Industrial Smart Terminals

Engineered for permanent industrial integration, the K-Smart Series delivers fixed rugged terminals designed for continuous infrastructure operations. By eliminating internal batteries and utilizing direct DC/wide-voltage inputs, these platforms remove the maintenance risks of battery failure in extreme temperatures (-31°C to +70°C). Featuring native RJ45, RS232, and GPIO interfaces, K-Smart terminals serve as the reliable HMI backbone for EV charging stations, heavy machinery, and automated manufacturing.
