HT-400 Brushless Single-Turn Resolver Transducer
The resolver is a highly accurate and highly dependable device for absolute position shaft encoding.
Resolvers have a reliable track record of applications in aerospace, military and industry, where they have been used for decades for position sensing.
Some of the common applications are radar antenna position sensing, missile guidance systems, NC machine position feedback, automotive stamping presses, 2-piece-can manufacturing presses and packaging machines.
Unlike incremental encoders, the resolver is designed to operate reliably under extremely hostile environments such as continuous mechanical shock, vibration. extreme temperature and humidity changes, oil mist, coolants and solvents.
The resolver is a passive transducer. It is a brushless rotary transformer with one rotor and two stator windings. The stator windings are electrically 90º out-of-phase with each other.
As the shaft rotates, the relative position of the rotor and the stator windings change. Either the rotor or two stator windings together can be used as the primary of the rotary transformer and the secondary will then produce analogue voltage corresponding to the shaft position.
Redesigned for complete mechanical and electrical compatibility with AVG/Autotech SAC-RL100’s and Gemco Series I transducers, the HT-400 is an IP64 rated heavy-duty 4-inch diameter resolver based transducers.
Available with a 1-inch conduit fitting or connector, all size 400 transducers feature a unique termination block that allows you to switch between conduit and connector terminations in the field.
Not only does this allow you to reduce the number of spares you need to stock, but this system also allows you to make connector and conduit repairs in the field, sometimes without removing the transducer from the machine.
As well as termination flexibility, the HT-400 transducers allow you to design new systems around an industry standard package, quickly upgrade or repair existing machines.
