SR4MW: four circuits, 50.8 mm rotor, contacting seals
The SR4MW is a four-circuit SR Series end-of-shaft slip ring with a 50.8 mm (2 in) rotor (code M) and contacting rotary seals (code W) that make it weatherproof. The contacting seals limit its speed to 2 000 rpm. It carries strain gages, thermocouples and other sensors from rotor to stator through precious metal rings and brushes, in a stainless steel case.
The SR Series rotor flange is mounted to the end of the shaft, through an adapter if needed, with three #8-32 screws 120° apart. Sensor wires run along the shaft, or through a hollow shaft and a slot machined in it or in the adapter, to the color-coded rotor terminals. The bearings are lubricated for life.
For ten circuits, see the SR10MW. The part number guide explains the codes M, W and the connector options.

SR10MW: weatherproof ten-circuit end-of-shaft slip ring, 50.8 mm rotor, contacting seals
The SR10MW is an end-of-shaft slip ring with ten circuits rated at 500 mA. It mounts on the end of a rotating shaft and carries strain gages, thermocouples, accelerometers and low voltages from rotor to stator through precious metal rings and brushes, with a peak noise of 0.1 Ω. Contacting rotary seals (W) are added to its dust-sealed stainless steel case. Color-coded solder terminals sit on rotor and stator, and circular connectors are optional. Its rotor is 50.8 mm (2 in) in diameter; it runs up to 2 000 rpm, against 12 000 rpm without these seals, from −40 to 121 °C.
On installation, the rotor flange is mounted to the end of the shaft, through an adapter if needed, with three #8-32 screws 120° apart on a 43.2 mm (1.700 in) bolt circle. Sensor wires run along the shaft, or through a hollow shaft and a slot machined in it or in the adapter, to the rotor terminals. The bearings are lubricated for life; below −18 °C (0 °F), a low-temperature lubricant is specified. For a weatherproof stator connection, the optional circular connector is sealed at the rear of the plug with RTV silicone or a sealing backshell.
It is used, for example, for thermocouples on crankshaft bearings on an engine dynamometer or on an air conditioning compressor.

SR4MW/E60: weatherproof four-circuit end-of-shaft slip ring with 60 ppr encoder, 50.8 mm rotor
The SR4MW/E60 is an end-of-shaft slip ring with four 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. Contacting rotary seals make it weatherproof against water and dust and limit it to 2 000 rpm. With a 50.8 mm (2 in) rotor, it weighs 213 g and works 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, in harsh environmental conditions; with Michigan Scientific frequency-to-voltage encoder electronics, its pulses also give an analog speed signal for recorders that cannot read a pulse train.
