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 and up to 50kΩ. The potentiometer is available in both standard and precision classes with tolerances of ±10% (K) and ±5% (J) respectively. It also offers a standard class with ±1.0% and a precision class with ±0.5% tolerance.

Electrical Specifications:
The potentiometer can handle a power rating of 0.5W and has an electrical travel of 280º ±5º or 300º ±5º. It features a high insulation resistance of over 100MΩ at 1,000 V.D.C. and can withstand 1 minute at 1,000 V.A.C. The torque specifications include a maximum of 30mN∙m (300gf∙cm) and an approximate value of 0.9N∙m (9kgf∙cm). The temperature coefficient is ±20p.p.m./ºC.

Mechanical Specifications:
The potentiometer weighs approximately 300g and includes options for extra taps (up to 1 tap), multi-ganged configurations (up to 2 gangs), and special electrical travel. The shaft diameter is 6.35mm with options for special machining and without stopper configurations. The shaft can have front and rear extensions, with the rear shaft measuring 6mm in diameter and 25mm in length.

Additional Information:
The document notes that each potentiometer comes with an inner teeth washer and two hex nuts. The standard dimensions and mounting specifications are provided, including a bushing with inch dimensions.
