Frequently asked questions

Why choose the 7.9 inch case length?

The extended 7.9 inch case length allows this probe to reach deeper mounting locations. It is ideal for machines with thick casings or when you need to position the probe further from the mounting surface.

What is the total length of this probe?

330102-00-79-05-02-05 has a 0.5 meter (1.6 feet) total length including cable. The case length is 7.9 inches, with 0.0 inches unthreaded section before the threads start.

What approvals does the 05 option include?

The 05 agency approval option includes CSA, ATEX, and IECEx certifications. This makes 330102-00-79-05-02-05 suitable for hazardous area installations requiring multiple international approvals.

Can I use this probe with a 5 meter Proximitor?

No. 5-meter probes require a 5-meter Proximitor sensor. This 0.5 meter probe works with standard Proximitors. Always match total length to sensor type.

What is the maximum thread engagement depth?

Maximum thread engagement is 0.563 inch. With 7.9 inch case length and 0.0 unthreaded section, threads begin immediately at the probe tip. Ensure you do not exceed the engagement limit.
