APEM offers a line of switches, keypads and keyboards based on the principle of the piezo effect. Dust and waterproof, these products are particularly suited for harsh environments. Their metal surfaces are resistant to abuse (flames, glue, foreign parts, detergents, hydrocarbons etc). Also, constructed without any moving parts, a life expectancy of 50 million cycles is guaranteed.
The piezo switch range comprises: a standard models with 16 mm or 22 mm diameter bushing, round or square operator, illuminated or non-illuminated; a programmable model; custom-made switches from a large choice of options (dimensions, material, colour, markings etc.).
The piezo keypad and keyboard comprises: standard 12, 16 or 20 key keypads; 104 key AT/PS2 keyboards; standard access control systems; custom-made keypads and keyboards ranging from minimal solutions of 2 keys per keypad to large keyboards in various colours, designs and sizes, with cables and connectors to customer specifications.
Typical applications: beverage dispensers, lifts, safety and security equipment, public internet and information kiosks, mining, chemical and petrochemical industry, food industry, and medical equipment.
Main specifications:
* Electrical functions: momentary NO or NC, continuous NO or NC, toggle.
* Standard rated current: 200 mA (up to 2 A on some models).
* Operating temperature: -20 to +75°C (-40 to +125°C on request).
