Ordering information

H25 Brushless Single-turn Resolver Transducer

FEATURES:

IP67 rated; superior durability in harsh environments
Ideal for high-shock applications
Direct replacement for AB Bulletin 846
Variety of mounting styles
100% compatible with AMCI's complete line of resolver interface products

DESCRIPTION

The H25 Series resolver transducer package offers a variety of mounting and connector styles. This IP67 rated package is the size of a 2.5" dia. optical encoder yet provides the ruggedness and durability of a resolver. No optical encoder can match its specifications. Available with 3/8", 10mm(-10 option), or
1/4"(-03 option) shaft, mil-spec connector, and flange or servo mount.

Additionally, the H25 Series resolver transducer can be ordered with a heavy duty 5/8" (-05 option) shaft and flange mount for applications involving high side loads.
