Frequently Asked Questions
Q1: What is the difference between AZ52 and AZ51 connectors?
A: AZ52 uses a set screw to grip unthreaded EMT, making installation faster and easier. AZ51 uses female NPT threads to connect threaded EMT conduit. AZ52 is ideal when you need quick installation without threading.
Q2: Can AZ52 be used in outdoor applications?
A: AZ52 has an IP40 rating, which is suitable for dry indoor environments. For outdoor or wet locations, consider AZ50 or AZ51 connectors with IP64 rating.
Q3: What tools are needed to install AZ52?
A: You only need a standard wrench or screwdriver to tighten the set screw. No threading equipment required, which saves time and reduces installation costs.
Q4: Which liquid tight conduits are compatible with AZ52?
A: AZ52 is compatible with PLTG13PVC and PLTG23PVC series liquid tight flexible metal conduits. Check the parameter table for specific size matching.
Q5: Is the set screw connection reliable for industrial use?
A: Yes, when properly tightened, the set screw provides a secure mechanical connection suitable for industrial applications. The zinc alloy construction ensures long-term durability.
Q6: What is the maximum temperature AZ52 can withstand?
A: AZ52 connectors are rated for operation from -20℃ to +90℃, suitable for most industrial environments including HVAC systems and manufacturing facilities.
