KA2002-BE10A is a 2.7V thermal printhead for mobile, FET-POS, debit card, PDA, and ECR devices developed by ROHM. The low voltage allows it to be powered by a single lithium battery, which contributes to the miniaturization of the end product.
This manual describes the KA2002-BE10A thermal printhead, highlighting its low‑voltage operation (under 8.5 V) and suitability for mobile, EFT‑POS, hand‑held, and debit printers. It outlines the B series features such as reduced height, enlarged paper pathway, and 2.7 V circuit draw for battery‑powered designs.
The document includes an equivalent circuit diagram, detailed pin assignments, timing charts, electrical characteristic curves, and a full set of specifications such as effective printing width, dot pitch, power consumption, and operating temperature. An appendix provides legal notices and contact information.
