Finder 72.C1.0.000.0201 Float Switch, 10A with 2m Cable, Wall Mountable

Overview of the Finder 72.C1.0.000.0201 Float Switch

The Finder 72.C1.0.000.0201 is a compact, wall‑mountable float switch designed for reliable level detection in water and other liquids. It features a robust construction, a 10 A current rating, and an integrated 2 m cable that simplifies installation. This device is ideal for applications such as sump pumps, irrigation systems, cooling towers, and industrial tanks where precise level monitoring is essential.

Key Technical Specifications

• Current Rating: 10 A
• Cable Length: 2 m (pre‑wired)
• Housing Material: Polypropylene (PP) – resistant to corrosion, chemicals, and UV exposure.
• IP Rating: IP68 – fully protected against dust ingress and capable of withstanding continuous submersion.
• Operating Temperature Range: –40 °C to +80 °C
• Voltage Supply: 24 V DC (typical)
• Mounting Type: Wall‑mountable with a standard mounting flange.
• Switch Type: Normally open (NO) or normally closed (NC) configurations available.

Design Features and Construction

The Finder 72.C1.0.000.0201 incorporates a sealed polypropylene housing that protects the internal contacts from moisture, debris, and chemical attack. The float element is made of high‑density polyethylene (HDPE) and floats freely on the liquid surface, ensuring accurate level detection even in turbulent conditions.

The device’s integrated 2 m cable eliminates the need for additional wiring, reducing installation time and potential points of failure. The cable is shielded to prevent electromagnetic interference, which is particularly important in industrial environments where heavy machinery may generate noise.

Installation Guidelines

1. Select a suitable mounting location: Choose a wall or support structure that can accommodate the device’s flange and allow the float to move unhindered.
2. Mount the unit: Secure the housing with screws or bolts, ensuring it is level. The mounting flange should be flush against the wall for optimal stability.
3. Connect the cable: Attach the pre‑wired cable to the device’s terminals and route it to the control panel or relay. Use appropriate connectors rated for the operating voltage.
4. Position the float: Place the float on the liquid surface, ensuring it is free from obstructions. The float should be able to rise and fall with the liquid level without contacting the housing walls.
5. Test the circuit: Verify that the switch opens or closes at the desired level by simulating a change in liquid height.

Typical Applications

• Sump Pumps: Automatically start or stop pumps based on water level.
• Irrigation Systems: Control water flow to fields and greenhouses.
• Cooling Towers: Maintain optimal coolant levels for efficient heat exchange.
• Industrial Tanks: Monitor process fluids in chemical plants, refineries, and food processing facilities.
• Water Storage: Ensure safe operation of domestic or commercial water reservoirs.

Performance Characteristics

The Finder 72.C1.0.000.0201 delivers consistent performance across a wide temperature range, thanks to its polypropylene construction and sealed contacts. Its IP68 rating guarantees that the device can be submerged in water for extended periods without degradation, making it suitable for harsh environments.

The 10 A current rating allows it to control high‑power pumps or motors directly, reducing the need for additional relays in many installations. The normally open configuration is commonly used for safety interlocks, ensuring that a pump will not start until the liquid level reaches the desired threshold.

Maintenance and Longevity

Regular inspection of the float’s buoyancy and the housing’s seal integrity ensures long‑term reliability. Because the device is sealed against dust and water ingress, routine cleaning is minimal—typically a quick wipe with a damp cloth to remove any surface deposits.

The polypropylene material resists chemical attack from acids, alkalis, and salts, extending the service life even in aggressive media. The pre‑wired cable’s shielding also protects against corrosion, further enhancing durability.

Compliance and Standards

• IEC 60335-2-78: Safety requirements for electrical appliances used in water treatment and irrigation.
• EN 60204-1: Electrical equipment of machines – safety aspects.
• ISO 9001: Quality management systems, ensuring consistent manufacturing quality.

Installation Variants

The Finder 72.C1.0.000.0201 is available in several variants to accommodate different operational needs:

• Normally Open (NO): Commonly used for safety interlocks.
• Normally Closed (NC): Useful where a continuous operation is required until the level drops below a threshold.
• Dual‑Contact Versions: Provide both NO and NC contacts in a single housing, enabling complex control logic.

Conclusion

The Finder 72.C1.0.000.0201 Float Switch combines robust construction, reliable performance, and ease of installation to deliver precise level detection across a broad spectrum of industrial and commercial applications. Its wall‑mountable design, integrated cable, and high current rating make it an excellent choice for engineers seeking a dependable solution for fluid level monitoring.
