SRA-73574 / SRA-73587


The SRA-73574 / SRA-73587 slip ring remains in production at Moog, supporting customers with power and data transfer applications.

A slip ring capsule can be used in any electromechanical system that requires unrestrained, intermittent, or continuous rotation while transferring power and / or data.

The SRA-73574 / SRA-73587 compact slip ring capsule provides an economical, readily available solution when a compact, high circuit count configuration is required. Our standard units, offer 36, 2 amp, 4, 10 amp and 24, 2 amp signal rings, respectively. These units can be modified to provide various combinations of power, signal and coax circuits. Similar in design to our very popular AC6023, this design features gold-on-gold contact technology for ultimate performance in many challenging applications.

Typical applications include pan / tilt camera mounts, rotary index tables, rate tables, lighting and robotics.
