for TZ-6/TZ-6001 styles commonly used with various air curtain brands. The IP65 rating provides protection against dust and water jets, making it suitable for oily or wet environments where reliability matters for door sensing during frequent use.
DuraSteel TZ-6002 Heavy Duty Door Micro Switch
With a horizontal roller plunger design, this switch is tailored for sliding doors and windows in air curtain systems. It features a built-in CM miniature limit switch, a sturdy aluminum shell, and waterproof/oil-proof construction. It supports 220V or 110V operation at 15A, offering flexibility for various commercial installations.
DuraSteel TZ-6003 Heavy Duty Door Micro Switch
This model mirrors the rugged design of TZ-6003 for vertical roller plunger applications, suitable for roll-up or push/pull doors. It uses a CM miniature limit switch and a durable aluminum shell, with IP-rated protection and compatibility for both 220V and 110V at 15A, making it a versatile option for diverse door configurations.
Buying Guide: Key Purchase Considerations
- Voltage and current rating: Choose switches rated for the door motor’s voltage and current to handle inrush currents without arcing or premature wear. Most options listed here support 110-120V or 220-240V and 15A-20A, which covers standard commercial air curtain requirements.
- IP rating and environment: Environments with water, oil, or dust demand IP65 or better. Sealed bodies prevent moisture ingress and extend life in kitchens, loading docks, and industrial entrances.
- Mechanical design: Horizontal versus vertical roller plungers suit different door types (sliding vs. push/pull). Consider whether a magnet switch is preferred for non-contact sensing or a physical plunger for direct actuation.
- Compatibility: If using an integrated circuit (e.g., magnetic switch controlled circuit), ensure the door switch is compatible with the air curtain’s control logic to enable automatic on/off with door status.
- Ease of installation: Look for switches with straightforward mounting, multiple actuator options, and clear wiring diagrams. Some models include built-in limit switches to simplify wiring and reduce components.
- Durability and environmental resistance: Aluminum housings, oil-proof seals, and CE/UL listings indicate reliability in busy entrances. For humid or oily zones, sealed, CE-rated units are preferable.
- Maintenance and replacement: Availability of OEM replacements and common form factors (TZ-series, BM-series) reduces downtime and simplifies stocking of spare parts.
- Double-door configurations: If there are two doors, plan for extra magnetic or switch units to ensure seamless door-sensing across all entry points.
- Fail-safe behavior: Ensure the switch’s default state matches your operational needs (e.g., normally open vs normally closed) to avoid unintended curtain operation during power loss or maintenance.
Overall, the highlighted options provide a spectrum from magnetic switches for quick installations to sealed, high-current microswitches designed for heavy-use doors. The ideal choice depends on door type (sliding, push/pull, or roll-up), environmental exposure, and the air curtain model in use. When selecting a replacement, verify the exact mounting footprint, actuator type, voltage, current rating, and whether the door switch should automatically control the curtain based on door position.
