Brand: Michigan Scientific
SKU: B4-3.2

Four-circuit tubular slip ring, 2 in bore

The B4-2 is a tubular slip ring with four circuits rated at 1 A. It mounts on the shaft, which passes through its 50.8 mm (2 in) bore, and carries strain gages, thermocouples, accelerometers and low voltages from rotor to stator. Its rings are solid silver alloy and its brushes silver-graphite. The rotor carries color-coded solder terminals with redundant back-up terminals, and the stator a connector supplied with its mating connector. It is 26.9 mm wide and runs up to 7 000 rpm, from −40 to 121 °C.

On installation, the rotor is secured to the shaft with six #8-32 set screws, square and concentric to the axis of rotation; a bushing adapts it to shafts smaller than 50.8 mm. Sensor wires run along the outside of the shaft and through slots in the rotor to the solder terminals, in stranded wire of 24 AWG at most, then are secured to the shaft and coated with RTV silicone. The stator is held by a flexible restraint, such as a small cable, a spring or a wire tie, rather than by its cable. The silver contacts are wear parts: they are inspected periodically and last about 100 million revolutions under ideal conditions.

It is typically used on automotive drive shafts, for example to measure prop shaft torque at the transmission output or half shaft torque.
