Arestech TPM-3212 12.1" XGA Industrial Touch Monitors with IP54 Panel Mount and PCAP or Resistive Touch

Many machine and kiosk builds need a plain, reliable touch screen that fits a cut-out, takes a VGA feed from the controller and runs from the same 12 or 24 V supply as the rest of the panel. The Arestech TPM-3212 series is built for that: a family of 12.1 inch industrial touch monitors with a 450 nit 4:3 XGA LCD at 1024 x 768, a 700:1 contrast ratio and 160° viewing angles horizontally and vertically, rated IP54 so dust and splashing water stay out when the monitor sits in a cabinet door or kiosk front.

Every TPM-3212 shares the same build. Video arrives on a single VGA input, power is 12 to 24 V DC from a single source on a two-pin Phoenix terminal block, drawing 6.8 W typical, and the 12.1″ monitor measures 319.6 x 253.6 x 37.6 mm for a 301 x 235 mm panel cut-out, with 75 x 75 and 100 x 100 mm VESA holes as an alternative. It operates from -20 °C to 60 °C at 5 to 95% humidity and is vibration-tested from 5 to 500 Hz at 2.16 Grms.

The TPM-3212 series splits on touch. The TPM-3212P uses a projected capacitive touch screen with a 7 Mohs surface and 90% transparency, connected over USB, for multi-touch bare-finger operation. The TPM-3212R uses a 5-wire resistive touch screen with a 3 Mohs surface, 80% transparency and a rating of 10 million touches, connected over USB or RS-232, which suits gloved operators and older controllers with a serial touch interface. Both models share the same cut-out and mounting, so a machine range can standardize on one panel and choose the touch technology per customer.

Arestech names embedded HMI displays, factory automation, ATMs and self-service kiosks, and vending and ticketing machines as the target applications for the TPM-3212. Our white paper on choosing the right touch technology compares projected capacitive and resistive screens for industrial use, which is usually the deciding question between the two 12.1 inch models. Where the screen faces daylight, the SM-112(P)(R)/VM-2100 is the sunlight readable equivalent, and the TPM-3615 family covers stainless steel washdown installs.
