Frequently Asked Questions

• Q: What is the maximum wall thickness for this 23.5 inch housing?
  A: With 23.5 inch penetration, maximum wall thickness is approximately 22.5 inches (572 mm). Calculation: 23.5in minus 0.5in minimum thread engagement minus 0.06in gap minus 0.44in safety margin. This is the longest standard penetration available.
• Q: Is the probe already installed in this housing?
  A: Yes. Option 28 means the 3300 XL 8mm probe is included and factory installed. The probe has multiple approvals (CSA/ATEX/IECEx) for hazardous locations.
• Q: What is the probe cable length?
  A: The probe has a 1.0 meter (3.3 feet) cable. This provides flexibility for proximitor mounting. Extension cables can be added to reach 5m or 9m total system length.
• Q: Why no fittings included with option 00?
  A: Option 00 means without fittings. For this long penetration housing, you may need custom conduit adapters. Order fittings separately based on your specific cable entry requirements.
• Q: Can this housing withstand internal pressure?
  A: No. The plastic housing is certified for NEMA 4X and IP66 (external water protection) but is not designed to resist internal or external pressure. For pressurized applications with long penetrations, contact Bently Nevada about custom designs.
