OF50

Product catalog summary

General Specifications:
The document outlines the specifications for the OF50 oil-filled potentiometer, which is a wirewound bushing mount model. It includes standard resistance values ranging from 100Ω to 20kΩ, with additional options up to 50kΩ. The potentiometer is available in both standard and precision classes, with tolerances of ±10% (K) for standard and ±5% (J) for precision. Power rating is specified at 0.5W.

Performance Parameters:
Key performance parameters include a temperature coefficient of ±20 ppm/ºC, insulation resistance over 100MΩ at 1,000 V.D.C., and dielectric strength of 1 minute at 1,000 V.A.C. Mechanical specifications include a rotational angle of 280º ±5º and a torque requirement within 30mN∙m (300gf∙cm).

Construction Details:
The potentiometer features a shaft diameter of ø6.35mm with options for special machining and extensions. It supports extra taps and multi-ganged configurations. The resistance wire used is either Cu-Ni or Ni-Cr system.

Additional Information:
Standard dimensions and mounting details are provided, including the attachment of inner teeth washers and hex nuts. The document notes that specifications are subject to change without prior notification.
