Product catalog summary

Overview: This document provides technical specifications and features for a range of potentiometers manufactured by Contelec AG, a company of the Siedle-Group. The document includes details on electrical and mechanical data, standards, applications, features, options, and ideal wiring practices for potentiometers.

Electrical Data: The potentiometers have nominal resistances of 1, 5, or 10 kOhm with a resistance tolerance of ±20%. They feature independent linearity ranging from ±0.25% to ±2% of the measurement range, depending on the model. The electrical angle varies from 2160° to 34560°, with repeatability between 3.24° and 3.46°. The temperature coefficient of the voltage divider is 50 ppm/°C, and the recommended wiper current is a maximum of 1 µA, with a malfunction current limit of 5 mA. Power ratings are either 0.25 W or 0.5 W at 40°C, with a minimum electrical life of 15 million turns.

Mechanical Data: The mechanical range varies from 6 to 100 turns, with an adjusting speed of up to 1800°/s. The operating temperature range is -25°C to +75°C, and storage temperature is -25°C to +105°C. All models have a protection class of IP65 and a minimum mechanical life of 15 million turns.

Standards: The potentiometers meet standards for insulating resistance (1 GOhm at 500 VDC), dielectric strength (1 kV at 50Hz), vibration resistance (10g), and shock resistance (30g).

Applications: These potentiometers are suitable for use in fork-lifters and other applications requiring precise control.

Features: Key features include small dimensions, a friction clutch on mechanical end-stops, excellent linearity, and very good resolution (better than 0.1%).

Options: Available options include different shaft diameters (6.35 mm and 3 mm), customer-specific cable lengths, tandem-ganged potentiometers, wiper protection resistance, and wire connections.

Ideal Wiring: Potentiometers should be used as unloaded voltage dividers to avoid nonlinearities caused by load and contact resistance.

Accessories: Each model includes a nut (M10x0.75 / SW13) and a serrated lock washer. Dimensions for bushings and shafts are provided for each model.
