Rope sensor for rolling shutter with piezoelectric switch (Duevi patent) that opens the output in a clean and regular way without mechanical bounces, with opening pulse of about 7ms .
This technology improves pulse counting and avoids all critical problems of the mechanical model: missed alarms, permanent opening of the contact for slimming or thermic dilatation, contact oxidation. The rope guide can also rotate of 360°.
Compatible with magnetic contacts MINI-C and CTSR, expansion cards ESP8-2 and ESP8-BUS.
If the control panel does not manage directly fast inputs (ms), an additional analysis/ pulses counting card is necessary (not
provided).
Note: Opening pulse can be modified upon request up to 15ms (min. 100pz / delivery about 40days from order date)
