PART NO.: CK-TR7171-50M2 CK-TR7171-50M2: IP65 Sealed 50mm Medical & Industrial Trackball Module The CK-TR7171-50M2 is a rugged IP65 waterproof sealed 50.0mm mechanical trackball module, purpose-built for medical B-ultrasound systems and high-reliability industrial control applications. Featuring a 70.6mm × 70.6mm panel size, integrated mounting holes, silent bearing operation and industry-proven durability, this sealed trackball delivers precise, stable and long-lasting human-machine control. It is an ideal plug-and-play solution for medical, marine, military, aviation and harsh manufacturing environments. Silent Operation & Industrial-Grade Mechanical Durability Equipped with a high-quality 50.0mm mechanical trackball and premium bearing rolling structure, the CK-TR7171-50M2 provides ultra-smooth, noise-free operation even during round-the-clock continuous use. The reserved mounting hole design enables quick, secure and flush panel mounting for various embedded devices. Boasting a mechanical lifespan of over 10 million cycles and an average service life of more than 6 years, this trackball delivers outstanding fatigue resistance and long-term stability, greatly reducing equipment downtime and maintenance frequency. It comes with a built-in 3-button circuit that supports left-click, right-click and scroll functions, with accessible ports for external mouse button connection to fit diverse operational habits and equipment designs. Adopting Rate Sensitive Dynamic Resolution technology, the module achieves intelligent cursor dynamic adjustment: fast rolling accelerates cursor movement for efficient large-area navigation, while slow micro-operation retains accurate one-pixel positioning, perfectly matching high-precision medical diagnosis and industrial parameter fine-tuning scenarios. Customizable Single Interface & Plug-and-Play Simplicity The CK-TR7171-50M2 supports one customizable single interface for selection: USB or PS/2 or Square wave for optional. Customers can choose the exclusive interface that matches their host device, avoiding redundant functions and ensuring highly targeted compatibility. With plug-and-play functionality, no complex driver installation or professional debugging is required, simplifying on-site integration, equipment upgrading and daily maintenance. Widely compatible with cross-platform systems, this trackball supports Windows full series, Linux, Unix, Mac OSX, Vxworks and Android operating systems. It can be seamlessly adapted to medical diagnostic equipment, industrial control consoles, marine simulation systems, ship cabin terminals, military and aviation devices, realizing stable and reliable HMI control for multiple professional scenarios.
