Product catalog summary

Overview
This document provides technical specifications for a series of potentiometers produced by Contelec AG, a company of the Siedle-Group. The products are primarily used in gas pedal applications and are characterized by their compact dimensions, design flexibility, and high cycle life.

Electrical Data
Each model has a nominal resistance of 1 to 5 kOhm with a resistance tolerance of ±20%. The independent linearity is ±1% of the measurement range, and the electrical travel varies from 10 mm to 100 mm depending on the model. The repeatability is 0.05 mm, and the temperature coefficient of the voltage divider is 50 ppm/°C. The recommended wiper current is a maximum of 1 µA, with a maximum wiper current of 10 mA in case of malfunction. The power rating is 0.5 W at 40°C, and the minimum electrical life is 10 million cycles.

Mechanical Data
The mechanical travel ranges from 10 mm to 100 mm. The adjusting force of the push rod is a maximum of 3 N, increasing to 10 N with a return spring. The minimum mechanical life is 5 million cycles. The operating temperature range is -25°C to +75°C, with a storage temperature range of -25°C to +105°C. The protection class is IP65.

Standards
The insulating resistance is 10 GOhm at 500 VDC, and the dielectric strength is 700 V at 50Hz. The products can withstand vibrations of 10 g and shocks of 50 g.

Features and Options
All models feature excellent linearity and resolution, with options for different linearity percentages, nominal resistances, and mechanical configurations such as pass-through push rods, longer push rods, and various bushing options. They can be connected by wires or longer cables and are available in tandem-ganged configurations.

Applications
The primary application for these potentiometers is in gas pedals, where their durability and precision are critical.
