Conventional electromechanical switches have moving parts that inevitably wear out.
The reliability of electromechanical switches can be reduced with contaminants such as moisture and dust that will form faulty points of contact.
The solution is a piezoelectric switch with no moving parts.
The switch is not sensitive to polarity: the (+) and (-) cables can be reversed without any risk.
How a piezo switch works:
The surface transfers to a piezoelectric disk the pulsation variations creating an electrical pulse.
This electrical signal is converted to another electrical signal present at the output through a customizable electronic circuit.
The duration of the electrical signal depends on the speed, strength and duration of the action.
The output of the switch is closed by a pulse of specific duration depending on the electrical function chosen.
In the case of this model it is a momentary contact. At the exit we have a simple pulse of short duration
They work with very low Currents of 5mA or less and support up to 200mA, but it should always be used below this maximum
Very important: Do not exceed the Current and / or maximum voltage (s), deteriorate and can not be used again
Working voltage: 5 ~ 24 Vac / dc
Maximum Current: 200 mA
Resistance ON: maximum 10 ohms
Resistance OFF: 5 Mohms minimum
Operating force: 6..15 N
Life: 50 million cycles
Case: anodized aluminum
Cable length: 300mm (AWG24)
Diameter: 16 mm
Isolation: IP68 (IEC529) IP69K (DIN40050-9)
