Madison M5600 Liquid Level Float Switch 1/4 Npt Spst

Product Description

The MADISON M5600 is a full-size liquid level float switch designed for demanding industrial and mechanical service environments. It features a 1/4 inch NPT threaded connection and stainless steel construction throughout — body, float, and stem — making it suitable for high-temperature, high-pressure, and corrosive liquid applications. The switch operates on SPST logic and is rated for 120 volts AC or 240 volts AC at up to 60 watts. With a maximum pressure rating of 200 psi and a maximum temperature rating of 200 degrees F, the M5600 handles conditions that standard float switches cannot. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers.

The M5600 is applied in systems where liquid level monitoring is required under elevated temperature, elevated pressure, or chemically aggressive conditions. Common installations include boiler feed systems, chemical process tanks, pressurized vessels, and high-temperature liquid reservoirs. The 2.13 inch float diameter and 0.55 specific gravity float rating allow the switch to function reliably across a range of liquid densities. This switch is appropriate for both commercial and light industrial systems where a compact, full-size float switch with NPT threaded entry is required.

Key Features

• All stainless steel construction — body, float, and stem — for corrosion resistance in aggressive media
• Rated to 200 psi maximum pressure and 200 degrees F maximum temperature
• 1/4 inch NPT threaded connection for standard pipe fitting integration
• SPST switching logic with dual voltage compatibility: 120 volts AC and 240 volts AC
• 0.55 float specific gravity rating suitable for water and similar density liquids
• Compact full-size switch format for pressurized tank and vessel installations

Compatibility

Designed as an OEM-style replacement or direct installation float switch for full-size liquid level switch applications requiring 1/4 inch NPT threaded entry, SPST switching, and stainless steel wetted materials in high-temperature, high-pressure, or corrosive service conditions.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified industrial maintenance technician. Depressurize and drain the system completely before removing or installing the switch, and verify that the system is de-energized before making any electrical connections. Consult applicable local mechanical and electrical codes, including NEC guidelines for wet-location wiring, prior to installation. Do not exceed the rated pressure or temperature limits of the switch under any operating condition.
