SOR 4NN-K2-N4-BIA Pressure Switch

SOR 4NN-K2-N4-BIA Weatherproof Pressure Switch is a rugged, industrial‑grade switch in SOR’s 4NN family that activates or deactivates electrical circuits based on sensed pressure, housed in a weatherproof enclosure for durable operation in demanding environments. The 4NN family uses standard wetted parts that are normally suitable for air, oil, and water, making it a versatile option for a range of process and equipment applications. Variants in this family—such as the 4NN-K2-N4-BIA-TT, which carries a pressure range of 14–55 kPa, and closely related models like 4NN-K2-N4-B1A—illustrate the configurability of these devices. Distributors list the 4NN-K2-N4-BIA alongside other 4NN configurations, confirming it as part of the same product line.
