SPC-21WR2
Series: SPC
The Avalue SPC-21WR2 is a 21.5" Full HD stainless-steel fanless ARM panel PC built for hygienic and washdown environments, powered by the Rockchip RK3568 quad-core Cortex-A55 processor. With a fully stainless-steel front and rear construction and a default 5-side IP65 rating (optional whole-system IP66/69K), it is purpose-built for food, pharmaceutical, and wet industrial applications. The 1920x1080 panel offers 250 cd/m² brightness, a high 3000:1 contrast, and 10-point projected-capacitive touch. It runs Android 11 or Debian 11 on 2GB DDR4 and 32GB eMMC, with USB 3.0, HDMI 1.4 out, Gigabit Ethernet, optional waterproof Wi-Fi/Bluetooth, and an optional M12-connector variant for sealed cabling. Validated vibration/shock/drop testing, VESA/wall/stand mounting, and a wide +12~24V input make the SPC-21WR2 a durable hygienic HMI for harsh, washdown-prone environments.
