The 9000 Series is ideal for those applications that demand proportional control with the lowest possible profile below the panel. Developed from the proven 7000 Series, the 9000 Series employs the same, highly proven, contactless, inductive sensing and circuitry. The mechanics have been radically improved to reduce the below-panel depth to a world class 35mm sub-panel or 31mm drop-through. This joystick offers self-centering, omni-directional functionality, and utilises the exclusive ‘locking cam’ system to rigidly secure the highly repeatable mechanism around the precision ground steel operating shaft. High precision air wound coils are mounted directly onto the SMT circuitry, delivering enviable accuracy whilst further minimising the installed depth of the joystick.

The 9000 Series joystick operates by passing a oscillating current through a drive coil, directly mounted at the lower end of the operating lever, and immediately above the four sensing coils. When the shaft and drive coil moves away from the centre, the signals detected in each opposing pair of coils increase nominally in proportion to deflection. The phase of those signals determine the direction. Synchronous electronic switches followed by integrating amplifiers provide DC signals directly equivalent to those of potentiometer joysticks, but with fixed output impedance and free of wiper noise
and track wear.

Designed for use in the most safety-critical applications, the 9000 Series incorporates comprehensive internal monitoring circuitry whereby output signals are continually compared with separately generated ‘mirror signals’. In the unlikely event of an internal fault, the dual decode system will generate a separate fault signal, enabling the
controller to fail-to-safe. The dual decode system is a complete internal self-monitoring system, providing a far higher standard of protection. An additional,‘away from centre’ signal is also available whenever required. Although the monitoring of the joystick is fully internal, the inverse ‘mirror signals’ can be available as external outputs where the monitor function is incorporated within the controller circuitry.

The 9000 Series may also be specified with guided feel. A joystick with guided feel moves more readily towards the poles ( N, S, E and W ) and whilst it can still move away from the poles, the force required to do so is greater. Unless specified otherwise, joysticks are supplied as standard without guiding. This standard configuration allows the user to move the joystick anywhere within the limiter with the same force and without any bias.

Deliberate signal interaction - Enables reduction in one signal as the other increases. This option is particularly beneficial where it is undesirable to maintain full forward speed while turning and vice versa.
