Frequently asked questions

What does the CN approval option mean?

The CN option indicates country specific approvals tailored for local regulatory requirements. For 330102-00-25-10-02-CN, this typically includes certifications needed for installation in China or regions with unique compliance standards.

What is the advantage of 2.5 inch case length?

The 2.5 inch case length offers a compact profile for machines with limited mounting depth. It provides enough rigid length for stable installation while minimizing overhang in tight spaces.

Can I use this probe with a 5 meter Proximitor?

No. 5-meter probes require a 5-meter Proximitor sensor. This 1.0 meter probe works with standard Proximitors. Always match total length to sensor type for proper calibration.

What is the maximum thread engagement depth?

Maximum thread engagement is 0.563 inch. With 2.5 inch case length and 0.0 unthreaded section, threads begin immediately. Use care to not exceed the engagement limit when setting the -9 Vdc gap.

Is this probe suitable for hazardous areas?

Yes, with proper installation using zener barriers or galvanic isolators per drawing 141092, it meets Class I, Zone 0 requirements. The CN approval ensures compliance with local hazardous area regulations.
