Using the S.series keypad that is constructed from ultra-tough Zamac, the company can design a stylish and distinctive keypad solution tailor-made for applications within demanding and harsh environments. The standard products within the S.series range include 12 or 16 key keypads with a choice of telephone or hexadecimal II configurations. There are extensive possibilities for customization, including "halo" illumination. This style presents the illumination around the character on each key in a range or combination of colors. A library of more than 20 different illuminated key characters are available as part of the standard offering. A character-design service is also available if special markings are required, as well as laser engraving facilities for non-illuminated keypads (subject to minimum order quantities).
