1 PRODUCT DESCRIPTION
- IP 69K protection class, IK 05 impact strength
- operating temperature from -25°C to +85°C
- long lifetime of more than 20 million actuations
- with mounting accessories: keypad is sealed into the
housing with IP 68 protection class, mounting into the
housing from the front or the rear
- as standard: keypads are available as a number block
with 12 or 16 keys and with an aluminium front
- point illumination may be integrated into the individual
key fields as optical feedback or for user navigation
- the operating panel can be designed in several colours
in both the aluminium and stainless steel versions
- the keypads can be adapted to customer requirements with respect to the outer geometry as
well as to the number and arrangement of the keys
- particularly suitable for use in outdoor applications due to their ability to resist extreme ambient
conditions such as negative temperatures, ice and snow
- completely sealed operating panel is easy to clean and resistant to common cleaning agents
Operation principle:
The piezo keypad is based on the principle of the piezoelectric effect. By pressing, a piezoceramic
generates a voltage pulse. The power of the voltage pulse is amplified from the integrated electronic
circuit to a bipolar switching output.
During the voltage pulse the electronic is switching for the specified pulse duration. The The
switching time of the electronic switching output depends on the actuation force and the operation
speed.
Connection diagram of a single switch NO (Normally Closed):
In the unactuated condition, the piezo ceramic is in a high-impedance state and the switch has an
output resistance greater than 10 MOhms. If the piezo-ceramic is actuated, the output resistance is
reduced to a value smaller than 20 ohms.
This corresponds largely to the functionality of a conventional mechanical switch.
