Measured value connectors with Mercotac
Mercotac mercury connected contacts ensure a trouble-free and wearproof transmission for signals and currents up to
30A. Thanks to their extremely low resistance values, these rotary connectors are particularly suited to the measured
value transmission of:
thermoelements, instruments, antennas, static discharge, etc.
The Mercotac housing is made of rustproof material with specially applied sealing elements and protected to IP66.
