OMRON AUTOMATION 61F-G2NAC100/200

Floatless Level Switch (Compact Type) 61F-G@N CSM_61F-G_N_DS_E_3_3 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 easy wiring. Select from three mounting me thods: JEM, DIN rail mounting, or screw mounting. Note: LED operation indicator is provided on Controllers manufactured in August 1999 or later.
