• Probe Cable Length: 1.0 meter (3.3 feet)
• Probe Approvals: Multiple (CSA/ATEX/IECEx)
• Probe Type: Eddy current proximity probe
• Pre-installed: Probe fitted in housing at factory

Materials

• Housing: Glass-reinforced PPS thermoplastic with conductive fibers
• Sleeve & Retaining Chain: AISI 304 stainless steel
• Outer Sleeve & Exterior Screws: AISI 303 stainless steel
• O-Ring: Neoprene for environmental sealing
• Probe Seal: Viton O-ring internal to probe case

Mechanical Strength

• Load Capacity: Supports 912 N (205 lb) at 38mm from unsupported end
• Impact Resistance (BASEEFA): Two separate 4 Joule impacts at -39°C and +115°C

Frequently Asked Questions

• Q: What is the maximum wall thickness for this 1.7 inch housing?
  A: With 1.7 inch penetration, maximum wall thickness is approximately 0.6 inches (15 mm). This is the shortest standard penetration available. Use only on very thin casings or with surface mount adapters.
• Q: Why choose such a short penetration housing?
  A: Ultra-short penetration minimizes probe extension, reduces risk of damage, improves rigidity, and fits in extremely tight spaces. It is ideal for thin-walled machinery or when using adapter plates.
• 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. Extension cables can be added to reach 5m or 9m total system length. The 1m cable provides flexibility without excess 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.
