The top cover is recessed to allow a membrane keypad to be flush mounted, and PCB standoffs are provided in the top and base. The IP65 environmental sealing is achieved by a rubber gasket in a slot in the base. The top and base are assembled with four screws that locate into brass inserts in the top molding, facilitating repeated access to the housed electronics. The fixing positions are outside the gasket, ensuring the integrity of the seal. An integral end panel forms part of the top cover, providing an easy to machine area for cable entry, switches and indicators.
