Expert FAQ: 5/8-18 UNF & 5-Meter Probes
Thread & System Compatibility
Q: My equipment has an M14 threaded hole. Can I use this 5/8-18 UNF probe?
A> No. The 5/8-18 UNF thread is not compatible with M14 metric holes. You would need an adapter or must select the correct M14-threaded probe model.
Q: What does “for use with the five meter Proximitor Sensor only” mean?
A> The probe’s electrical length is calibrated for a 5-meter system. Using it with a 1-meter or 9-meter proximitor will result in incorrect gap voltage and scaling.
Specifications & Handling
Q: Why is the resistance higher (7.2Ω) than the 1-meter probe?
A> Resistance increases with conductor length. The 7.2Ω reading is normal and correct for the 5.0-meter integrated cable in this 330708-00-20-50 model.
Q: How should I handle the long 5-meter cable during installation?
A> Uncoil the cable fully before installation. Route it neatly, using clamps every 1-2 meters to prevent swinging or stress on the connector.
Ordering & Documentation
Q: Are the multiple approval certificates included?
A> Yes. The “05” option includes factory documentation for the applicable international certifications. These papers are shipped with the probe.
