Option 39 (3.9 in unthreaded length) and Option 71 (7.1 in case length) specify this unarmored 3/8-24 UNF threaded proximity probe configuration — 330908-39-71-05-01-00. This 3300 NSv proximity probe is used for applications with small target areas or restricted mounting spaces where standard 5 mm or 8 mm proximity systems cannot operate effectively. It pairs with a 3300 XL NSv Proximitor Sensor and a 330930 extension cable to form a complete eddy-current measurement system.
This specific configuration lacks stainless steel armor and features a 0.5-meter (20 inches) total length (Option 05). It is equipped with a miniature coaxial ClickLoc connector with an integrated fluorosilicone connector protector (Option 01). No hazardous area agency approvals are required for this model (Option 00), making it suitable for standard safe-area installations.
