Industrial 4NN-K5-N4-C1A Pressure Switch

Industrial 4NN-K5-N4-C1A Pressure Switch from SOR is an adjustable, industrial‑grade device that detects pressure in a system and actuates a circuit when the setpoint is reached, enabling automated control of pumps, compressors, and hydraulic lines. The model 4NN-K5-N4-C1A carries an adjustable pressure range of 3 to 50 psi, allowing precise thresholding across a variety of applications. The N4 in the designation signals non‑hazardous‑location use, aligning with SOR’s family of switches designed for standard industrial service. Basic SOR switches in this line use wetted parts rated for common fluids and are typically suitable for air, oil, and water service, making the 4NN-K5-N4-C1A a versatile option for many equipment packages. With its field‑adjustable setpoint and repeatable actuation around the cut‑in and cut‑out pressures, it supports reliable start/stop control and helps minimize nuisance cycling in automatic pressure‑control loops. For exact electrical ratings, mounting, and termination details, refer to the official SOR catalog or the specific 4NN‑K5‑N4‑C1A datasheet from SORInc.
