Zip Code: 410126 CK-TR7878-50M2: IP65 Sealed 50mm Medical & Industrial Trackball Module The CK-TR7878-50M2 is a rugged IP65 waterproof sealed 50.0mm mechanical trackball module, purpose-built for medical B-ultrasound devices and high-reliability industrial control systems. Featuring a 77.7mm x 77.7mm panel size and integrated mounting holes, this fully sealed trackball delivers ultra-silent rolling, dynamic high-precision positioning and long-term structural durability. It acts as a stable, plug-and-play human-machine interface solution for medical, marine, military, aviation and harsh manufacturing environments. Equipped with a high-quality 50.0mm mechanical trackball and premium bearing rolling system, the CK-TR7878-50M2 provides ultra-smooth, noise-free operation even during round-the-clock continuous operation. Designed with standard mounting holes, it supports fast, secure and flush panel mounting for various embedded equipment. Boasting an ultra-long mechanical life of over 10 million cycles and an average service lifespan of more than 6 years, this trackball features superior fatigue resistance. With an MTBF of over 50,000 hours and an MTTR of less than 30 minutes, it effectively reduces equipment failure risks and lowers long-term maintenance costs. It integrates a professional 3-button circuit that supports independent left-click, right-click and scroll functions, with accessible external button ports to meet diverse operational and equipment design needs. Adopting advanced Rate Sensitive Dynamic Resolution technology, the module realizes intelligent cursor speed adjustment: fast rolling accelerates cursor movement for efficient large-area navigation, while slow micro-operation retains precise one-pixel positioning, perfectly fitting high-precision medical diagnosis and industrial parameter fine-tuning scenarios. The CK-TR7878-50M2 supports one optional single interface to suit different host requirements: USB or PS/2 or RS232 or Square wave for optional. Customers can select the exclusive interface that matches their device configuration, ensuring targeted compatibility and stable connection without redundant functions. Featuring true plug-and-play design, no complicated driver installation or professional debugging is required, greatly simplifying equipment integration, on-site upgrading and daily maintenance workflows. This trackball module achieves full cross-platform system compatibility, supporting all mainstream operating systems including Windows full versions, Linux, Unix, Mac OSX, Vxworks and Android. It can be seamlessly embedded into medical diagnostic
