Johnson Controls P266SNR-1 Pressure Transducer

For veteran technicians managing commercial refrigeration and HVAC systems, the Johnson Controls P266SNR-1 is a critical component for precise head pressure control. This electronic pressure transducer is engineered specifically for use with the P266 series condenser fan speed control, ensuring seamless refrigerant pressure monitoring within a designated 0 to 508 psi (0 to 35 bar) range. Built as a high-durability, stainless steel remote-mount sensor, it provides the 5 VDC ratiometric signal necessary for the P266 controller to modulate motor speed on permanent split-capacitor (PSC) motors. This specialized HVAC pressure sensor is cross-compatible and identical to the P266SNR-1C model, allowing for straightforward replacement in existing condenser fan speed setups. Featuring a 1/4" SAE female flare connection and a 2-meter (6.6-foot) shielded cable, it offers the reach and secure fit required for rugged, weather-resistant outdoor refrigeration pressure transducer applications, replacing legacy P66 and P215 series hardware with improved efficiency and response time.

Key Benefits:

• Broad Compatibility: Direct replacement for the P266SNR-1C, integrating perfectly with P266 series digital controllers.
• Heavy-Duty Construction: Features a stainless steel sensing element for 100% compatibility with non-corrosive and A2L/A3 refrigerants.
• Precise Signal Output: Delivers a reliable 0.5 to 4.5 VDC ratiometric signal for accurate condenser pressure management.
• Simplified Installation: Standard 1/4" SAE female flare connection ensures a leak-proof fit on most liquid or suction line service ports.
• Enhanced Durability: Rated for ambient operating temperatures from -40?F to 140?F, ideal for harsh rooftop environments.

Common Questions:

Can I use a P266SNR-1 to replace a P266SNR-1C?
Yes, these two part numbers represent the same technical specifications and are fully interchangeable in all P266 control applications.

What is the difference between the SNR-1 and SNR-2 models?
The P266SNR-1 is rated for 0 to 508 psi, whereas the SNR-2 model is designed for higher pressure applications up to 754 psi. Always verify your system's maximum operating pressure before selection.

Does this transducer require a separate power supply?
No, it is powered directly via the 5 VDC source provided by the P266 series fan speed control unit through its 2-meter connection cable.
