Cleveland Controls NS2-0206-00 Pressure Switch

The Cleveland Controls NS2-0206-00 is an industrial-grade air flow pressure sensing switch designed for precision in low-pressure applications. Factory-calibrated to a .12" WC set point, this unit serves as the direct replacement for RSS-495-206. Built with a sturdy, glass-filled polycarbonate housing and a silicone diaphragm, it ensures high accuracy and reliability in demanding environments. The integral snap-acting switch mechanism is actuated by positive, negative, or differential air pressure, providing a narrow switching differential essential for safety and system control. This OEM pressure sensing switch features color-coded ports—black for positive (P1) and gray for negative (P2)—for simplified identification during field installation. It utilizes 1/8" NPT female pressure connections and 90° male quick-connect electrical terminals, making it a versatile HVAC pressure switch for residential and light commercial equipment including furnaces and boilers from brands like Armstrong, Bard, and Friedrich.

• Direct Cross-Reference: Specifically engineered to replace the RSS-495-206 without requiring field recalibration.
• Durable Construction: Glass-filled polycarbonate body offers superior stability across an operating temperature range of -40°F to 180°F.
• Accurate Sensing: Maintains a tight set point tolerance, detecting minute changes in air flow to protect critical heating components.
• Versatile Application: Capable of sensing positive, negative, or differential pressure for diverse manifold and inducer configurations.
• Simplified Wiring: Equipped with standard 1/4" male spade terminals for quick integration into existing control circuits.

Is the NS2-0206-00 field adjustable?
No, this model features a factory-calibrated set point of 0.12" WC. For applications requiring different tolerances, the set point is fixed to ensure consistent safety performance as per OEM specifications.

Which ports should be used for a negative pressure application?
For negative pressure (vacuum) sensing, connect the sample line to the gray (P2) port and leave the black (P1) port open to the atmosphere.

What media is this switch compatible with?
It is designed for air and combustion by-products that do not degrade silicone or polycarbonate, making it ideal for HVACR pressure sensing in vent and flue systems.
