Frequently Asked Questions (FAQ)

• Can I use this housing for a 5mm probe? This specific assembly (-28) is configured for a 3300 XL 8mm probe. For 5mm probes, a different probe option suffix is required.
• What is the purpose of the 0.5m cable length? The 0.5m cable is optimized for internal routing within the housing to reach the terminal strip without excess bulk.
• Does the "03" fitting option include grommets for all cable types? It includes three grommet sizes ranging from 1/8 inch to 3/8 inch, covering the vast majority of industrial coaxial cables.
• Is this assembly suitable for intrinsically safe loops? Yes, while the housing is explosion-proof, the probes can be ordered for intrinsically safe applications when used with appropriate barriers.
• Selection Guide: Why choose the 9.6-inch penetration (-096)? Choose the 21000-28-05-00-096-03-02 specifically for machines with thick walls or insulation where a standard 4-inch sleeve cannot reach the shaft.
