FAQ

• Q: What specific approvals does the "-05" suffix include? A> The "-05" suffix indicates multiple agency approvals including CSA (Canada/US), ATEX (Europe), and IECEx (international). Specific certificate numbers are available upon request.
• Q: Can I use this in Zone 1 hazardous areas? A> Yes, the multi-approval certification covers installation in hazardous locations. Verify the specific Ex rating (e.g., Ex ia IIC T4) against your area classification.
• Q: Is the "-05" version physically different from "-00"? A> The hardware is identical; the difference is in the certification documentation, labeling, and factory testing. The "-05" units undergo additional hazardous area validation.
• Q: What is the system length? A> 5.0 meters (16.4 feet) total system length including probe, extension cable, and proximitor. Do not attempt to extend or shorten the cable.

Installation Guide

1. Verify the hazardous area classification matches the proximitor's Ex rating before installation.
2. Mount on a grounded metallic panel in a non-hazardous or appropriately rated enclosure.
3. Use certified intrinsic safety barriers if installing in intrinsically safe loops.
4. Connect probe, extension cable, and power following the standard 3300 XL wiring practices.
5. Maintain separation between signal cables and power cables; use shielded cable with single-point ground.
6. Document the installation for hazardous area compliance audits.

Selection Tips

• Select 330850-50-05 for hazardous area applications requiring 5.0 m system length and panel mount.
• For non-hazardous applications, 330850-50-00 offers identical performance at lower cost.
• For DIN rail mounting with approvals, use 330850-51-05.
• Always verify local regulatory requirements; some regions may require specific approval marks not covered by "-05".
