21000-34-10-00-039-03-02 Bently Nevada Proximity Probe Housing Assemblies

• The assembly integrates a 3300 XL 8 mm reverse mount probe with connector protector. This probe supports selectable hazardous area approvals, ensuring flexibility in global installations.
• We include a 1.0 m probe cable permanently attached to the sensor. The longer cable length simplifies connections to remote monitoring systems without requiring junction boxes.
• This configuration uses no standoff adapter (00). The probe mounts directly, reducing part count and simplifying installation in tight spaces.
• Probe penetration measures exactly 3.9 inches (039), allowing deep insertion into bearing housings or casings while keeping the probe tip secure.
• The fitting option 03 supplies a 3/4-14 NPT plug, a 3/4-14 to 1/2-14 NPT reducer, and a multi‑size cable seal grip. The grip accommodates cables from 1/8 to 3/8 inches, providing conduit versatility.
• Mounting thread -02 specifies 3/4-14 NPT, the standard choice for industrial conduit systems. You must order this thread when the standoff adapter is not set to -00.
