OF30 Brochure en

Product catalog summary

Overview: The document provides detailed specifications for the OF30 series oil-filled singleturn wirewound potentiometers by MEGATRON Elektronik GmbH & Co. KG. These potentiometers are designed for precision applications, featuring oil filling for heat dissipation, abrasion cleaning, and protection against moisture and aggressive substances.

Specifications:

Electrical Data: The effective electrical angle of rotation is 280° ±5°, with a total resistance range from 50 Ohm to 20 kOhm and a resistance tolerance of ±5%. The independent linearity is ±0.5%, and the maximum wiper current is 35 mA.
Mechanical Data: The mechanical angle of rotation is 360° without a stop and 300° with a stop. The potentiometer has a lifetime of 0.2 million rotations and a maximum operational speed of 40 revolutions per minute. It features a sleeve bearing and operates within a temperature range of -30°C to +60°C.
Environmental Conditions: The potentiometer is rated IP65 for protection and can withstand vibrations of 15g and shocks of 49g.

Options and Customization: The document mentions the availability of additional options for higher quantities or ongoing demand, such as special electrical and mechanical angles, resistance and linearity tolerances, and the possibility of mounting gear wheels or attaching cable assemblies.

Order Code: The order code section provides a detailed breakdown of the selection options for the potentiometer, including resistance values, mechanical angles, and optional features like center taps and shaft dimensions.

Mechanical Drawings: The document includes mechanical drawings with dimensions in millimeters, illustrating the potentiometer's physical characteristics and connection diagram.

Additional Machining Options: On request, special machining options for the shaft are available, including slots, flats, screw threads, and knurled surfaces.
