SERIES F6 & F7
LEVEL SWITCHES - VERTICAL
LEVEL
Low Cost, Reliable and Compact, Hermetically Sealed Contacts
F7-SB F7-ST713
The Series F6 & F7 Vertical Level Switches are designed to be mounted at the
maximum or minimum level point to provide level indication and control. Models are
shipped with normally open switch contacts which close as the oat rises toward the
mounting threads.
BENEFITS/FEATURES
• Simple installation with low cost and reliable design
• Flexible application design with open or close circuits for rising or falling levels with
vertical models that mount internally, oriented within 30° of vertical, or select
optional ttings for external mounting
• Long product life from hermetically sealed reed switches that are actuated by
magnets permanently bonded inside the oat arm
• Switch ratings are suitable for many solid state control systems and monitors or
alarms
• Variety of application use with high current, simple relay interfaces
