It works by sensing the resistance between two or three probe electrodes — when the liquid bridges the probes, the internal relay switches. The adjustable sensitivity from 0 to 5 MOhm means you can tune it for different liquid conductivities, from clean water (low resistance) to demineralized or high-purity water (high resistance) or even some process chemicals. It runs on a 115 VAC supply and switches a SPDT (2 Form C) relay rated at 5 A at 220 VAC — enough to drive a small pump contactor or an alarm annunciator directly. The octal 8-pin base (standard 8-pin relay footprint) makes it a drop-in swap for existing level relay sockets in a panel. Socketable design — mounts on a standard 8-pin octal relay socket (sold separately). That socket typically snaps onto DIN rail or panel-mounts with two screws. The plug-in form factor means you can swap the controller in seconds without disturbing the wiring; the base stays in the panel. Not rated for outdoor or washdown locations without an IP-rated enclosure around it. Listed as active in production. This is a mature, widely stocked part in the 61F series — not a niche or end-of-life item. That means it's a safe choice for a BOM that needs to stay stable for the next several years.","metaTitle":"Omron 61F-HSL AC115 Level Controller, 115VAC, SPDT, Adjustab","metaDescription":"Omron 61F-HSL AC115 high/low level controller. 115VAC supply, SPDT relay output, adjustable sensitivity 0-5 MOhm.

Set it low (near 0) for conductive liquids like tap water; set it high (up to 5 MOhm) for low-conductivity liquids like deionized water or certain chemicals. Turn the potentiometer until the relay just switches with the probe submerged."},{"question":"What is the 61F-HSL AC115's output type and contact rating?","answer":"It has a SPDT (2 Form C) relay output rated at 5 A at 220 VAC. That's one normally-open and one normally-closed contact set per Form C, giving you two independent switching channels."},{"question":"What socket does the 61F-HSL AC115 plug into?","answer":"It uses a standard 8-pin octal relay socket (sometimes called a 'round base' or 'octal base'). The pinout matches common Omron and industry-standard 8-pin relay bases.
