JOYSTICK CONTROLLERS

FINGER OPERATED

Innovative design

The Penny+Giles joystick range are displacement industrial joysticks that provide electricalsignals in direct proportion to the movement of the lever. Two different types ofsensing technology are utilised in the finger operated controller range. The JC025, JC030, JC100, JC120 and JC400 models use long life potentiometertracks with directional/center switching, and the JC2000 model uses non-contact Halleffect sensors. Potentiometric sensing Designed to interface with an electronic controller, the long-life potentiometer tracks generate analogue outputs withswitched reference signals that are proportional to the distance and direction over which the handle (or rocker) is moved. The analogue output can be factory configured to provide signals for fault detection circuits and a center tap provides anaccurate voltage reference for the center position or a zero point for a bipolar supply voltage. An electrically independentswitch operates with separate contacts each side of the joystick center position, in each available axis. The key advantages of this technology are its linear output and the versatility it derives from its simplicity; it consists of acarbon-based potentiometer track with no complex circuitry or electronics, so it is not susceptible to electromagneticinterference or magnetic fields. However, as a contacting device it does have a long, but finite, life and due consideration should be given to applications subject to high intensity use or where high dither or vibration may be encountered. Hall effect sensing The JC2000 model uses non-contact Hall effect sensors to provide one, two orthree axes of precision fingertip control, with dual independent outputs in the single and dual axis models for built-in redundancy and increased reliability.The key advantage of using Hall effect sensors is that they offer very longlife because they have no contacting parts. They allow a very compact under-panel depth - as much as half the space of comparablepotentiometer designs. Hall effect joysticks are more sensitive toelectromagnetic interference, but this has been minimised by using appropriate industrial shielding and robust circuit design for all but the mostdemanding environments.
