    H25 Allen-Bradley 846 Resolver Replacement

    AMCI's stainless steel H25 series resolver transducer is a size 25 package with a flange mount and end connector design, simplifying new installations or transducer replacements. This IP67 rated transducer is made from 304 stainless steel and withstands operating temperatures up to 150°C (302°F).

    The corrosion resistant construction of AMCI's stainless steel H25 resolver transducer, along with its extreme temperature rating allow it to be used in environments where most sensors will not survive. High performance applications like those found in paper factories, steel mills, and mining operations are the inspiration for this extreme-duty rotary sensor. Plus the unit's stainless steel construction make it perfect for food grade installations.

    The rotor of the stainless steel H25 brushless resolver is built on the input shaft, minimizing component count & maximizing reliability. In other words, the rotor & stator assembly are integrated into the unit's design eliminating the use of separate internal resolvers and couplings to the external shaft. The net result is a "bullet-proof" resolver transducer with unmatched durability.

    AMCI's stainless steel H25 is available with 3/8", 10mm(-10 option), or 1/4"(-03 option) shaft, mil-spec connector, and flange mount.

    AMCI offers a complete line of resolver interface solutions, enabling you to easily configure a resolver-based position feedback system in your favorite PLC, PAC, or network.

    Heavy-Duty Reliability

    The resolver transducer was originally developed to withstand the punishment of military applications, and has since benefited from more than 50 years of continuous use and development. Product packaging plants and stamping press lines are perfect examples of where you might find resolver based systems at work today.

    Builders and system integrators alike agree that the resolver transducer is unsurpassed in its ability to reliably supply rotary position data in the harshest industrial environments.

    The AMCI resolver product line is offered in aluminum or stainless steel construction, and boasts up to an IP67 rating. Solid shaft and hub shaft versions are available, and both types incorporate an oversized double row bearing that supports shaft loads up to 100 lbs. radial / 50 lbs. axial.
