panel-mount2 inch (50 mm)USB

Overview
Clickin Industrial CK-TR7373-50M2 is a sealed, IP65-rated 50.0mm trackball module engineered for B-ultrasound medical devices and demanding industrial control systems. The module integrates mounting holes for embedded installation and is compatible with medical cleaning protocols, offering stable and precise cursor control in wet, humid or contaminated environments.

Product Description
The CK-TR7373-50M2 is a heavy-duty sealed trackball module for professional medical and industrial applications. It incorporates a 50.0mm mechanical ball in a light color with gasket sealing, industrial-grade PCB, a compact 73.0mm × 73.0mm mechanical footprint, approx. 0.3 kg weight, and standardized mounting holes. Interfaces include USB, PS/2 and square-wave; true plug-and-play across major operating systems. Certified CE, FCC and RoHS.

Key Features

• Embedded trackball for B-ultrasound diagnostic equipment
• 50.0mm mechanical ball in light/white color
• Bearing-based rolling for smooth, quiet operation
• Rate-sensitive dynamic resolution (high speed tracking and 1-pixel precision at low speed)
• IP65 fully sealed design: dust-tight and resistant to low-pressure water jets
• High durability: over 10 million operating cycles
• Three integrated mouse buttons (left, right, scroll); external button connections supported
• Multi-interface support: USB, PS/2, square-wave; plug-and-play
• Wide environmental tolerance: 100% humidity resistant; operating temperature -20°C to +60°C; passes damp heat, dry heat and salt-mist tests (IEC 60512-6)
• High reliability: MTBF > 50,000 hours; MTTR < 30 minutes; industrial-grade PCB

Product Advantages

• Reliability in harsh environments: IP65 sealing, salt-mist resistance and wide temperature range reduce failures and maintenance in medical operating rooms and other demanding settings.
• Medical-grade cleaning compatibility: light-color ball and gasket resist staining and exposure to disinfectants, supporting hygiene protocols.
• Precision and efficiency: dynamic resolution provides fast tracking and fine control for precise positioning; near-silent operation.
• Easy integration and serviceability: standard mounting holes for embedded installation; plug-and-play connectivity; 12-month warranty and rapid repair capability.
• Broad application range: suitable for medical, industrial automation, marine, military, aviation, pharmaceutical, clean room and harsh-manufacturing environments.

Applications
B-ultrasound devices, hospitals, clinical labs; medical consoles; industrial control panels; marine consoles; military and other harsh-environment systems.
