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 easy wiring. at the end of March 2018. Select from three mounting methods: JEM, DIN rail mounting, or screw mounting. Note: LED operation indicator is provided on Controllers manufactured in August 1999 or later.

Subclassified into 2 km and 4 km models according to the model of relay unit used. Specify 2 km or 4 km when ordering. 3. When ordering, specify the desired operating voltage at the end of the model number. Example: 61F-GN 110/220 VAC Desired supply voltage 4. Contact your OMRON representative for products with voltages other than those listed above. 5. If you order with a standard model number, the corresponding Relay Units are also delivered as part of a set. If you order the 61F-GN, one 61F-11 Relay Unit is included in the set. * 61F-G N (120/240 VAC) in this catalog have been discontinued at the end of March 2018. 2
