Announcing EAO's New S.Series Lite Range of Keypads
Innovative plastic keypads in disguise

EAO, the Expert Partner for Human Machine Interfaces, extends its range of robust keypads with the new S.series Lite – the first plastic keypad to look identical to a metal one. EAO introduces the S.series Lite, an extremely durable keypad which combines the appearance of metal with the advantages of new materials. The S.series Lite looks like a metal keypad, but the keys and housing are crafted from Lexan™, a polycarbonate which is known for its incredible strength and high-impact resistance. It is also protected to IP67 against water, oil and dirt ingress and the metal-look finish is scratch-resistant to ensure long-lasting good looks.

Proving that looks can be deceiving, the S.series Lite is made entirely from an extremely durable plastic.  This keypad offers a simulated matt chrome scratch resistant finish - just like with other more expensive heavy weight models.  This feature ensures a long-lasting fresh, new appearance when used in many types of harsh applications. The S.series Lite is also rated to IP67 sealing standards which protects against water, oil and dirt ingress therefore making it reliable even when exposed to severe weather.

The S.series Lite offers high levels of design flexibility: many different layouts are possible within the two standard sizes, 12-key telephone or 16-key hexadecimal. Each key can be laser etched with any type of legend - characters, numbers or symbols. They can be illuminated with different colored LEDs (yellow and blue offered as standard), either around or through the legend.  The keys themselves can even be finished in different colors (non-standard and subject to volume). High-quality illumination results in numbers that can be keyed easily, even in low-light conditions. Laser etching ensures the marking remains pin-sharp for years. 

Both versions of the keypads can be mounted either from the front or rear using the supplied gasket. They connect through an external pin-header connection.

The robust design of the S.series Lite makes it perfect for use indoor or outside, particularly within vending machines, ticket machines, payment terminals, telephones and access control systems.

The S.series Lite is specially designed for public use, such as vending machines, ticket machines, payment terminals, telephones and access control systems. The S.series Lite has the same dimensions as our standard S.series, can be used outdoors or indoors and has CE and RoHS approval.
