Industrial 711K1-N-P6-C Single Point Level Switch

The SOR 711K1-N-P6-C Single Point Ultrasonic Level Switch is an industrial sensor that provides a discrete, single-point level decision for liquids in tanks and vessels. The device uses ultrasonic sensing to detect when the liquid reaches a preset level and triggers a dry-contact output, suitable for pump control and level alarms in process applications. The model designation 711K1-N-P6-C indicates a 1-point, metal notch integral sensor configuration in the 711 family, with a standard contact rating of 250 VAC at 5 A and a DC load rating of up to 30 VDC. This compact unit combines the sensing element with the control electronics for straightforward installation in typical industrial environments and reliable performance in common process liquids. Common applications include high/low level control in process tanks, sumps, reactors, and piping systems, where an automatic control action or alarm is required when liquid reaches a defined level. The 711K1-N-P6-C is part of SOR's Ultrasonic Point Level Switch lineup (alongside models in the 701 and 721 series), offering robust point-level sensing with minimal maintenance for industrial automation tasks.
