Short S4: four-circuit compact end-of-shaft slip ring
The Short S4 is the four-circuit model of the Short S-Series. It mounts on a shaft end and carries strain gages, thermocouples, accelerometers and low voltages from rotor to stator. Its four circuits are rated at 500 mA through precious metal rings and brushes, with a peak resistance variation of 0.1 Ω, and the stainless steel and aluminum case is sealed against dust. The rotor, 41.28 mm (1.625 in) in diameter, carries two redundant sets of color-coded solder terminals. The Short S4/X is 22.15 mm long, weighs 56 g and runs up to 12 000 rpm, from −1 to 138 °C. A colder environment is specified when ordering.
It is ordered as Short S4/X, with a miniature connector on the stator and one 3 m (10 ft) cable; Short S4, with end terminals on the stator; Short S4/T, with stator terminals; Short S4/TG, with stator terminals and no restraint bracket; or Short S4/T/LHV, with stator terminals and a lubrication hole. The part number guide explains the suffixes.
The rotor is fixed to the shaft end with two 4-40 or M2.5 screws on a 36.45 mm (1.435 in) bolt circle, directly or through a rotor adapter, with a total indicated runout of no more than 0.025 mm (0.001 in). Stranded wires of 28 or 30 AWG, 24 AWG at most, run along the shaft or through its bore and are secured to it before being soldered to the rotor terminals. The S-Series user manual describes the mounting. Except on the Short S4/TG, the stator is held by a tether on its tabs, a flexible cable or a soft spring.
It is primarily used on engines in vehicles, where space is limited and conditions are hot, fast and vibrating: see measurements in limited space and accessory belt pulley torque.
Short S4/D and S4J: four circuits, stub rotor
The Short S4/D and Short S4J are four-circuit Short S slip rings whose rotor is a stub instead of the 41.28 mm flange, with the rotor wires leaving along the axis, as their outline drawings show. The stub of the Short S4J is notched. The four circuits are rated at 500 mA through precious metal rings and brushes, with a peak resistance variation of 0.1 Ω, and the stainless steel and aluminum case is sealed against dust.
They are ordered as Short S4/D or Short S4J, with end terminals on the stator; Short S4/T/D, with stator terminals; or Short S4/X/D, with a miniature connector on the stator and one 3 m (10 ft) cable. The part number guide explains the suffixes.
The stub is not mounted like the flange rotor of the other Short S models; its outline is shown in the configurator below. Ask us for the mounting of a stub rotor on your shaft.
It is primarily used on engines in vehicles, where space is limited and conditions are hot, fast and vibrating: see measurements in limited space.
Short S4/TC1: four circuits, one rotor-mounted thermocouple amplifier
The Short S4/TC1 combines the four-circuit Short S slip ring with a thermocouple amplifier built into its rotor, between the thermocouple and the rings, so the signal crosses the rings as a high-level voltage. Its four circuits are rated at 500 mA through precious metal rings and brushes, with a peak resistance variation of 0.1 Ω, and the stainless steel and aluminum case is sealed against dust. The rotor is 41.28 mm (1.625 in) in diameter.
It is ordered as Short S4/T/TC1K, for a type K thermocouple, or Short S4/T/TC1T, for type T, both with stator terminals. The part number guide explains the suffixes.
The rotor is fixed to the shaft end with two 4-40 or M2.5 screws on a 36.45 mm (1.435 in) bolt circle, directly or through a rotor adapter, with a total indicated runout of no more than 0.025 mm (0.001 in). The stator is held by a tether on its tabs, a flexible cable or a soft spring.
It takes thermocouple temperatures off a rotating part where space is limited: see temperature on rotating components and measurements in limited space.
