FH Series Horizontal Float Switches
Quick Overview
The FH Series horizontal float switch mounts through the side wall of a tank, reservoir, or vessel. As the liquid level reaches the switch point, a buoyant float pivots upward and the permanent magnet inside actuates the hermetically sealed reed switch. The compact horizontal profile allows installation where vertical stem clearance is unavailable — sump pits, wall panels, and low-profile vessels. Available in stainless steel (303, 304, 316L) and a wide range of engineering plastics including polypropylene, PVDF, Kynar, and nylon.

Key Features
Compact Side-Mount Profile
Horizontal orientation fits installations where vertical clearance is limited — sump walls, side of tanks, and confined vessels.
Magnetic Reed Technology
Float contains a permanent magnet that actuates a hermetically sealed reed switch inside the stem — no fluid contact with switch electronics.

Stainless steel 303, 304, or 316L; polypropylene; PVDF; Kynar; and nylon housings to match your fluid and environment.
Custom Cable Lengths
Standard and custom cable lengths with a variety of connector and termination options for OEM and panel integration.
SPST and SPDT Options
Choose normally open or normally closed SPST, or change-over SPDT for flexible control logic without external relays.
OEM Volume Pricing
Designed for production OEM quantities with short lead times and custom packaging available.
