CIRCUITRECOMMENDATION
Hybrid track
potentiometers feature a high wiper contact resistance, therefore operational checks
should be carried out only in the voltage divider mode. Hybrid track potentiometers should be
used only as voltage dividers, with a minimum wiper circuit impedance of 100 x track resistance
or 0.5M Ω (whichever is greater). Operation with wiper circuits of lower impedance will degradethe output smoothness and affect the linearity. Can be supplied from 10°to 350°in 10°increments2m or 5m cabled socket assemblies available (rated -25 to +90ºC only)
Operating levers 155 or 230mm. See details on page 7
