Can you recommend a keypad?

Can you recommend a keypad entry device for my home in Hawaii, meeting the following specifications?

Standalone touch keypad
Output is a contact closure, for low voltage control to my existing gate controller
Either 24V power or you include a power supply
Tropical exterior use (316 stainless steel construction)
Includes a stainless steel mounting stanchion, for use at driveway
Lighted face

I am looking for best quality

(Note: Intercom is not required)

2. Also, can you recommend a packaged exit loop controller, whose sensor wiring will be mounted in or under the concrete exit slab. Output should again be a contact closure to operate my existing gate control.

Thank you in advance.
