KY-3688LP-B Metal Keypad With LCD Screen and Optional Braille

KY-3688LP-B is an embedded metal keypad that combines 12 stainless steel buttons with a 122*32 LCD screen in one panel.

Product Overview

KY-3688LP-B is an embedded metal keypad that combines 12 stainless steel buttons with a 122*32 LCD screen in one panel. It is aimed at self-service builds where the user needs to read a prompt and enter a code at the same point, such as outdoor battery operated parcel lockers. Braille is available as an option so the same terminal can serve sighted and non-sighted users.
  • 12 buttons and a 122*32 LCD in one assembly removes a separate display cutout and harness
  • SUS304 brushed stainless steel panel is explosion-proof and corrosion-resistant for outdoor lockers
  • Braille is optional, so accessibility can be added without a new tooling program
  • Etched key legends are made to the customer artwork rather than chosen from a fixed set
  • Layout can be customized for financial, communications and military self-service cabinets
  • Embedded format drops into existing panel designs as a single module

Plastic locker keypadSUS304 brushed stainless is explosion-proof and corrosion-resistant where moulded plastic fades and cracks outdoors

Use Guide

  1. Size the panel cutout around both the 12 key field and the 122*32 LCD window
