Endress+Hauser FTL50-JHN20 Switch | Capacitive, Level, Solid/Liquid, 316L, 2-Wire, 24V DC
Endress+Hauser FTL50-JHN20 level switch specifications. Capacitive sensor, 2-wire, 24V DC, 316L, for high/low level detection.
Product Overview
The Endress+Hauser FTL50-JHN20 is a capacitive level switch designed for point level detection of liquids, pastes, and bulk solids. It features a 316L stainless steel sensor rod, operates on a 24V DC, 2-wire loop, and provides a switching signal (PNP/NPN) for alarm or control functions. Its adjustable sensitivity and robust design make it suitable for detecting a wide range of media, including conductive and non-conductive materials, in tanks, silos, and hoppers.
