Multiturn-Wirewound Potentiometer 46HDS

Precision potentiometer with servo flange 

The 46HDS series was specially developed for applications that require maximum precision and load capacity. With a rated load capacity of up to 10 W (for the 20-turn version) and the ability to measure up to 30 revolutions (up to 10800°, on request), this potentiometer is ideal for industrial control systems and high-performance machines.

Another option is the single-wire version, which is available on request for resistance values from 0.5 to 20 ohms. Thanks to the continuous wire path, this variant enables an almost infinite signal without discrete steps or jumps. This allows extremely fine position measurements and is particularly suitable for applications that require the highest precision, such as in metrology or precision mechanics.

Limit switches can be configured to limit rotary movements either outside or inside the electrically effective angle of rotation:

• Circumscription (standard): limit switches are activated outside the electrically effective angle of rotation (360° × n)
• Inscription type (option): Limit switches are activated within the electrically effective angle of rotation (360° × n) to precisely limit signal plateaus

Limitations are available in different variants:

• E1: Limitation in the CCW direction
• E2: Limitation in the CW direction
• EE: Limitation in both directions

Thanks to the robust design with a 46 mm aluminium housing and a service life of 2 million revolutions (20 turns), the 46HDS series offers reliable performance even under demanding conditions.
