Potentiometers

www.DataSheet4U.com Industrial-Grade Potentiometers AW360 ZE Series In addition to direct analog applications, the AW360 ZE can be used in conjunction with an external A/D converter. In these applications, the AW360 ZE operates as an angle transducer with 12-bit resolution and 10- or 11-bit absolute accuracy depending on model selected. Only six connections are required and these are made via a 6-pole, waterproof plug and socket. Special features • gap-free output over all 360° • very high absolute linearity • interchangeable without electrical adjustment • guaranteed 12-bit resolution and repeatability • long life – 50 x 106 movements • protection class IP 65 The anodized aluminum housing is in compliance with protection class IP 65 with a conformable plug making the AW360 ZE particularly suited to the stringent requirements found in heavy manufacturing environments. The AW360 ZE provides absolute 360º angle encoding in heavyduty industrial environments. Unlike single-wiper potentiometers that have a dead band, the AW360 ZE has two wipers and hybrid circuitry to provide a full 360º measurement range. The reset voltages at the beginning and end of the saw tooth are well defined and the function-angle tolerance normally associated with potentiometers is eliminated. The transducer delivers a logical signal separately from analog output. This signal can then be used to inhibit A/D conversion during the reset period to avoid measuring errors. These features together with the fact that the maximum output voltage is determined by the applied voltage means that the units may be interchanged or replaced without the need for electrical adjustment or trimming.
