Frequently Asked Questions

Find answers to the most frequently asked questions about our products and services.
How can customized potentiometers be ordered?

Customized potentiometers can be specified using a detailed order code that includes segments for nominal resistance, linearity, electrical travel, mechanical options, and compliance. Contact technical support for assistance with specific configurations.

What are the starting torques for rotary potentiometers?

The starting torques range from ≤ 0.1 N.cm for miniature models to ≤ 5 x 10–3 N.m for models with precision bearings.

What types of potentiometers are available in this series?

The potentiometer series includes single-turn rotary potentiometers, multi-turn rotary potentiometers, rectilinear potentiometers, and pancake potentiometers. These are designed to suit a wide range of applications from precise position sensing to control systems.

What are the core technologies used in these potentiometers?

The core technologies include wirewound, conductive plastic, and hybrid elements, providing various performance characteristics such as high resolution, long life, and excellent linearity.

How are the potentiometers tested for quality and performance?

Potentiometers undergo rigorous testing, including:

  • Micro-linearity and scale factor measurements
  • Vibration and shock testing
  • Environmental testing for thermal cycling, humidity, and salt fog resistance
How do these potentiometers perform under vibration and shock conditions?

These potentiometers are designed to withstand high levels of vibration and shock:

  • Vibration resistance: up to 20 g, 1.5 mm, 10 to 500 Hz
  • Shock resistance: up to 50 g, ½ sine, 11 ms
  • General Technical Data
