Provides a nominal 4 V/mm sensitivity with a stated tolerance of no more than ±1.5%.
Product Overview
PR6424/011-110 is an Emerson 16 mm eddy-current sensor configuration for non-contact vibration and position measurement on rotating machinery.
The complete ordering code specifies an M18 × 1.5 sleeve thread, armored cable, 50 mm case dimension, no adapter plug, 5.0 m total cable and a LEMO cable end.
Performance
Supports a static measuring span of ±2.0 mm and dynamic movement from 0 to 1000 µm.
Uses a 2.7 mm center gap with the referenced 42CrMo4 ferromagnetic-steel target.
Accommodates large-shaft applications with a documented minimum shaft diameter of 80 mm.

System Integration
- Verify M18 × 1.5 mounting, available case depth and cable bend path before installing PR6424/011-110.
- Pair the sensor only with the documented converter and monitor channel for the PR6424 calibration system.
- Set the operating gap electrically against the approved target material and retain the final gap voltage.
- Protect the 5 m armored lead and LEMO termination from strain, contamination and high-energy cable routes.
Applications
- Relative shaft vibration and position measurement on large rotating-machine shafts.
- Machinery protection channels requiring the PR6424 16 mm measurement geometry.
- Replacement of the exact armored, 5 m, no-adapter configuration after mechanical and converter checks.
FAQ
What distinguishes PR6424/011-110 from nearby PR6424 codes?
The exact code fixes the M18 × 1.5 thread, armor, 50 mm case dimension, absence of an adapter plug, 5 m cable and LEMO end.
Can PR6424/011-110 be used on a shaft smaller than 80 mm?
The manufacturer data specifies an 80 mm minimum shaft diameter for the stated performance; a smaller target requires engineering review.
What must match when replacing PR6424/011-110?
Confirm mechanical code, cable length and end, target material, converter family, monitor scaling and the installed gap procedure.
How should PR6424/011-110 be routed near the machine?
Respect the armored-cable bend requirement, secure the lead without crushing it and keep the signal route separated from high-energy switching conductors.
Which commissioning values should be saved for PR6424/011-110?
Record gap voltage, slow-roll runout, channel scale, alarm settings, converter identity and measured loop behavior.
