Bently Nevada 330850-51-05 25 mm Proximitor Sensor
A five-metre-system DIN-mount Proximitor Sensor with the multiple-agency-approvals ordering option.
Product Overview
330850-51-05 is the Proximitor Sensor for a 3300 XL 25 mm proximity transducer system. Code 51 specifies a 5.0 m system length and DIN-rail mounting; code 05 specifies the multiple-approvals option.
The -05 approval suffix is the key distinction from 330850-51-00. The probe, extension cable, system length and installation approval requirements must all remain aligned.
Performance
- Conditions the matched 25 mm probe signal for compatible monitoring equipment.
- Supports non-contact measurement of shaft movement within the complete calibrated transducer system.
- Provides the DIN-mount, multiple-approvals execution required by the documented installation.

FAQ
What distinguishes 330850-51-05 from 330850-51-00?
The -05 suffix identifies multiple approvals, while -00 identifies no approvals; both use the 5.0 m DIN-mount execution.
Can 330850-51-05 be mixed with a 9 m extension-cable system?
No. The complete probe and extension-cable length must match the 5.0 m Proximitor calibration.
What approval evidence should accompany 330850-51-05?
Provide the sensor label and the project hazardous-area or agency requirement so the approval option can be checked.
What items should be ordered with 330850-51-05?
That depends on the installed loop; confirm the exact 25 mm probe, extension cable, mounting accessories and monitoring channel.
What commissioning checks are important for 330850-51-05?
Verify cable integrity, sensor mounting, probe gap, system output, monitor scaling and alarm behavior.
