4000 series
Industrial resistive joysticks
Overview
MECHANISM
Unlike most other products in it's class the 4000 series employs an all-metal mechanism, providing the finest
feel. It delivers consistent return to center performance over life, across a broad range of applications and
operating environments. The 4000 series is offered in two body styles; the more standard closed body type
should be selected for those applications requiring standard single or dual axis functionality. The open frame
variant may be specified for those applications requiring friction hold functionality, additional center detect
microswitches or where the above the panel height must be kept to a minimum. In case an open frame joystick
is specified with a standard (5) boot, a bezel must be also used. Both body styles employ the same mechanism
and therefore provide the same performance and feel.
POTENTIOMETERS
The high quality plastic film potentiometers employed as standard in the 4000 series have 340° tracks. With a
shaft deflection angle of 55° (±27.5°), a typical 12V supply would therefore result in a full-scale nominal
deflection from 5V to 7V, operating about a nominal 6V center. The 4000 series is available with alternative
potentiometers, including the option of the 5K-55° track variant, providing rail-to-rail signal swings for
applications where these are necessary and additional amplification is not practical. The potentiometers on the
4000 series are designed for use as a variable potential divider rather than a two pin variable resistor. Noise
generated by the contact resistance of the wiper to the track dictates that for optimum performance the output
signals should be fed into a load of greater than 100K.
Potentiometer Option 9 is to special order only, and may be subject to longer than standard lead times.
PANEL CUT-OUT
Being a sub-panel mount joystick the panel cut-out may be used to limit the deflection of the joystick. The
maximum allowable panel cut-out dimensions are shown on the following page. Where some handles may be
larger than the specified panel cut-out please refer to the APEM sales team. Subsequently the joystick may be
supplied without the handle fitted, or with an additional mounting plate.
SPRINGING
As standard 4000 series are offered sprung to center. The standard spring force requires 1.3N (nominally) to
off-center the joystick. The 4000 series may be specified with a lighter spring (1N), or a stronger spring (1.6N).
N.B. Forces quoted are subject to exact joystick configuration and are provided as a guide only.
The 4000 series also offers a friction hold configuration, whereby the handle will remain in the position it is left
when no operator is present. The amount of friction may be varied prior to installation by adjusting the torque
setting of the friction clutches.
SEALING
As standard, the 4000 series is sealed to IP65 above the panel. This may be subject to exact configuration
selected. Some configurations will yield an IP67 seal. Please refer to APEM for details of your chosen mounting,
handle and boot options and for guidance as to the best level of panel seal achievable.
