Tough keypad for product designers

15 November 2006 Switches, Relays & Keypads

A rugged keypad that is said to combine 'strength, versatility and beauty', is availableÿfrom EAO. The S.series keypad is suited for any application that requires a key-entry control, including access control systems, industrial machinery, banking terminals, public telephones, kiosks and vending machines.

It is highly tactile and reassuring to use, and also reliable and hard-wearing for harsh environments, such as outdoor and unsupervised locations, according to EAO. The S.series keypadÿoffers design flexibility from a standard product and can be customised to suit the environment of the application.

The keys on the S.series keypad can be engraved with a range of standard symbols or ones specified by the customer. The keypad and individual keys can be illuminated in white, blue, red, yellow and green, or a combination of these colours; halo illumination around the keys is also a possibility.

It can be supplied with either a 12- or 16-key layout, and there is a choice of standard, telephone, or hexadecimal configurations. It is available in a natural finish or black. The metal-bodied S.series features a front plate and anti-pull-off keys constructed from ultra-tough Zamak. It is sealed to IP67 and it will resist heat, shock and vibration. It is tested for quality to 4 million operations.
