FAQ

• Can I use this probe with a Proximitor from another series? Yes, but we recommend matching with 3300 XL Proximity Probes system components for optimal linearity.
• What is the difference between suffix 05 and 00 for approvals? Suffix 05 provides CSA, ATEX, IECEx; suffix 00 has no approvals.
• Does this probe include the connector protector? Yes, suffix 01 includes the miniature coaxial ClickLoc™ with protector.
• Can I extend the cable beyond 0.5 m? Yes, use triaxial extension cable up to 305 m total; follow frequency response graphs.
• Is this probe reverse‑wired? No, standard configuration: center conductor to outer conductor resistance 7.45 Ω.
