APG FS-410 Explosion Proof Miniature Stainless Steel Vertical Float Switch

Description The FS-410-S switches are CSA Explosion Proof certified, while the FS-410-HT variants are CSA General Use approved. NSF 169 certification is included with all FS-410 switches. With a total length of fewer than 2.35 inches (60 mm) and an all-stainless steel structure that withstands temperatures of up to 500° F, the series FS-410 float switch provides great performance to compact places. The FS-410-S operates between -40° and 368° F (-40° to 187° C), whereas the FS-410-HT operates between -40° and 500° F (-40° to 260° C). Features: Class I Division 1 / 2 Class II Division 1 / 2 Class III NEMA 4x NSF 169 certified Extremely compact size Reliability / long switch life Shock resistive construction Switch rated for 100 W Can be used in a wide range of liquids Operating temperatures up to 500° F (260° C) CSA Explosion Proof (Standard Temp) and General Use (High Temp) Vertical mounting 316L SS material Made in the USA Versions FS-410-S-24 SS Stem and Float, Standard Temp., 0.7 SG, 1/8″ NPTM, 24″ Wires FS-410-HT-24 SS Stem and Float, High Temp., 0.7 SG, 1/8″ NPTM, 24″ Wires FS-410-S-48 SS Stem and Float, Standard Temp., 0.7 SG, 1/8″ NPTM, 48″ Wires FS-410-HT-48 SS Stem and Float, High Temp., 0.7 SG, 1/8″ NPTM, 48″ Wires   Small Package From the top of the mounting threads to the bottom of the stem, the FS-410 is less than 2.35″ long, and the float is just under 1.2″ wide. Temperature Ranges The FS-410-S has an operating temperature range of -40° to 368° F (-40° to 187° C), and the FS-410-HT extends that range to -40° to 500° F (-40° to 260° C). Certifications FS-410-S switches carry CSA Explosion Proof certifications, while FS-410-HT models are certified for General Use. All FS-410 switches are NSF 169 certified. User Reversible Operation FS-410 float switches come standard with Normally Open operation. The e-clip at the bottom of the stem is easily removed to change to orientation of the float, changing the switch operation to Normally Closed.
