PART NO.: CK-TR7373-50M1 CK-TR7373-50M1: IP65 Sealed 50mm Multi-Interface Medical & Industrial Trackball Module The CK-TR7373-50M1 is a heavy-duty IP65 waterproof sealed 50.0mm mechanical trackball module, specially optimized for medical B-ultrasound devices and diverse high-reliability industrial control systems. Adopting a 73.0mm × 73.0mm panel size and integrated mounting hole design, this fully sealed trackball features silent rolling, ultra-long mechanical lifespan and flexible customizable single interfaces. It delivers stable, precise and fatigue-resistant human-machine control, serving as a premium plug-and-play HMI solution for medical, marine, military, aviation and harsh manufacturing scenarios. Silent Operation & Industrial-Grade Mechanical Durability Built with a high-quality 50.0mm mechanical trackball and precision bearing rolling structure, the CK-TR7373-50M1 achieves ultra-smooth, completely noise-free operation even during 24/7 continuous working cycles. The reserved mounting holes enable fast, firm and flush panel installation, compatible with various embedded equipment layouts. Boasting an outstanding mechanical lifespan of over 10 million cycles and an average service life of more than 6 years, the module features excellent structural stability and anti-fatigue performance. With an MTBF of over 50,000 hours and an MTTR of less than 30 minutes, it effectively reduces equipment downtime and long-term maintenance costs. Equipped with a professional 3-button circuit, it supports independent left-click, right-click and scroll functions with accessible external button connection ports, fully meeting diverse operational habits and equipment design requirements. Powered by Rate Sensitive Dynamic Resolution technology, the trackball realizes intelligent cursor speed switching: fast rolling accelerates cursor movement for efficient large-range navigation, while slow micro-operation retains accurate one-pixel positioning, perfectly adapting to high-precision medical diagnosis and industrial parameter fine-tuning work. Customizable Single Interface & Universal Plug-and-Play The CK-TR7373-50M1 supports one customizable single interface for optional selection: USB, PS/2, RS232 or square wave. Customers can choose the exclusive interface that perfectly matches their host device, achieving targeted and highly stable compatibility without redundant functions. Featuring true plug-and-play performance, no complex driver installation or professional debugging is required, greatly simplifying equipment integration, on-site upgrading and daily maintenance. This trackball module supports full cross-platform system compatibility, covering all mainstream operating systems including Windows full versions, Linux, Unix, Mac OSX, Vxworks and Android. It can be seamlessly embedded into medical diagnostic
