Description

Option 02 (20 mm unthreaded length) and Option 06 (60 mm overall case length) specify this 3300 XL 8 mm metric proximity probe configuration — 330103-02-06-10-02-00, a non-contacting eddy-current proximity probe featuring a metric M10 x 1 thread without mechanical armor. This configuration includes a 1.0 meter (3.3 feet) standard coaxial cable with a miniature coaxial ClickLoc connector and is supplied without agency approvals (Option 00). The M10 x 1 threaded body provides direct compatibility with metric machinery mountings, allowing physical proximity measurement of target shafts.

This specific metric variant contrasts with standard fractional configurations (such as the 3/8-24 UNF threaded 330101 series) or armored configurations (such as the 330104 series). It operates within the 3300 XL Transducer System, pairing with a 3300 XL Proximitor sensor and a standard extension cable to achieve a total system length of either 5.0 or 9.0 meters. The unarmored 75 ohm triaxial FEP-insulated probe cable maintains a minimum bend radius of 25.4 mm (1.0 inch) for routing in tight machine enclosures.

Features

• Option 02 specifies a 20 mm unthreaded length, leaving 40 mm of threaded case length for mounting engagement.
• Option 06 establishes a 60 mm overall case length with an unarmored construction.
• Option 10 provides a 1.0 meter (3.3 feet) total probe lead length.
• Option 02 connector type features a miniature ClickLoc coaxial connector without a connector protector on a standard cable.
• Option 00 indicates that agency approvals are not required for this configuration.
• M10 x 1 metric thread conforms to standard metric mechanical specifications.
• Polyphenylene sulfide (PPS) probe tip material withstands typical industrial environments.
• 75 ohm triaxial fluoroethylene propylene (FEP) insulated cable supports low-noise signal transmission.

Applications

This metric probe is used for industrial machinery protection and condition monitoring. Typical applications include:

• Radial vibration monitoring on high-speed rotating shafts
• Axial thrust position measurements on steam and gas turbines
• Eccentricity measurements on generator shafts
• Keyphasor reference and speed measurements on compressors and pumps
• Vibration monitoring in petrochemical, power generation, and gas processing plants

Installation Guidelines

• Mounting Torque: Do not exceed the maximum rated torque of 22.6 N-m (200 in-lbf) for standard forward-mounted M10 x 1 probes during installation. The recommended mounting torque is 7.5 N-m (66 in-lbf).
• Thread Engagement: Maintain thread engagement within the maximum limit of 15 mm for M10 x 1 threads to avoid binding.
• Cable Routing: Ensure the 75 ohm triaxial coaxial cable maintains a bend radius of at least 25.4 mm (1.0 inch) to prevent physical or electrical degradation of the conductor.
• Connector Protection: Use a connector protector or self-fusing silicone tape (not inside the machine casing) to prevent moisture or oil ingress at the ClickLoc connection point with the extension cable.
• Gap Adjustment: Adjust the mechanical gap using a feeler gauge or by measuring the DC voltage output at the Proximitor sensor (typically set to a nominal -10 Vdc corresponding to a 1.27 mm mechanical gap on AISI 4140 steel).
