Duckbill Float Switch 304 Stainless Steel Liquid Level Sensor G1/2"

Duckbill Float Switch – 304 Stainless Steel Liquid Level Sensor G1/2" | DC 0–220V

Monitor and control liquid levels with precision using this Duckbill Float Switch. Built from durable 304 stainless steel (SUS304), this compact level sensor is engineered for reliability in demanding environments — from industrial tanks and agricultural equipment to household appliances and automotive systems. Its reed-switch design requires no separate power supply, making installation simple and hassle-free.

Made in Mainland China.

Key Features

• Multi-Point Control: Set control switch points at any desired liquid level position for versatile operation.
• Reed Switch Technology: No separate power supply needed — the built-in magnetic reed switch activates as the float rises or falls with the liquid level.
• High Reliability & IP-65 Protection: Junction box protection grade is IP-65 or above, keeping the internals safe from dust and water ingress.
• SUS304 Stainless Steel Construction: Handles high temperatures (up to 120°C), high pressure (up to 0.2 MPa), and exposure to various acids, alkalis, and densities.
• Wide Voltage Range: Compatible with DC 0–220V systems, making it suitable for a broad range of electrical setups.
• Lightweight & Easy to Install: G1/2" thread fitting for quick mounting in tanks, pipes, and vessels.
• Versatile Applications: Ideal for automobiles, industrial machinery, agricultural equipment, and household appliances.

Specifications

How It Works

The float switch operates on a simple yet reliable principle: a float containing magnetic material rides up and down with the liquid level. As it moves, it triggers the internal magnetic reed switch, which opens or closes an electrical circuit to detect the liquid level position — no complex electronics required.

Frequently Asked Questions

Q: What is a duckbill float switch used for?

A: A duckbill float switch is a liquid level sensor used to detect and control the level of water or other liquids in tanks, pipes, and vessels. It opens or closes an electrical circuit when the float rises or falls with the liquid, making it ideal for pumps, alarms, and automated liquid management systems in industrial, agricultural, and household applications.

Q: Is this float switch compatible with both AC and DC systems?

A: Yes. This duckbill float switch supports a working voltage range of DC 0–220V and a working current of 0.5–1.5A, making it compatible with a wide variety of electrical setups, including both low-voltage DC and standard AC control circuits.

Q: Can this stainless steel level sensor be used with corrosive liquids?

A: The sensor is constructed from SUS304 stainless steel, which offers good resistance to a range of acids, alkalis, and varying liquid densities. However, we recommend verifying compatibility with highly aggressive chemicals before use in extreme chemical environments.

Q: How do I install the G1/2" duckbill float switch?

A: The switch features a standard G1/2" threaded fitting, allowing it to be screwed directly into a tank wall, pipe fitting, or vessel port. No separate power supply is required — simply connect the switch contacts into your circuit, and the reed switch will activate as the float detects the liquid level.
