Description

The PTFA0100 utilizes a hermetically sealed reed switch actuated by a magnet within the float. When the liquid level rises, the float aligns the magnet with the reed switch, closing the SPST-NO (Single-Pole, Single-Throw, Normally Open) contact. This provides a simple, reliable on/off signal for level detection without complex electronics.

Designed for integration into appliance control boards and industrial PLCs, the switch is rated for direct switching of loads up to 10 VA. Its robust 30% glass-filled nylon 6.6 construction provides chemical resistance and mechanical strength, making it suitable for applications involving water, detergents, and other non-corrosive liquids.

Key Features

  • Reed Switch Actuation: Provides a reliable, hermetically sealed contact mechanism with long operational life.
  • Horizontal Mount Design: Ideal for side-wall installation in tanks and reservoirs with limited vertical space.
  • Durable Nylon 6.6 Housing: 30% glass-filled construction offers excellent impact resistance and dimensional stability.
  • Direct Load Switching: Capable of switching up to 5A at 200V AC/DC, eliminating the need for an intermediate relay in many applications.
  • Simple Functional Reversal: The sensing action (open/close) can be inverted by physically rotating the sensor 180 degrees.
  • High Electrical Isolation: Features a breakdown voltage of 250V and insulation resistance of 10^10 Ω for safety and signal integrity.

Applications

  • Liquid level control in commercial drink vending and coffee machines.
  • High/low-level detection in domestic and industrial washing machines.
  • Water tank level monitoring in HVAC systems and boilers.
  • Overflow protection and pump control in sump and reservoir management.
  • Liquid presence sensing in appliance manufacturing and process automation.

Frequently Asked Questions

What is the electrical rating of the PTFA0100 float switch?

The PTFA0100 is rated for a maximum switching power of 10 VA. It can handle up to 5 Amps at a maximum voltage of 200V AC or DC. This allows it to directly switch small pumps, solenoids, or indicator lights without requiring an additional relay.

How does the SPST-NO (Normally Open) contact function?

The switch features a Single-Pole, Single-Throw, Normally Open (SPST-NO) reed contact. The circuit is open (off) when the float is in its resting position. When the liquid level rises and lifts the float, the internal magnet aligns with the reed switch, closing the contact (on) to complete the circuit.

Can the sensing logic be inverted?

Yes. The sensing action can be reversed by physically rotating the entire sensor assembly 180 degrees. This changes the configuration so the circuit is closed when the float is down (low liquid level) and open when the float is up (high level).

What types of liquids is this switch compatible with?

The switch is constructed from 30% glass-filled nylon 6.6, which is resistant to water, detergents, and many non-corrosive liquids commonly found in appliances. It is not recommended for use with strong acids, bases, solvents, or oils that may degrade nylon.
