    HTT- 425 Brushless Multi-turn Resolver Transducers

    These multi-turn resolver transducers are widely used for mounting to either servo motor end bells or foot mounted to accept a large pulley or drum. The IP67 rating is essential when the resolver transducer is mounted in an outdoor environment.

    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.
