Frequently Asked Questions

• Q: What is a standoff adapter and when do I need it?
  A: A standoff adapter extends the housing away from the mounting surface. Use it for recessed mounting ports, to clear obstructions, for thermal isolation from hot surfaces, or to improve tool access during installation.
• Q: What is the total tip reach with this standoff?
  A: Standoff (7.0in) + Probe Penetration (6.6in) = 13.6 inches from mounting surface to probe tip. This reaches through very thick walls or deep recessed ports.
• 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 0.5 meter (20 inch) cable. This short cable is ideal when the proximitor mounts near the housing. Extension cables can be added to reach 5m or 9m total system length.
• 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, contact Bently Nevada about custom designs.
