21000-34-05-15-030-03-02 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 0.5 m (20 in) probe cable permanently attached to the sensor. The cable length optimizes connections in compact machinery layouts without excess signal loss.
• A 1.5 inch standoff adapter positions the probe correctly relative to the target. This adapter simplifies installation and maintains precise air gap settings.
• Probe penetration measures exactly 3.0 inches (030), 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.
