Description
Danfoss has developed the JS120 to meet the harsh operating requirements of today’s mobile machine
market.
Developed for applications where ergonomics and system integrity are paramount, the JS120 is a
minimum width, low profile joystick that provides precise fingertip control in one axis. The low profile
lever makes the JS120 less susceptible to unintentional operation and the minimum under-panel
footprint makes it ideal for mounting in panels and operator arm rests. The JS120 is sealed to IP 66 above
panel to enable it to operate in extreme environments.
Designed for use with electronic controllers, the joystick generates analog and switched reference signals
proportional to the distance and direction over which the handle is moved. The output is configured to
provide signals for fault detection circuits and a center tap provides an accurate voltage reference for the
lever in its released position, or a zero point for a bipolar supply voltage. Electrically independent
direction switches are also available.
This publication describes the technical features and data required to specify the JS120 base for your
application.
