These specifications are for a 3300 5 mm system including a Proximitor sensor, extension cable, and probe, with a -24 Vdc supply and 10 kΩ load, using an AISI 4140 steel target.
Applications
The 146054-040-10-02-05 is ideal for monitoring shaft vibration and axial position in rotating machinery such as turbines, compressors, and pumps. Its ceramic tip resists wear and provides stable readings in harsh environments. Use it in conjunction with a 3300 XL Proximitor for accurate, repeatable measurements.
Installation & Setup
Mount the probe with the 3/8-24 UNF thread into a properly tapped hole. Ensure the cable is routed without sharp bends. The ClickLoc connector simplifies extension cable attachment—push until it clicks. Calibrate the system with an AISI 4140 steel target to achieve the specified ISF and linear range.
Maintenance & Reliability
Inspect the probe tip periodically for contamination or damage. The ceramic cap is robust, but debris can affect accuracy. Verify cable integrity and connector tightness. With proper care, this probe provides long-term, drift-free performance, reducing downtime and maintenance costs.
Selection Guide
When ordering, verify the part number breakdown: 146054-AA-BB-CC-DD. AA=-040 (case length), BB=-10 (cable length), CC=02 (connector type), DD=-05 (approvals). For assistance, contact PLC Source PRO to ensure you select the correct configuration.
