Stainless Steel Horizontal Float Switch

FS-500

Long Lasting, Dependable Performance

With stainless steel wetted materials, reversible switch orientation, and CSA & NSF 169 certifications, FS-500 switches are go-anywhere, use-everywhere horizontal float switches.

Description

Three Mounting Options
Choose from dual 1/2" NPTMs, 1/2" NPTM and 1/4" NPTM, or Bulkhead mount with 1/2 - 13 threads.

CSA and NSF Approvals
Standard Temperature, dual-NPTM mount switches are CSA Explosion Proof, while all Bulkhead mount switches and all High Temperature models are approved for General Use. Every FS-500 is NSF 169.

100W Switching Capacity
FS-500 switches are rated for 100W resistive loads, at up to 120 VDC or 240 VAC.

Common Applications
  • C I, D1 Hazardous Locations
  • Food / Beverage
  • Chemical
  • Water / Wastewater
