Ten-circuit end-of-shaft slip ring with 60 ppr encoder, 50.8 mm rotor

The SR10M/E60 is an end-of-shaft slip ring with ten circuits rated at 500 mA and a 60 pulse-per-revolution encoder. It mounts on the end of a rotating shaft and carries strain gages, thermocouples, accelerometers and low voltages from rotor to stator, while the encoder measures rotational speed. Its rings and brushes are precious metal, and its terminals color-coded. The housing is sealed against dust, and a manual brush lifter lifts the brushes off the rings when no signal is needed. With a 50.8 mm (2 in) rotor, it is 57.9 mm long, weighs 213 g and runs up to 6 000 rpm, from −40 to 100 °C.

On installation, the rotor flange is screwed to the end of the shaft with three 8-32 screws on a 43.18 mm (1.700 in) circle. The encoder is powered with 5 to 15 V DC. The bearings are lubricated for life, and a low-temperature lubricant is specified below −18 °C. A rubber boot or a metal cap adds a cable or connector to the stator terminals, and a circular connector can replace the rotor terminals.

It is used where a slip ring and a speed encoder are both needed on the end of a shaft; with Michigan Scientific frequency-to-voltage encoder electronics, its pulses also give an analog speed signal for recorders that cannot read a pulse train.
