Cable Float Switch

FT-100/FT-300

DESCRIPTION
Features

Single-Point Float Switch

The FT-100 and FT-300 Series Cable Float Switches are cost-effective, reliable, and ideal for simple alarm and water level control applications. These traditional float switches provide highly repeatable performance. The FT-100 offers multiple switching options, including NO (Normally Open), NC (Normally Closed), or SPDT (Single Pole Double Throw), while the FT-300 is available with NO or NC connections.

Designed with budget-conscious users in mind, these float switches deliver consistent and accurate water level detection. They are perfect for simple, single-point alarming applications without compromising on quality. The FT-100 and FT-300 switches are built for durability, featuring high-impact, corrosion-resistant polypropylene housing and a standard 6-meter (20 ft.) cable length. Other cable lengths are available in 5 ft. increments.

Superior Durability: Highly chemical resistant
Trusted Performance: Proven reliability in operation
Installation Flexibility: Not sensitive to rotation

What are the primary differences between the FT-100 and FT-300 float switches?

The FT-100 offers multiple switching options, including Normally Open (NO), Normally Closed (NC), or Single Pole Double Throw (SPDT), with a 1.5-inch switching differential. The FT-300 provides NO or NC connections with a 4.0-inch switching differential and is designed for low-current switching applications.

What applications are these float switches best suited for?

Both models are ideal for simple alarm applications, water level monitoring, and pump control. They are commonly used in sump pumps, wastewater systems, and other fluid monitoring setups where reliability and cost-effectiveness are key.

What materials are the FT-100 and FT-300 float switches made of?

Both models feature a high-impact, corrosion-resistant polypropylene housing, ensuring durability in various fluid environments.

How do these switches activate?

The float switches activate when the water level causes the float to rise or fall, triggering the switch immediately above or below the activation point.

Can the FT-100 and FT-300 be used in corrosive liquids?

The polypropylene housing is corrosion-resistant, making these switches suitable for many water-based applications. However, for highly corrosive or chemical-heavy environments, consult with APG to determine suitability.
