Data Sheet for Precision PotentiometerMultiturn Wirewound Potentiometer The ALI(R)17/19 potentiometers in 22 mm housing are suitable for applications where a precise multiturn potentiometer increased radial shaft loads is important. ■ Robust design for radial shaft load up to 4N ■ Simplified installation due to connector version ■ Versions ALIR17/19 with integrated slipping clutch ■ With many options The potentiometer ALI(R)17 / ALI(R)19 (06,35 / 06,00 mm) enables operation with a radial shaft load of up to 4N. The low-wear polymer bearing in the lid provides more stability and makes the potentiometer particularly robust. In addition, an optional integrated slipping clutch protects the potentiometer from damage by overrunning the end stops and facilitates the zero point adjustment. There is a screw driver slot at the top of the shaft for adjustment purposes and the potentiometer is available in 3-, 5- and 10-turn versions (optional in 1,2, 4, 6, 7 or 8 turn). The radial gold-plated connection pins are suitable for flat connectors (2.8 mm according to DIN 46247 part 3) and the connector version simplifies the mounting.
