PLASTIC FLOAT SWITCHESVERTICAL-MOUNTING REED-TYPE FLOAT SWITCHESAPPROVEDMATERIAL765.130.1106911 HEAVY-DUTY SWITCHESFEATURES• Magnets in the float actuate a magneticswitch in the stem. So simple is the methodof converting mechanical motion into anelectrical signal that reliable service canbe expected for years. The switch can bethread-mounted from the top or bottom ofthe tank. The length can be extended bystandard pipe and fittings. The FDA-ratedmaterials are corrosion-resistant and impartno taste to food or beverages.• Molded of Kynar (tan), Acetal (red), orORDER INFORMATION:Polypropylene (gray PP body and blue PPfloat), this switch is well-suited to controllinglevels of water-based solutions at temperaturesof up to 190°F (90°C). The rugged 3-Ampswitch can be directly connected to solenoidvalves and motor switches. The switches areidentified, at the end of the stem, as:• WET OPEN—The switch opens as the floatapproaches the hex (threads); the contactcloses as the float approaches the stop ring.• DRY OPEN—The switch opens as the floatapproaches the stop ring; the contact closesas the float approaches the hex (threads).6911.420 FLOAT SWITCH, wet open, Polypro $155.976911.421 FLOAT SWITCH, dry open, Polypro 155.976911.440 FLOAT SWITCH, wet open, Kynar 526.396911.441 FLOAT SWITCH, dry open, Kynar 526.396910 MINIATURE SWITCHESFEATURES• Molded of FDA-rated Kynar PVDF (natural, unpigmented),Polypropylene (gray, blue, and black) or hydrocarbon- resistantacetal (red) for reliable operation without maintenance, theswitch functions include control of make-up water in foodsteamers, chemistry in automatic film-processing, coolantin molding machines, and hundreds of other equipmentapplications.• The switch can be mounted up or down, and can be changedfrom “normally open” to “normally closed” by removing theretaining ring and reversing the float. (It’s shipped with thefloat in the normally closed position.) The smooth surfacesare easy to keep clean, and the unit will switch small solenoidvalves and relays up to 0.080A (120 VAC).• For higher electrical loads, use a 6932 controllerfound on page 394.• The 6910 switch is recognized under the U/Lcomponent recognition program. A locknut formounting is included.765.130.120ORDER INFORMATION:6910.050 FLOAT SWITCH, Polypropylene $15.896910.250 FLOAT SWITCH, Kynar PVDF 35.47HORIZONTAL-MOUNTING REED-TYPE FLOAT SWITCHESFEATURES• For low-cost automatic control applications, these switchesare molded of FDA materials that are corrosion-resistantand impart no taste to food. The concept is simple: Whenthe float is moved toward the switch housing, it “clicks” on.When moved away, it “clicks” off. It can be installed througha bulkhead hole (0.562” clearance) from the “outside in” orfrom the “inside out.” It will switch small solenoid valves andrelays up to 0.080A (120VAC). For higher electrical loads, usea 6932 controller on page 414. These models are available inPolypropylene (gray), Kynar PVDF (natural), or Acetal (red).• The 6905 switches can be mounted directly through the tanksidewall or into the tank fitting. Simply rotate 180° for either“normally closed” or “normally open” operation.ORDER INFORMATION:6905.100 FLOAT SWITCH, Polypropylene $47.996905.400 FLOAT SWITCH, Kynar PVDF 170.57Vertical SwitchesHorizontal Switches6910.050Polypro6910.250Kynar6910.350Acetal6911.420/ .421Polypro6905.100Polypro6905.400Kynar6905.500AcetalThread NPT (small, large) (in.) 0.125 0.25 0.25, 0.5Hex, Body (in.) 0.5 1 1Length, Overall (in.) 2.1 4.5 5.12Float Diameter (in.) 1 2.06 0.7Max.
