PART NO.: CK-TR7878-50M CK-TR7878-50M: IP65 Sealed 50mm Medical & Industrial Trackball Module The CK-TR7878-50M is a rugged IP65 waterproof sealed 50.0mm mechanical trackball module, professionally designed for medical B-ultrasound equipment and a wide range of high-reliability industrial control systems. Featuring a 77.7mm × 77.7mm panel dimension and reserved mounting holes, this fully sealed trackball delivers noise-free operation, precise dynamic positioning and industry-leading durability. It serves as a reliable, plug-and-play human-machine interface solution for medical, marine, military, aviation and harsh manufacturing environments. Silent Rolling & Long-Lasting Mechanical Performance Equipped with a premium 50.0mm mechanical trackball and high-precision bearing structure, the CK-TR7878-50M ensures ultra-smooth, completely silent operation even during prolonged continuous use. The practical mounting hole design enables fast, secure and stable panel installation for various embedded devices. Engineered for extreme durability, the trackball supports over 10 million operating cycles with an average service lifespan of more than 6 years. With an MTBF exceeding 50,000 hours and MTTR lower than 30 minutes, it minimizes equipment downtime and reduces overall maintenance costs for long-term industrial and medical applications. Integrated with a complete 3-button circuit, the module supports independent left-click, right-click and scroll functions, with accessible ports for external mouse button connection to meet diverse operational requirements. Adopting Rate Sensitive Dynamic Resolution technology, it delivers intelligent cursor speed adaptation: fast trackball movement accelerates cursor travel for quick navigation, while slow rolling maintains accurate one-pixel positioning, perfectly suiting high-precision medical diagnosis and industrial parameter fine adjustment scenarios. Optional Single Interface & Hassle-Free Plug-and-Play The CK-TR7878-50M provides one optional single interface to match different host devices: USB or PS/2 or RS232 or Squarewave for optional. Customers can select the exclusive interface that fits their equipment, avoiding redundant configurations and ensuring stable and targeted compatibility. Featuring true plug-and-play functionality, no complex driver installation or professional debugging is required, greatly simplifying on-site integration, equipment upgrading and daily maintenance work. This trackball module offers full cross-platform 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
