The SOR 4NN-K5-N1-B1A-PP Pressure Switch is a 3–50 psi adjustable switch from SOR’s 4NN family, designed to energize or de-energize electrical circuits when process pressure crosses the setpoint. The K5 suffix defines the specific preset profile within the 4NN line, while B1A-PP signals the standard enclosure/configuration used in many industrial installations. In typical process automation, this compact switch is used to control pumps, compressors, or hydraulic circuits, providing a reliable, field-adjustable actuation point in environments that match the 3–50 psi operating window.
