Finger Joystick
Series 844
Specications are subject to change without notice
Very robust joystick
Small installation depth of < 20 mm
Wide selection of congurations/handles
Contact-less, wear-free Hall e󰀨ect technology
Reliability through redundant Hall sensors (optional)
Ideally suited for applications with high mechanical demands
The series 844 o󰀨ers the most robust nger joysticks in the
portfolio and is suited for harsh conditions. The series uses
modern Hall e󰀨ect sensors, and exhibits robust mechanics
(max. load 400 N) with up 10 million lifecycles. A special feature
are the Center Detect and Center Tap outputs for non-redundant
versions. Moreover, many di󰀨erent handle designs are available.

*The output voltage is ratiometric to the supply voltage. We therefore suggest to use low-noise, stabilized power supplies.
Magnetic screening
The 844 series incorporates internal magnetic screening to minimize the e󰀨ect of external magnetic elds. Nevertheless, we
do not recommend mounting or operating the joystick close to strong magnetic elds.
Mechanism
The omni-directional mechanism features an extremely robust ball-socket pivot. This construction yields a product that is very
resistant to vertical impact, and constantly withstands high pull, push, rotational or horizontal forces.
