Detects a ferrous rotating target without mechanical contact.
Key Information
PR9376/010-011 is a Hall-effect speed and proximity sensor for turbines, compressors, pumps and fans. It produces one output cycle for each passing revolution marker or gear tooth.
The complete PR9376/010-011 code identifies the armored-cable execution with a 5 m cable and open cable end. These construction details should not be substituted from another PR9376 suffix.
Functions
Provides a fast square-wave signal for speed, key or proximity monitoring channels.
Operates with spur-wheel involute gearing and magnetic soft iron or non-stainless steel targets.
Uses armored cable construction to protect the installed lead in mechanically demanding routes.

Installation
- Verify target material, tooth geometry, air gap and maximum running frequency before mounting the sensor.
- Route the 5 m armored lead without sharp bends, crushing or strain at the sensor body and termination.
- Set the gap statically, then prove pulse amplitude and frequency through the complete monitor channel during controlled rotation.
- Document wire identification at the open cable end before disconnecting an installed sensor.
Lifecycle
- Protect the sensing face and cable termination during storage and transport.
- Retain target geometry, final gap, polarity and observed pulse level in the commissioning record.
- Inspect armor and cable entry periodically where vibration or repeated maintenance can fatigue the lead.

FAQ
What must be matched before replacing PR9376/010-011?
Confirm the complete suffix, 5 m armored lead, open-end termination, supply voltage, target material and installed air gap.
Can PR9376/010-011 read a stainless-steel target?
The specified target is magnetic soft iron or non-stainless steel. A stainless target should not be accepted without an application-specific validation.
How is the correct air gap for PR9376/010-011 established?
Use the target module and the manufacturer limits, then verify the resulting pulse level through the installed monitoring input.
What incoming checks are useful for PR9376/010-011?
Inspect the sensing face, armor, full cable length and open conductors, then perform safe continuity and supply checks before installation.
Why should the existing pulse waveform be recorded before changing PR9376/010-011?
A baseline waveform helps separate target runout, gap and wiring effects from a genuine sensor problem after replacement.
