SE2002-DC70A thermal printhead uses high performance partial glaze and highly conductive overcoat layer to achieve high speed, high quality and high durability. SE200*-DC70A series are lined up which can accommodate with all types of barcode labeling printers from Direct to Thermal Transfer, normal to high speed (over 300mm/s).
The SE2002-DC70A is a high‑speed thermal printhead developed by ROHM. It uses the company’s STEP FREE structure and a high‑hardness W‑coat protective layer, providing excellent corrosion resistance, scratch resistance and durability. The printhead is compatible with a wide range of barcode, label, packaging, ATM and ticket printers, and can operate at speeds exceeding 300 mm/s.
Technical details include external dimensions, pin assignments, an equivalent circuit diagram, and a set of electrical and mechanical characteristics such as a 150 km abrasion life, an effective print width of 66 ± 0.5 mm, and a maximum clock frequency in the MHz range. The document also contains application notes and legal disclaimer information. This manual is written in Chinese.
