Emerson EPRO PR9376/010-011 Hall Effect Speed Proximity Sensor 25°C With Armored Cable 5m

Emerson EPRO PR9376/010-011 Hall Effect Speed-Proximity Sensor 25°C with Armored Cable 5m

Product Overview
The Emerson PR9376/010-011 is a rugged, inductive proximity speed/phase reference sensor designed for critical turbo-machinery monitoring. Part of the legacy EPRO portfolio now integrated into Emerson’s Machinery Health® family, it delivers reliable, non-contact detection of ferromagnetic targets on rotating shafts, making it ideal for speed, key-phasor and synchronous-phase applications up to 20 kHz.

Key Features & Benefits
