Product Description
The Omron Automation 61F-HSL is a high-sensitivity floatless level switch for liquid-level control in tanks, containers, and pipelines, triggering actions based on liquid levels. It detects poorly conductive substances like ice, pure water steam, and humidity. It operates on 24V AC, 100V AC, 110V AC, 200V AC, or 220V AC at 50/60 Hz, with an 85-110% rated voltage range. Its interelectrode voltage is 13V DC (max), current is 1mA DC (max), and operate resistance ranges from 0 to 5 M. The control output handles 2A at 220VAC (inductive) or 5A at 220VAC (resistive). It operates from -10 to 55C with 45-85% humidity, has 100 M insulation resistance at 500V DC, and 2,000V AC dielectric strength at 50/60 Hz for 1 minute. Its electrical life is 50,000 operations (min) and mechanical life is 5,000,000 operations (min).
Is Your Device Showing These Signs?
The Omron 61F-HSL floatless level controller commonly experiences failures due to corrosion of the electrodes, leading to inaccurate liquid level sensing and erratic pump operation. Technicians address this by replacing corroded electrodes and verifying proper wiring connections to the controller. Component degradation within the 61F-HSL control unit, specifically capacitor failures on the power supply board, causes intermittent operation or complete failure; component-level repair or full unit replacement resolves this. Furthermore, improper grounding of the system introduces noise and interference, resulting in false triggering; ensure a dedicated earth ground to mitigate this issue.
Technical specifications
The Omron 61F-HSL is a floatless level switch for liquid-level control, detecting poorly conductive substances. It operates on various AC voltages, with specific interelectrode voltage/current and operate resistance. The control output handles 2A/5A at 220VAC (inductive/resistive). It functions in -10-55C with specified humidity, insulation resistance, and dielectric strength, offering a minimum electrical/mechanical life of 50,000/5,000,000 operations.
