PR642X FAMILY
Selecting the Right Sensor Size and Range
The PR642x family covers different sensor sizes and measurement ranges. PR6426 is the large-shaft option within the family and is intended for large position measurements.

BUYER QUESTIONS
PR6426-010-140 FAQ
Configuration, replacement and application questions that matter when selecting this sensor.
Can PR6426-010-140 be selected when the existing machine has a large shaft?
The PR6426 is specifically designed for large position measurements on large shafts, with a minimum shaft diameter of 200 mm specified for its dynamic performance. The complete installed geometry and measurement requirement should still be checked before replacement.
Why does PR6426-010-140 require attention to the companion converter?
PR6426 sensors operate as part of an eddy-current measurement chain. Emerson specifies different converter measuring ranges for PR6426, so the sensor and converter configuration should be matched to the required measuring range.
Does PR6426-010-140's 10 m cable matter when replacing an installed sensor?
Yes. The exact configuration is associated with a 10 m total cable length and LEMO cable end. Cable length and connector arrangement should therefore be checked against the existing installation rather than treating PR6426 variants as interchangeable.
When is PR6426-010-140 more relevant than another PR642x sensor?
PR6426 is the 32 mm sensor type intended for large-shaft position measurements. The other PR642x sensor types use different sensor dimensions and standard converter ranges, so selection should follow shaft size and required measurement range.
What should a buyer verify before ordering PR6426-010-140 as a replacement?
Verify the complete part number, 32 mm sensor size, no-thread configuration, armored cable arrangement, mounting configuration, 10 m total cable length, LEMO cable end, shaft diameter, required measurement range and the installed signal converter. This avoids replacing a sensor with a visually similar but differently configured PR6426 variant.
