WNS-C102X Differential Pressure Switch | SPDT | 0.03–0.2 MPa | HVAC & Refrigeration

Precision Differential Pressure Regulation for Critical Systems

The WNS-C102X Differential Pressure Switch is a high-accuracy Japanese-made instrument designed for applications where the balance between two pressures is crucial for system performance. Commonly used in HVAC systems, ammonia handling, marine setups, and refrigeration, this SPDT (Single-Pole, Double-Throw) switch responds quickly to pressure differential changes to activate or deactivate electrical controls.

With an adjustable range of 0.03–0.2 MPa and factory settings ideal for standard operating thresholds, the WNS-C102X ensures reliable operation across water, air, or fluorinated refrigerant systems. A drip-proof enclosure is available for marine use, and an explosion-proof version is also offered for hazardous environments (upon request). Its compact, IP20-rated enclosure, durable construction, and standard mounting bracket make installation seamless in both new and retrofit systems.
