402388-11RD

The 402388-11RD potentiometer is an automation product which is manufactured by Allen-Bradley. It is part of the 402388 potentiometer series and its mechanical design life cycles include a mechanical life of up to 10,000,000 minutes and pushbuttons and selector switches that are also rated for long operating lives. Furthermore, its potentiometer parts are rated for up to 250,000 minutes and all its other devices for up to 200,000 minutes. The 402388-11RD potentiometer has a dielectric strength of 2200 Volts for 1 minute. Its mechanical vibration ratings are 10 to 2000 Hertz, with 1.5 millimeters of displacement (peak-to-peak) maximum at 10 G. Additionally, it also has a wire gauge and terminal screw torque mechanical ratings of #18 to 14 AWG and 6 to 8 pounds on an inch.

The 402388-11RD potentiometer has an operating temperature range of -40 to 131 degrees Fahrenheit (-40 to 55 degrees Celsius) and a storage temperature range of -40 to 185 degrees Fahrenheit (-40 to 85 degrees Celsius.) Note that the operating temperatures below freezing are based on the absence of liquids and moisture in the environment. The tolerable humidity levels are 5 to 95% without condensation from 77 to 140 degrees Fahrenheit (25 to 60 degrees Celsius) according to the results of Procedure IV of the MIL-STD-810 C, Method 501.1 cycling test. The 402388-11RD potentiometer has a maximum duty contact rating with a maximum thermal continuous current rating of 24 Amps at 120 Volts AC, and 12 Amps at 24 Volts DC. The motor ratings are 120 Volts AC and 15 Horsepower, 240 Volts AC and 3 Horsepower, and 24 Volts DC and 10 Amps FLA or 60 Amps LRA. Its minimum low energy switching load is 17 Volts DC and 5 milliamps.
