SHEC Industrial Thermal PrintHead 300dpi

SHEC 3U105-8529 is a 300dpi thermal print head designed for high-precision industrial-grade printing. It adopts Japanese precision manufacturing technology and performs excellently in scenarios such as medical diagnosis, precision labeling, and electronic component marking. Its core features can be summarized as follows:

Ultra-fine dot matrix control: 5.67 dots/mm heating point density, achieving 40% improvement in edge sharpness of printed products (compared to 200dpi models)

Nano-level thermal response: using a new aluminum nitride ceramic substrate, the thermal conductivity efficiency is 25% higher than that of traditional materials

Military-grade durability: passed 1000 hours of salt spray test and 500,000 times of impact vibration test
