Description
31000-28-05-00-037-03-02 Proximity Probe Housing Assemblies are designed for external mounting of proximity probes in industrial automation and machinery monitoring systems. 31000-28-05-00-037-03-02 is supplied with a 3300 XL 8 mm proximity probe with multiple approvals and a 0.5 m probe cable, supporting vibration and Keyphasor measurements on rotating equipment.
The 31000-28-05-00-037-03-02 housing allows a probe penetration depth of 3.7 in (94 mm) without a standoff adapter and uses a 3/4-14 NPT mounting thread for installation through machine casings. The assembly includes two plugs, a 3/4-14 NPT fitting, a 3/4-14 to 1/2-14 NPT stainless steel reducer, and a cable seal grip with grommets for cable diameters from 1/8 to 3/8 in. Recommended retaining nut torque for 31000-28-05-00-037-03-02 is 29.4 N·m.
The 31000-28-05-00-037-03-02 housing body is manufactured from glass-reinforced PPS with conductive fibers, while the sleeve and external hardware use AISI 304 and AISI 303 stainless steel. With a CSA Type 4X rating and certified impact resistance at temperatures from -39°C to 115°C, 31000-28-05-00-037-03-02 supports probe access, gap adjustment, and replacement without machine disassembly in automated plant environments.
Applications
Radial Vibration Measurement Through Machine Casing
31000-28-05-00-037-03-02 is used to mount a 3300 XL 8 mm proximity probe through the machine case for radial vibration measurement. With a probe penetration of 3.7 in and a 3/4-14 NPT mounting thread, 31000-28-05-00-037-03-02 allows accurate probe positioning on bearing housings while keeping the probe and extension cable accessible from outside the machine.
Keyphasor Signal Pickup for Speed Reference
31000-28-05-00-037-03-02 supports Keyphasor measurements by providing a rigid external housing for the proximity probe. The 0.5 m probe cable and integrated conduit fittings enable direct routing to speed monitoring modules used in automated control systems.
Probe Replacement Without Machine Disassembly
31000-28-05-00-037-03-02 allows technicians to adjust probe gap or replace the probe without opening the machine casing. This reduces downtime during maintenance of turbines, compressors, and pumps connected to automation systems.
Installation in Hazardous and Outdoor Areas
With a CSA Type 4X rating and certified impact resistance at -39°C and 115°C, 31000-28-05-00-037-03-02 is used in outdoor or hazardous locations where proximity probes must be protected from water ingress and mechanical impact.

Competitive Advantage
Defined Mechanical Protection for the Probe
The glass-reinforced PPS housing and stainless steel sleeve allow 31000-28-05-00-037-03-02 to shield the proximity probe from mechanical contact and corrosive process fluids while maintaining a fixed probe penetration depth of 94 mm.
Complete Conduit and Cable Sealing Package
31000-28-05-00-037-03-02 includes plugs, reducers, and a cable seal grip with grommets for cable sizes from 1/8 to 3/8 in, reducing the need for additional field-supplied fittings during automation project installation.
Certified Impact and Enclosure Ratings
The CSA Type 4X enclosure and BASEEFA-certified 4 Joule impact rating allow 31000-28-05-00-037-03-02 to remain installed in areas subject to physical contact and temperature extremes without added protective covers.
Controlled Installation Torque
A recommended retaining nut torque of 29.4 N·m allows 31000-28-05-00-037-03-02 to be mounted consistently across multiple machines, supporting repeatable installation practices in large automation deployments.
