Johnson Controls P100DA-2C Pressure Switch

The Johnson Controls P100DA-2C Pressure Switch is a non-adjustable, encapsulated, direct-mount device engineered for reliable pressure control in refrigeration and HVAC systems. With a rugged SPST output and a compact footprint, this switch simplifies installation in tight panels while delivering consistent protection against overpressure, enhancing system safety and long-term durability in demanding environments.

Designed for versatile applications, the P100DA-2C supports critical control points such as low-limit and high-limit protection, fan cycling, and safety interlocks. The encapsulated design guards against moisture, dust, and contaminants, making it suitable for ice machines, food service equipment, refrigeration units, and air conditioning systems. Direct-mount installation speeds service and reduces wiring complexity, while UL approvals for US and Canada ensure trusted performance in commercial settings.

Key specifications are purpose-built for reliable operation in busy control rooms, delivering precise switching under demanding loads and providing quick, easy field replacement when maintenance is required.
