Product Overview
The SOR 107AL-N12-P1-F0A-X is a 107 Low Differential Pressure Switch designed for precise monitoring and control of low differential pressures in HVAC, burner management, and industrial air and gas systems. Built to high-quality standards, this switch from SOR delivers exceptional reliability and performance in demanding environments.
Featuring a weathertight NEMA 4 electrical housing made from 6063-T5 aluminum, the SOR 107AL-N12-P1-F0A-X withstands harsh conditions while providing a secure enclosure for the switching elements. The pressure ports are constructed from plated cold-rolled steel for durability and corrosion resistance.
Key Features
- External set point adjustment with visual scale for easy calibration
- Fine set point resolution for accurate pressure control
- Narrow dead band ensures minimal hysteresis
- High repeatability for consistent performance over time
- UL Listed and CSA Certified snap-action switching elements
- Screw terminals standard on weathertight switches
Industry Applications
The SOR 107AL-N12-P1-F0A-X is ideally suited for draft ranges commonly associated with HVAC applications and burner management systems. It also serves other industrial air and gas services compatible with its wetted materials, which include Buna-N, brass, aluminum, cork, stainless steel, acrylic tubing, nylon, and plated cold-rolled steel.
In HVAC systems, this differential pressure switch monitors filter clogging, fan status, and duct pressure differentials. For burner management, it ensures proper air/fuel ratios and safety shutdowns. The rugged design minimizes downtime, offering long-term cost savings and improved operational efficiency.
Installation & Setup Guidance
When installing the SOR 107AL-N12-P1-F0A-X, mount the switch in a location that avoids excessive vibration and extreme temperatures. The electrical connection accepts 3/4" NPT(F) conduit with screw terminals for secure wiring. For the pressure ports, use 1/8" NPT(F) connections; if 1/4" NPT(F) is required, select a model with the F1A suffix instead of F0A.
Ensure the ambient and process temperature limits are respected (−40 to 150°F / −40 to 65°C) and that the maximum system pressure does not exceed 10 psig (0.69 bar). The switch is vacuum protected to 30" Hg, suitable for low-pressure applications.
Maintenance & Reliability
Routine inspection of the SOR 107AL-N12-P1-F0A-X should focus on the condition of the enclosure seal and the cleanliness of the pressure ports. The weathertight NEMA 4 housing protects internal components from moisture and dust, reducing maintenance frequency. The snap-action switching elements provide reliable operation under repeated cycling, contributing to a long service life and minimizing total cost of ownership.
Selection Guide & Purchasing Advice
Before purchasing the SOR 107AL-N12-P1-F0A-X, verify the process media compatibility with the wetted materials list and confirm the required pressure connection size. For applications needing a 1/4" NPT pressure port, order the F1A variant. The standard 3/4" NPT electrical connection suits most installations.
