Spectrum Sensors and Controls recently introduced a new line of hollow-shaft potentiometers featuring long life and excellent output smoothness.
These potentiometers feature an anodised aluminium, thermo plastic design with diameters ranging from 2,2 cm to 6,6 cm and a rotational life of 5 to 50 million cycles, making them suitable for animatronics, robotics, automotive handicap controls and military joysticks.
The potentiometers have electrical angles from 26° to 355° ±2°, independent linearity range of ±0,5% to ±1,0%, power ratings of 0,5 W to 2 W at 70°C and a maximum output smoothness of 0,1%. They offer a resistance range of 1 k to 20 k ±10%, 360° continuous rotation, and require no wiper installation or phasing. They are available with a triple cup redundant design for high reliability applications and can be specified with or without connectors.
Spectrum’s potentiometers utilise a co-moulded conductive plastic element for a hard smooth surface and greater long-term reliability compared to raised circuit element potentiometers. In Spectrum’s process the termination and resistance materials are simultaneously moulded with the base substrate.
