SOR 5NN-K5-N4-F1A Pressure Switch

SOR 5NN-K5-N4-F1A Pressure Switch is an industrial‑grade sensing device from SOR Inc. that automatically opens or closes electrical contacts when a preset pressure is reached, enabling automatic control of pumps, compressors, and safety interlocks in pneumatic or hydraulic systems. This NN‑series model is designed for rugged environments and is cataloged under the SOR pressure‑switch family, reflecting a configuration that supports field‑adjustable actuation within a defined pressure window. A retailer listing for the 5NN-K5-N4-F1A‑PP variant indicates an adjustable pressure range of 35–375 psi with a 1500 psi over‑range, making it suitable for applications that require a relatively wide actuation window and a generous safety margin. Common uses include triggering control circuits in air compressors, hydraulic pumps, and processing equipment where precise pressure thresholds are essential for reliable protection and automation. The NN family is described in SOR literature as employing a force‑balanced, piston‑actuated mechanism with a diaphragm‑sealed sensing element, which contributes to stable operation across multiple cycles and varying conditions. With the K5‑N4‑F1A configuration, this model embodies a specific electrical and enclosure arrangement within the SOR lineup, offering a robust solution for industrial pressure monitoring and interlock applications.
