System Compatibility Notes

• Specifications apply to 3300 5 mm systems including Proximitor Sensor, extension cable, and probe.
• Performance characteristics apply only to systems with 3300 XL components.
• Calibration uses AISI 4140 steel target between +18°C and +27°C with -24 Vdc supply and 10 kΩ load.
• The 2.0 meter probe 146054-08-20-01-00 works with matching Proximitor Sensor configurations.
• System accuracy and interchangeability specifications require AISI 4140 steel target.

Installation Guidelines

• Mount the probe using the 3/8-24 UNF thread with maximum engagement of 0.563 inches.
• Connect using the miniature coaxial ClickLoc connector with protector for tool-free, secure installation.
• The connector protector adds mechanical protection to the connection point.
• Ensure the target material matches AISI 4140 steel for specified accuracy.
• This configuration is for non-hazardous areas only (no agency approvals).
• Contact Bently Nevada for high-pressure applications exceeding 34 Bar.
