Main Features and Advantages
Unmatched environmental protection: The MATRIX 83PKB-SM sets itself apart with its truly sealed front panel construction . Unlike standard keyboards with gaps between keys that trap contaminants, the MATRIX 83PKB-SM uses a seamless membrane panel with laser-etched legends, achieving NEMA 4X and IP65 ratings . This means the keyboard is fully protected against dust ingress, low-pressure water jets from any direction, and even corrosive chemical splashes . For industries such as food processing, pharmaceuticals, and chemical manufacturing that require regular washdowns of control room surfaces, the MATRIX 83PKB-SM eliminates downtime caused by keyboard failure from environmental contamination .
Integrated industrial control ecosystem: The MATRIX 83PKB-SM functions as an extension of the control console rather than merely an input device . It features 24 dedicated function keys and 8 programmable user keys that can be mapped directly to specific DCS commands, such as opening trend displays, acknowledging all alarms, or toggling between process graphics . This “blind operation” capability allows experienced operators to execute critical commands without diverting their eyes from monitoring screens, dramatically improving emergency response times and reducing the potential for errors during high-stress situations . The MATRIX 83PKB-SM also includes specialized process control keys like ACK (Alarm Acknowledge), SCRL (Scroll), and PAGE navigation that are absent on generic keyboards .
Glove-compatible trackball module: The integrated trackball of the MATRIX 83PKB-SM is specifically engineered for industrial environments. Its robust optical sensor does not require a mousepad and remains unaffected by dirt accumulation that would clog traditional mouse rollers . The large ball and mechanical buttons are designed for reliable operation even when operators are wearing thick safety gloves, a critical requirement in facilities where PPE must be maintained at all times and where touchscreen interfaces are impractical due to glove compatibility issues
