Connect a full-size pointing device to a USB-A host without pairing, charging, or installing mouse software. The MATIAS M20BB uses an optical sensor and a right-handed three-button layout for routine navigation in office, education, home, and shared-workstation environments. Its 1 m attached cable reaches a nearby desktop, dock, monitor hub, or notebook USB-A port while keeping the mouse continuously powered. PBT plastic distinguishes the exterior from common ABS mouse housings. This material resists UV damage and provides a stable surface texture for repeated daily handling. An aluminum scroll wheel supplies tactile vertical navigation, and the additional control button functions as a Back command on PC systems. On Mac systems, the control button can be assigned to another function. The mouse has no LED indicator or illumination, making it appropriate where a non-lit peripheral is preferred. OMRON switches rated for 50 million actuations support frequent click use over the service life of the peripheral. The 4.3 x 3 x 1.6 in housing weighs 0.19 lb, providing a compact wired alternative for individual desks and mobile workspaces that retain USB-A connectivity. Windows and Mac compatibility allows one mouse style to remain consistent across mixed endpoint environments.
