Madison M5600-PR Liquid Level Switch 750 Psi 1/4 Npt

Product Description

The MADISON M5600-PR is a full size liquid level switch designed for monitoring and controlling fluid levels in industrial and commercial piping systems. This switch features a 1/4 inch NPT threaded connection with dual contact logic, offering both normally open (N.O.) and normally closed (N.C.) operation in a single unit. Rated for a maximum working pressure of 750 psi and an operating temperature range of -40 degrees F to 392 degrees F, the M5600-PR handles demanding service conditions. It is installed by licensed plumbers, HVAC technicians, and industrial maintenance professionals where reliable float-based level sensing is required.

The M5600-PR is suited for use in tanks, vessels, and piping systems that require liquid level detection across a wide range of temperatures and pressures. Its wet contact type makes it appropriate for direct immersion in compatible liquids. The 2.05 inch body diameter and standard NPT thread sizing allow for straightforward integration into new or existing installations in both commercial and light industrial environments. Typical applications include sump monitoring, condensate management, boiler feed systems, and process fluid control.

Key Features

• Dual contact logic: N.O. and N.C. operation for flexible circuit integration
• Maximum working pressure of 750 psi for high-demand service conditions
• Wide operating temperature range: -40 degrees F to 392 degrees F
• 1/4 inch NPT threaded connection for standard pipe fitting compatibility
• Wet contact type rated for direct liquid immersion

Compatibility

Designed as an OEM-style replacement or new-installation liquid level switch for commercial and industrial systems utilizing 1/4 inch NPT threaded ports and requiring N.O. or N.C. float switch logic.

Installation Notes

Installation should be performed by a qualified plumber or licensed mechanical technician familiar with pressurized piping systems. Shut off and depressurize the system completely and drain fluid from the affected section before removing or installing the switch. NPT threaded connections should be made with appropriate thread sealant rated for the fluid and temperature range of the application. Verify contact logic (N.O. or N.C.) matches the control circuit requirements before energizing the system.
