Premium Hall effect joysticks
Overview
A
CENTER DETECT (CD)
Where selected, (configuration 1 types) the output on this additional cable will be 0V while the joystick is inactive. Should either the
X or Y outputs change outside of the center tolerance, indicating that the joystick has been operated, the center detect signal will
switch to 5V. Within the joystick this output is pulled high by a 2K2 resistor and is decoupled by a 100nF capacitor to 0V. This output
is designed for use in applications requiring an enable/disable signal that is separate from the main wipers. It is not recommended
for use as a safety feature or a method of “person-present“ detection.
CENTER TAP REFERENCE (CT)
Where selected, (configurations 1, 3 and 4) the joystick also outputs a center reference voltage that is set at 50% (±1%) of the
supply voltage. This output can be used to check the integrity of the power supply applied to the joystick. A reading on this output,
outside of the specified tolerance suggests a problem with the power supply to the joystick. The other purpose of this output is to
act as a reference equal to the voltage output when the lever is at center. Measuring the voltage outputs relative to CT rather than
0V eliminates inaccuracies created by variation in supply voltage.
GAIN OPTIONS
The voltage output on the wipers, at full scale deflection is determined by the gain. The gain is expressed as a percentage of the
voltage supplied. Therefore (assuming a 5V supply) a joystick specified with ±25% gain would yield 1.25V at South, 2.5V at center
and 3.75V at North. A range of gain options are available as standard for configurations 1, 3 and 4. All joysticks are supplied
pre-set and no further calibration is needed throughout the lifetime of operation.
OUTPUT IMPEDANCE
The voltage outputs at center and at each end of travel are specified across an infinite load, with no current flowing. The output
impedance specified in the electrical specification should be taken into account when designing a system. Load resistance of less
than 10K Ohms is not recommended.
MECHANISM
The omni-directional mechanism utilizes an extremely robust ball-socket pivot. This construction yields an end product that is
extremely resistant to vertical impact. Furthermore it constantly withstands high pull, push, rotational or horizontal forces that the
product may be subject to, during life.
SPRINGING
All 3000 series are offered sprung to center. The standard spring force requires 1.3N (nominally) to off-center the joystick. The
3000 series may be specified with a lighter spring (1N), or a stronger spring (1.6N).
GUIDED FEEL
The 3000 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.
CONNECTIONS
The joystick is fitted, as standard, with 150mm long BS6360 rated cables and an industry standard 2.5mm pitch connector(s).
Further non-standard connectors and cable options are available upon request.
CONFIGURATIONS 1 & 2
Joysticks are supplied with a seven way connector as
standard. If the joystick is specified with a pushbutton
handle, the connector will be nine way.
