4.75″ W x 2.65″ H x .501″ D


  • Operating Temperature: -20 to 70° C; the LCD temperature range primarily limits this
  • Storage Temperature: -30 to 80° C
  • Humidity: Max 90%RH at 60° C; No Condensation
  • RoHS 2 Compliant: Yes

Power Requirements

  • Power Supply Voltage: +5VDC±10%
  • Power Consumption: Max 400mA


The board mounting holes connect to a digital ground. These must be connected to a chassis ground either directly or through a transient protection diode for ESD. The resistive touch circuit has ESD protection that shorts ESD on the touch panel to the board mounting holes.

Mounting Options
