Industrial 721K2-N-P6-C-FM Ultrasonic Point Level Switch

The 721K2-N-P6-C-FM Ultrasonic Point Level Switch from SOR Controls Group is a compact, single-point level sensor that uses a metal-notch integral sensor to detect liquid height and drive a DPDT relay. It provides a DPDT output rated for up to 250 VAC at 10 A, with a maximum switching load of 30 VDC, enabling independent signaling of two circuits or interlock control without external interface components. The K2 configuration denotes a metal notch integral sensor and this FM-certified model is designed for hazardous-location environments, making it suitable for process vessels in chemical handling, water treatment, and bulk liquid applications. As part of SOR’s 721 family of ultrasonic level switches, the unit is built for reliable operation in demanding industrial settings and supports straightforward integration into existing control schemes to trigger pumps, alarms, or logic based on a defined level threshold.
