Product Overview
The Bently Nevada 330174-00-04-20-02-CN is a 3300 5mm proximity probe with an M8 x 1 thread and armored cable. Made in the U.S.A., this industrial automation module measures the gap between the probe tip and a conductive target in a proximity transducer system. A polyphenylene sulfide (PPS) tip and an AISI 304 stainless steel case protect the sensing assembly, while the miniature coaxial ClickLoc connector creates a secure cable connection. The probe ships with a 2.0 metre (6.6 feet) total cable length.
When cable wear, high temperature, or line-frequency magnetic fields threaten measurement integrity, the Bently Nevada 330174-00-04-20-02-CN stands up to the challenge. The armored construction protects the 75 Ω triaxial cable from abrasion, and the stainless steel case resists corrosion. The probe operates from -35°C to +177°C, which suits demanding industrial environments. Minimum cable bend radius is 25.4 mm, so technicians can install the cable without creating sharp bends that might degrade signal quality.
The 60 Hz magnetic field data for a 5 meter system shows low output voltage contribution from the probe across 10, 50, and 90 mil gaps. This makes the Bently Nevada 330174-00-04-20-02-CN a stable choice when magnetic interference is present.

Applications and Use Cases
Because the Bently Nevada 330174-00-04-20-02-CN is a 5mm proximity probe with a 2.0 metre cable, it fits systems that monitor the relative position of a metallic target. The M8 x 1 thread allows installation into standard threaded mounting holes. The PPS tip and stainless steel case give this probe a rugged sensing package. Use this probe whenever a robust proximity sensor must be mounted close to a steel target for gap measurement.
Installation and Setup Guidance
Install the Bently Nevada 330174-00-04-20-02-CN into an M8 x 1 threaded hole with the probe face aimed at the target. Tighten the probe case to 5.1 N·m recommended torque and never exceed 7.3 N·m. Maximum thread engagement is 12 mm. Use the miniature coaxial ClickLoc connector to join the probe lead to an extension cable; connector-to-connector torque should not exceed 0.565 N·m (0.42 ft·lbf). Maintain a minimum cable bend radius of 25.4 mm.
Maintenance and Reliability
Keep the probe tip clean and inspect the armored cable for damage after each maintenance window. The probe temperature range is -35°C to +177°C. Avoid prolonged exposure below -34°C because the pressure seal may fail prematurely. Operating at a supply voltage more positive than -23.5 Vdc can reduce linear range. Checking output sensitivity, which is less than 2 mV change per volt change, helps confirm correct system operation.
Selection Guide and Purchasing Advice
Confirm that the 330174-00-04-20-02-CN configuration matches your application before ordering. The 00 unthreaded length option means 0 mm, the 04 overall case length option means 40 mm, the 2.0 total length option means 2.0 metres (6.6 feet), the 02 connector option means miniature coaxial ClickLoc connector with standard cable, and the CN agency approval option is country-specific.
