PCAP touch monitors (TC series): the technology explained

What projected-capacitive (PCAP) touch technology is, why it replaced resistive screens, and when the TC series (TC-185F, TC-215F, TC-238F) is the right fit for POS, self-service, and HMI.

Everyone knows the difference without knowing the words: a phone-like screen that responds instantly to a fingertip, versus an old terminal you press hard and hope. The first is projected-capacitive (PCAP) touch; the second is usually aging resistive technology. For public-facing and operator screens, that difference decides how the system feels every single day.

How PCAP works

A PCAP sensor is a grid of transparent electrodes behind glass. A fingertip changes the local capacitance, and the controller triangulates the touch — no pressure, no moving layers, and 10-point multi-touch as standard. Because the sensor sits behind tempered glass, the front is flat, durable, and easy to clean.

The TC series

The TC family are PCAP touch monitors built for commercial integration: [TC-185F](/product/tc-185f) (18.5"), [TC-215F](/product/tc-215f) (21.5"), and [TC-238F](/product/tc-238f) (23.8") — FHD panels with 10-point multi-touch, HDMI and VGA inputs, USB touch interface (driverless on Windows and mainstream Linux), VESA 100×100 mounting, and 12V DC power for clean kiosk integration.

  • POS and checkout — responsive touch keeps lines moving; the glass front survives retail cleaning.
  • Self-service — pair with a NANO mini PC inside the enclosure for a complete kiosk.
  • Light-industrial HMI — where the environment does not demand a sealed panel PC, a touch monitor plus cabinet PC is the flexible option.
