700/900 Series
– Sealed & Rugged Keypads
In demanding or hostile environments, a
keyboard operator must be confident that data
can be entered quickly and accurately. With this
objective the keys move with a positive
over-centre action ensuring rapid and reliable
data entry even in the most extreme conditions.
Storm 700 & 900 Series keypads are supplied
in 4, 12, 16, and 36 key configurations.
The keypad’s unique modular design enables
combinations of keypads to be used in the
construction of more complex keypanel layouts.
This design feature is especially useful when
the keypads are used in conjunction with the
Storm Universal Keypad Encoder.
The exceptional reliability of Storm
keypads is achieved by an ingenious
but simple method of construction.
A moulded rubber mat is secured
around a rigid circuit plate providing
its own environmental seal. Storm
keypads have been successfully
tested after submersion under 1
metre of water for periods in excess
of 1 hour. This was achieved
without using gaskets or sealing
compounds of any kind.
Interchangeable keytop legend tiles allow
the selection of keytop graphics to suit any
particular application. A comprehensive range of
keytop legend tiles, are available from your
local Storm supplier.
Storm keypads are available in non-illuminated
(700 Series) and illuminated (900 Series) versions.
The keypads can be easily mounted to a flat
surface or can be located beneath a suitable
aperture in a fascia panel.
STORM 900 Series (illuminated)
4, 12 and 16 key formats only
Using the impressive refractive properties of
silicone rubber, and the latest developments in
surface mount technology, individual keytops can
be illuminated by twin diode, two colour LEDs.
The keypad’s surface can be lit with a low level
green illumination. This provides clearly legible
keytop graphics and a visual indication of the
keypads operational boundaries. In addition,
individual keytops can be selectively lit with a high
intensity red LED providing positive status
indication or software controlled "user prompts".
