Frequently Asked Questions

• Q: What is the total tip reach with this configuration?
  A: Standoff (2.0in) + Probe Penetration (11.0in) = 13.0 inches from mounting surface to probe tip. This reaches through thick walls with a moderate standoff for recessed ports.
• Q: When should I use a 2 inch standoff?
  A: Use 2 inch standoff for slightly recessed mounting ports or when you need minimal clearance from obstructions. It provides enough space for tool access without excessive extension.
• 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.
