Floatless Level Switch (Compact Type)
61F-G@N
CSM_61F-G_N_DS_E_3_5
Improved Design for a More Lightweight
Construction and Reduced Standby Power
Consumption.
Standby power reduced to 85% or less of previous models.
(Applicable to 61F-GN.)
Weighs only 85% or less of previous models. (Applicable to
61F-G3N/-G4N.)
Easy identification of operating status with LED operation
indicator.
Increased reliability of internal relay (micro load: 5 VDC, 1 mA)
to enable PLC input.
Electrode terminals and other wiring terminals are separated for
61F-G@N (120/240 VAC) in this catalog have been discontinued
