Why choose this product?
The wire design is suitable for applications requiring stability and mechanical resistance.
A wide range of resistance values makes it easy to select for a specific connection.
Panel mounting with shaft is practical for integration into devices and control cabinets.
The operating temperature range allows use even in technically more demanding conditions.
The nominal power of 1 W is suitable for common control and adjustment tasks.
Installation and operating instructions
When selecting a resistor variant, it is necessary to take into account the required control range and power load in the circuit.
Install the potentiometer in such a way that there is no mechanical stress on the terminals or shaft.
For proper function, we recommend checking the connection of the end terminals and the runner before commissioning.
When soldering, it is advisable to limit the time of thermal stress on the pins to the necessary minimum.
Safety notice
The maximum permissible operating voltage must always be assessed with respect to the specific resistance value and power loss in the application.
If the component is used in circuits with hazardous voltage, installation must be performed by a qualified person.
When operating in devices with voltages above 60 V DC or in network applications, it is necessary to ensure adequate insulation, shielding and protection against touching live parts.
