Quick Detail

Description

The 330101-00-20-20-02-05 3300 XL 8 mm Proximity Probe is a high-performance eddy current sensor engineered for precision automation and rotating machinery monitoring. This 3300 XL 8 mm Proximity Probe converts the gap between its probe tip and a conductive target into a stable voltage output, providing accurate measurements of both static shaft position and dynamic vibration. With a 2 mm (80 mils) linear range, it is optimized for fluid-film bearing machines, compressors, turbines, and pumps where automation systems demand high reliability and precise feedback.

The 330101-00-20-20-02-05 probe features a 3/8-24 UNF threaded stainless steel case, a 2.0 meter standard cable, and a Miniature coaxial ClickLoc connector that ensures secure, vibration-resistant electrical connections. Its robust design operates over a wide temperature range of -52°C to +177°C, with 50 Ω output resistance, less than 2 mV/V supply sensitivity, and 69.9 pF/m typical extension cable capacitance for long-distance signal stability. Certified with CSA, ATEX, and IECEx approvals, the 3300 XL 8 mm Proximity Probe is ideal for hazardous-area automation and industrial monitoring applications, delivering consistent and reliable performance under extreme operating conditions.
