Numeric Keypads With Integrated LCD Display

Combined key and screen modules that let a machine prompt the operator and take the reply through a single sealed opening.

Problems This Range Solves

  • Fitting a separate display and keypad means two cut outs and two seals to maintain.
  • Battery powered cabinets cannot carry a display that draws continuously.
  • Prompt text is fixed on generic modules and cannot be changed for a market.
  • Cold installations put a plain LCD outside its working range.

Who Specifies It

  • Locker and parcel cabinet manufacturers needing prompt and entry in one panel.
  • Embedded terminal designers with a single available fascia opening.
  • Equipment builders running the panel from a battery or low power supply.
  • Integrators replacing a screen plus keypad pair with one module.

Where It Is Installed

  • A 16 key module with 128*32 LCD embedded in a front panel mounted terminal.
  • A 128*64 grey white backlit keypad in a battery powered cabinet.
  • A 122*32 yellow green unit on a financial self service machine.
  • A 16 key locker keypad with TFT display on a 155*186 mm fascia.
  • A 128.5*123 mm unit with optional backlit keys and DES or TDES support.

What You Get From This Range

  • Integrated dot matrix LCD in 122*32, 128*32 or 128*64 formats.
  • Yellow green or grey white backlight options.
  • Low power design suitable for battery powered scenarios.
  • Display text customised to customer content over RS232.

What To Specify When You Order

Give us these and the quotation comes back complete rather than with questions attached.

  1. Choose the display resolution from 122*32, 128*32 or 128*64 according to the prompt length.
  2. State the backlight colour required and whether the keys should also be lit.
  3. Confirm the power budget, since low power design supports battery operation.
  4. Supply the display text content to be programmed.
  5. Check the operating temperature, as low temperature use is specified on some models only.
