Product Summary
The SOR 107AL-N12-P1-F0A-X is a rugged instrument for low differential pressure detection. It uses a large-area diaphragm for precise readings. This switch is ideal for HVAC draft ranges and burner management systems. It provides a reliable signal for critical air and gas services. Its robust design ensures long-term performance in industrial settings.
Product Procurement & Buyer Guide
Why Choose the 107AL-N12-P1-F0A-X?
Procurement engineers need a switch that matches the exact application environment. The 107AL-N12-P1-F0A-X offers a Weathertight NEMA 4 housing made from 6063-T5 aluminum. This material resists corrosion and protects internal components from moisture and dust. This feature makes it perfect for indoor and sheltered outdoor installations.
This model provides an SPDT snap-action switching element. This element is both UL Listed and CSA Certified. These certifications guarantee high repeatability and a narrow dead band. You can trust the switch to actuate accurately at the set point every time. This precision reduces false alarms and improves system efficiency.
Technical Specifications for Engineers
The unit features a fine external set point adjustment with a visual scale. This simplifies calibration during commissioning or process changes. You can quickly verify the set point without removing the cover. This saves valuable maintenance time.
The pressure ports use plated cold-rolled steel with 1/8” NPT(F) connections. Wetted materials include Buna-N, brass, aluminum, and stainless steel. The switch handles a maximum system pressure of 10 psig (.69 bar). It is also vacuum protected to 30” Hg.
Comparative Analysis & Alternative Matrix
Comparing N12 and N40 Model Variants
We compare the 107AL-N12-P1-F0A-X to the 107AL-N40-P1-F0A-X to highlight key differences. The N12 model uses a Weathertight NEMA 4 aluminum housing. The N40 model uses a cast iron housing with a hermetically sealed switching element. The N40 version is certified as explosion-proof for hazardous locations.
The electrical connection also differs between these two models. The N12 version uses a 3/4” NPT(F) conduit entry with screw terminals. The N40 version uses a 1/2” NPT(M) connection with 18” wire leads. Choose the N12 for standard weathertight applications. Select the N40 for explosive gas or dust environments.
Both models share the same pressure port size and wetted materials. They also have identical temperature limits of -40 to 150°F (-40 to 65°C). Each unit weighs approximately 5 lb (2.3 kg). The N12 has SPDT screw terminals. The N40 has an SPDT switch with contact ratings up to 5 amps.
Application-Specific Configuration
The 107AL-N12-P1-F0A-X is built for HVAC and burner management systems. It monitors draft pressure in boilers and furnaces. It also suits other industrial air and gas services. Ensure the media is compatible with the wetted materials list.
For a different port size, you can order the F1A suffix. This changes the connection from 1/8” NPT(F) to 1/4” NPT(F). Always verify the process media and environmental conditions before ordering. This ensures the switch will perform reliably for its entire service life.
