The unit consists of a 50mm optical trackball with removable ball and adjustable tracking force, with self-draining and flush through options and with three IP67 rated push button switches. The whole is mounted on a blackened AISI 316 stainless steel carrier plate and supplied with a silicone sponge sealing the unit onto the customers' panel.
Above features make this trackball unit best suited for extreme dusty environments where cleaning and/or flush through with clear water is required for optimum functionality (f.i. agressive dust like cement dust, etc..) or for salty water environments (f.i. naval navigation etc…). The adjustable tracking force is another advantage for “unstable” working conditions like for instance in the naval navigation.
