Panel-mount keyboard

capacitivefor control panelsRS-232

Overview The demand for high‑tech design and more intuitive human‑machine interfaces is driving the market toward elegant, user‑friendly control panels. Using CTK (capacitive transparent keyboard) technology, complete touch keyboards are produced including graphic panel, capacitive sensor and plastic electronic control cover. These assemblies are typically delivered ready for user installation and can communicate with machines via interfaces such as RS-485, RS-232, CAN-bus, open collector output or dry contact.
