The Omron 61F-HSL AC24 is a High/Low Level controller from the 61F series, operating on a 24VAC supply. Adjustable sensitivity from 0 to 5 MΩ lets you tune the detection threshold for conductive liquids — useful when the fluid conductivity varies or when you need to ignore foam or sludge buildup. The SPDT (2 Form C) relay output switches loads up to 5A at 220VAC, so it can drive a small pump contactor or alarm directly.
Integration Notes
Socketable via an 8-pin octal base — common in panel builds, easy to swap without rewiring. The plug-in termination style (8-pin octal) mates with standard relay sockets, so retrofitting into an existing panel takes minutes.
