Cleveland Controls NS2-0505-00 Pressure Switch

The Cleveland Controls NS2-0505-00 Pressure Switch is a high-performance air pressure sensing switch designed for critical monitoring of positive, negative, or differential pressure in HVACR and industrial pneumatic systems. Built with a rugged, glass-filled polycarbonate housing and a high-stability silicone diaphragm, this V-120 air pressure switch ensures precise set point accuracy even in demanding environments. It features a manual reset mechanism and is encapsulated in a NEMA 4X enclosure, providing superior resistance against dust, moisture, and corrosion. For contractors, the color-coded ports—black for positive and gray for negative—simplify the air pressure switch installation process. This NS2 series pressure switch utilizes an integral snap-acting switch to provide reliable electrical switching across a wide temperature range of -40°F to 190°F. With its compact footprint and universal mounting flexibility, the NS2-0505-00 is a standard field replacement for maintaining industrial pressure switch safety protocols and system efficiency.

• NEMA 4X Enclosure: Provides robust protection for internal components against harsh environmental contaminants and moisture.
• Precise Pressure Regulation: Features a narrow switching differential and low set point tolerance for mission-critical sensing.
• Simplified Installation: Color-coded sample line connectors and 1/4 inch male quick-connect terminals allow for fast field wiring.
• Durable Construction: Engineered with a glass-filled polycarbonate body and silicone diaphragm for a long service life exceeding 100,000 cycles.
• Versatile Sensing: Capable of monitoring positive, vacuum, or differential air pressure in a variety of pneumatic applications.

How do I identify the high and low pressure ports?
The ports are color-coded for fast identification: the black port is for positive (P1) pressure, and the gray port is for negative (P2) or vacuum pressure.

Can this switch be mounted in any orientation?
For peak accuracy, the switch should be mounted with the diaphragm in a vertical plane. Avoid mounting locations prone to high vibration or with sample line connectors pointing upward where moisture could collect.

Is this switch compatible with combustion by-products?
Yes, the silicone diaphragm and polycarbonate body are designed to handle air and typical products of combustion that do not degrade these materials.
