Description
The Model 21000-28-05-00-40-03-02 is a precision-engineered aluminum Proximity Probe Housing Assemblies
assembly designed for external mounting of proximity probes on industrial machinery. This 21000 series housing features a durable all-metal aluminum construction with a dome cover that screws securely into the housing body, providing robust protection for the installed proximity probe. 

The configuration of the 21000-28-05-00-40-03-02 includes a 0.5 meter (20 inch) probe cable length with a probe penetration of 4.0 inches, providing the necessary reach for installation through machine casings. This model features no standoff adapter and utilizes a 3/4-14 NPT mounting thread for secure installation. 

Certification and compliance are key features of the 21000-28-05-00-40-03-02. This housing assembly is available in a Canadian Standards Association (CSA) approved version rated explosion proof for hazardous areas. The 21000-28-05-00-40-03-02 is certified as CSA Type 4 enclosure, providing protection against falling dirt, windblown dust, rain, splashing water, and hose-directed water. 

Installation flexibility is enhanced by the design of the 21000-28-05-00-40-03-02. The housing incorporates O-rings and a thread seal to prevent contamination ingress. For sleeve lengths longer than 304 mm (12 inches), additional sleeve support is required to reduce vibration associated with unsupported long sleeves. While this configuration has a 4.0 inch penetration, a probe support/oil seal (P/N 37948-01) is available for applications requiring support through inner bearing housings.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the primary purpose and key benefit of the 21000-28-05-00-40-03-02 probe housing assembly?
The 21000-28-05-00-40-03-02 is an aluminum proximity probe housing assembly designed for external mounting of 3300 XL 8 mm proximity probes on industrial machinery. Its primary benefit is providing external access to the proximity probe and its extension cable, permitting gap adjustment or probe replacement without requiring disassembly of the machine, significantly reducing maintenance downtime and complexity.
What certifications and standards does the 21000-28-05-00-40-03-02 comply with?
The 21000-28-05-00-40-03-02 is available in a CSA approved version rated explosion proof for hazardous areas, and is certified as CSA Type 4 enclosure providing protection against falling dirt, windblown dust, rain, splashing water, and hose-directed water. The housing is fully compliant with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probe housings. CSA and BASEEFA approved proximity probes can also be used with this housing for intrinsically safe applications.
What fittings and components are included with the 21000-28-05-00-40-03-02 assembly?
The 21000-28-05-00-40-03-02 comes complete with one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and a cable seal grip with grommets accommodating multiple cable sizes: 1/8 to 3/16 inch, 1/4 to 5/16 inch, and 5/16 to 3/8 inch. The assembly includes a dome cover that screws into the housing body, threaded ports for conduit connections, a probe sleeve of 4.0 inch penetration, O-rings, and a thread seal.
What are the differences between the 21000-28-05-00-40-03-02 and the alternative 24701 housing?
The 21000-28-05-00-40-03-02 is constructed of aluminum, offering lightweight corrosion resistance suitable for most industrial applications. The alternative 24701 housing is constructed of stainless steel, providing enhanced corrosion resistance for more aggressive environments. Both housings offer the same CSA Type 4 certification, API 670 compliance, and external probe access benefits. For sleeve lengths longer than 304 mm (12 inches), both require additional sleeve support such as the probe support/oil seal P/N 37948-01 to reduce vibration.
