Potentiometer with cable tail

This standard range of up to 8 W potentiometers with wire-wound resistors show that Ex potentiometers can be small and compact. The external dimensions are approximately the same as those of standard industrial potentio-meter enclosures. Central fixing in a single hole and the standard size of shaft have been included. From the variety of resistors on the market we have chosen the most commonly used types and developed a standard program range. The metal Ex d enclosures are tailored to the dimensions of the resistors and feature a standard 30 mm diameter. The potentiometers have been designed so that the stated nominal capacities can be fully exploited at temperature class T6 or T5 and be deployed in zones 1 and 2. In addition to the standard models all other versions such as tandem potentiometers, potentiometers with microswitches, non-standard shafts or larger resistor diameters can be encapsulated in enclosures of up to 120 mm diameter.
