Description

The MCPLS Series float switch operates on a buoyancy principle, where the internal float rises or falls with the liquid level, mechanically actuating a single-pole, single-throw (SPST) normally-open switch. This action provides a direct electrical signal for controlling pumps, alarms, or indicator lights. The switch features a maximum differential travel of 3.5mm, providing a defined hysteresis to prevent contact chatter during level transitions near the set point.

Constructed with a polypropylene housing and ruthenium contact points, the sensor offers reliable performance in water, mild chemicals, and other compatible liquids. Its miniature form factor, with an 18mm diameter and 29.5mm external height, allows for installation in confined spaces. The device is designed for straightforward integration into 130V AC control circuits commonly found in industrial and commercial fluid handling systems.

Key Features

  • Vertical miniature float switch with SPST-NO (Form A) contact configuration.
  • Polypropylene body provides excellent resistance to water and many chemicals.
  • Ruthenium contact material ensures low contact resistance and long electrical life.
  • Precision M8 x 1.25 mounting thread for secure and sealed installation.
  • 300mm flying lead wires (approx.) facilitate direct connection to terminal blocks.
  • Compact 18mm diameter and 29.5mm height for space-constrained tank designs.
  • Wide operating temperature range from -20°C to +80°C.
  • Maximum differential travel of 3.5mm provides stable switching hysteresis.

Applications

  • High/low level detection and pump control in residential water storage tanks.
  • Liquid level monitoring in industrial chemical processing and mixing vessels.
  • Overflow protection and sump pump control in HVAC condensation systems.
  • Fluid level sensing in agricultural irrigation and livestock watering systems.
  • Fail-safe level indication in marine bilge and fuel tank applications.

Frequently Asked Questions

What is the electrical rating and contact configuration of this float switch?

This Multicomp Pro float switch uses a Single-Pole, Single-Throw, Normally-Open (SPST-NO or Form A) contact configuration. The contacts are rated for a maximum switching voltage of 130 Volts AC. The ruthenium contact material ensures reliable switching performance with low resistance over many cycles.

How do I mount and install the MCPLS Series float switch?

The switch is designed for vertical mounting via its M8 x 1.25 metric thread. It should be installed through a tapped hole or suitable fitting in the side or top of the tank at the desired liquid level set point. Ensure the polypropylene body is compatible with the liquid medium. The 300mm flying leads can be connected directly to your control circuit's terminal blocks.

What is the differential travel, and why is it important?

The differential travel is the vertical distance the float must move between the switch opening and closing points, with a maximum of 3.5mm for this model. This hysteresis prevents rapid on/off cycling (chatter) when the liquid level hovers near the switch point, providing stable control signals for pumps or alarms and extending the switch's mechanical life.

What liquids and temperature ranges is this switch suitable for?

The polypropylene (PP) body offers good chemical resistance to water, many aqueous solutions, and mild chemicals. Always verify material compatibility with your specific fluid. The switch operates reliably within an ambient temperature range of -20°C to +80°C, making it suitable for both indoor and many outdoor applications.
