OBU-M-LCD-S is a surface-mounted metal enclosure, which, given its size and available mountings, is designed for securing mid-size and smaller SATEL made keypads. This robust enclosure protects the device against mechanical damage. It comes with a keylock to prevent unauthorized access to the keypad, which is a good solution if the keypad is to be installed outdoors, in public places or wherever additional mechanical protection may be useful. The enclosure doors are provided with a tamper switch.
