AVLE/AVSE   Vandal proof keypads

Both the AVLE keypad and the less expensive AVSE keypad feature vandal-proof aluminum keys with engraved legends. Shoulders formed on the keys prevent them from being removed by force when the keypad is mounted behind a metal panel. Both keypads find application in public places such as telephone and ATM facilities where abuse and vandalism are common. Twelve- and 16-key AVLE keypads feature gold-plated contacts for reliable low-level switching and have individually-illuminated keys.

  1. Permanently engraved metal keys
  2. AVLE offers illuminated models
  3. AVSE models have 12- and 16-key layouts
  4. Sealed to IP 67 for use in industrial environments
  5. Positive tactile feel, more than 1-miilion operations
