Arestech TPM-3212R 12.1″ 5-Wire Resistive Industrial Touch Monitor with XGA LCD and IP54 Panel Mount

On machines and in plant rooms the operator is often wearing gloves, and the controller may be older than the screen and expect a serial touch device. The TPM-3212R is the configuration in the Arestech TPM-3212 series for both cases: a 12.1 inch industrial touch monitor with a 5-wire resistive touch screen, a XGA LCD and IP54 ingress protection.

Resistive touch works by pressure, so it responds to gloved fingers and a stylus, and this screen is rated for 10 million touches with a 3 Mohs surface and 80% transparency. It connects over USB or RS-232. The panel is a 4:3 XGA LCD at 1024 x 768 at 450 nits with a 700:1 contrast ratio and 160° viewing angles horizontally and vertically.

The TPM-3212R takes a single VGA input, so it pairs with controllers, industrial PCs and kiosk computers that have an analogue video output. Power is 12 to 24 V DC from a single source on a two-pin Phoenix terminal block, drawing 6.8 W typical. For bare-finger multi-touch, the TPM-3212P offers projected capacitive touch over USB.

The TPM-3212R measures 319.6 x 253.6 x 37.6 mm, weighs 2.63 kg and fits 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, and the IP54 rating protects it against dust and splashing water. Arestech names embedded HMI displays, factory automation, ATMs and self-service kiosks, and vending and ticketing machines as the target applications.
