Information
- Emerson PR9376-010-011 detects individual gear teeth without touching the rotating target. Its active Hall-effect circuit permits pulse acquisition at low speed while the protective cable hose supports exposed machine-side routing.
Selected lead: 5 m, armoured, open cable end
Supply and pulse rate: 10–30 VDC, maximum 12 kHz
For a 12 VDC supply and 100 kΩ load, the output high level exceeds 10 V and the low level is below 1 V. Rise and fall time is 1 µs. One signal cycle is produced per passing gear tooth, so the configured tooth count determines how pulse frequency is converted into shaft speed.
The reference target is a ferromagnetic spur wheel with involute teeth, using ST37 material. The indicated air gap is 1 mm for module 1 and 1.5 mm for module 2 or larger. Operation is limited to -25 to +100 °C, with IP67 sealing; target material and tooth geometry remain part of the measurement conditions.

Technical material for Emerson PR9376-010-011 covers Hall sensing, electrical levels and operating limits. PDF · 1 page.PR9376-010-011 Installation & Verification Guide
Apter Power installation and verification guide covering target selection, air-gap setup, power checks and pulse verification. PDF · 5 pages.
Application scope: Use a magnetic steel or soft-iron target with suitable geometry. Machinery applications include turbines, compressors, pumps and fans; the sensor alone does not provide shutdown logic.
Gear-tooth speed
Count pulses from the rotating ferromagnetic wheel and scale them by the actual teeth per revolution.Slow rotation detection
An active Hall circuit detects passing magnetic targets without relying on the speed-dependent amplitude of a passive pickup.Proximity indication
Use the high/low signal with a receiving input that accepts the sensor output levels and intended target movement.Armoured field routing
The protective hose supports routing between the measurement point and the external speed-monitor connection.
Use ferromagnetic target material and the specified tooth profile; stainless-steel targets are outside the stated target specification.
Match air gap to gear module and check runout and mechanical clearance over a complete revolution.
Confirm 10–30 VDC at the sensor connection and correct circuit polarity before applying power.
Compare input thresholds and loading with the conditional high/low output specification.
Support the armoured lead without pulling the open-end terminations or allowing contact with rotating parts.
Compare pulse count and indicated speed with the real target count before enabling alarms.

Technical notes
Signal relationship: Pulse frequency equals shaft revolutions per second multiplied by the number of target teeth. A speed setting that assumes one pulse per revolution will be incorrect when a multi-tooth wheel is used.
Installation boundary: The high/low output specification is conditional on 12 VDC and 100 kΩ loading. Check the actual receiving-input thresholds instead of treating the full 10–30 VDC supply range as a single output-voltage rating.
Technical basis: Emerson PR9376 Hall Effect Speed/Proximity Sensor Specifications Sheet, August 2024. The PR9376 ratings apply to the selected /010-011 armoured 5 m version under the stated target, gap, supply and load conditions.
FAQ View All FAQ
-
How many pulses should PR9376-010-011 generate from a 60-tooth wheel?It generates one cycle for each passing tooth, giving 60 cycles per revolution. Shaft rpm is 60 times pulse frequency divided by the number of teeth.
-
Does PR9376-010-011 need an external supply when measuring slow rotation?Yes. It is an active Hall-effect sensor requiring 10–30 VDC, with a maximum supply current of 25 mA. It is not a self-powered magnetic pickup.
-
Why is a stainless-steel target unsuitable for the stated PR9376-010-011 performance?The specified target is magnetic soft iron or non-stainless steel. The reference spur-wheel material is ST37; do not assume equivalent response from a nonmagnetic stainless-steel target.
-
What changes in the permitted PR9376-010-011 gap between module-1 and module-2 gears?The indicated gap is 1 mm for module 1 and 1.5 mm for module 2 or larger. Tooth geometry and target runout must also be considered.
-
At what load are the PR9376-010-011 high and low levels defined?The levels are defined at 12 VDC with a 100 kΩ load: high above 10 V and low below 1 V. Verify the receiving input against those conditions.
-
Can PR9376-010-011 count more than 12,000 teeth per second?No. Its maximum operating pulse frequency is 12 kHz. This limit is a tooth-passage frequency, so maximum shaft speed depends on the number of teeth.
-
How is the selected cable of PR9376-010-011 terminated?The 5 m armoured cable has an open end for field termination. Do not treat it as a pre-terminated connector version.
-
Which environmental limits apply to PR9376-010-011 at the machine?The operating range is -25 to +100 °C and the sealing rating is IP67. Storage is -40 to +100 °C; storage limits do not widen the operating range.
