Description
The 21000-16-05-20-065-04-02 Proximity Probe Housing Assembly is part of a rugged all-metal housing family designed for external mounting of 3300 XL 8 mm probe systems. It integrates a probe sleeve, dome cover, and sealed structure to ensure reliable operation in demanding industrial environments. The assembly is engineered to support stable positioning of the probe while maintaining mechanical protection and environmental sealing for continuous monitoring applications.

This housing supports a 0.5 m (20 in) probe cable length, with a 2.0 in standoff adapter option (C dimension) and a 6.5 in probe penetration (D dimension). It is equipped with 1/2-14 BSP fittings and two 3/4-14 NPT explosion-proof mounting threads, making it suitable for hazardous area installations. The aluminum body combined with a 304 stainless steel sleeve ensures both structural strength and corrosion resistance in long-term industrial use.

The design includes essential components such as O-rings, thread seals, optional conduit fittings, and a reverse mount probe configuration. These elements work together to maintain sealing integrity and ensure consistent measurement performance even in vibration-heavy environments. The CSA-approved explosion-proof rating further enhances its suitability for oil & gas, petrochemical, and heavy machinery applications.

Compared with similar housing solutions such as the 24701 stainless steel probe housing assembly, the 21000-16-05-20-065-04-02 offers a lightweight aluminum structure while still maintaining explosion-proof protection. This makes the 21000-16-05-20-065-04-02 more practical in installations where weight reduction is important without compromising durability and safety.
