SOR 5NN-K3-S1-F1A-CSX Pressure Switch

SOR 5NN-K3-S1-F1A-CSX Pressure Switch is a 5NN-series pivot-seal pressure switch from SOR Inc. designed for automatic control of pressurized air and non‑corrosive fluids within a 25 to 240 psi setpoint range. It features a 1/4" NPT(F) pressure port and uses a K-design switching element with an F1A diaphragm configuration; the sensing mechanism is a piston-on-diaphragm construction. The typical dead band for this family runs about 2.2 psi. The K-design variants employ low-power gold-contact switching and are rated for AC operation up to 250 VAC at 15 A, making them suitable for integration into standard industrial control circuits.
