This technical note describes the parts, wiring, and dimensions of the Vaisala HMDW110 and HMDW80 series humidity and temperature transmitters that use an M12 connector. Other transmitters in the HMDW110 and HMDW80 series use cable gland and screw terminal wiring, but the functionality of the transmitters is otherwise the same.
For full instructions on installing, using, configuring, and maintaining HMDW110 series and HMDW80 series transmitters, see the following documents at the Vaisala documentation portal docs.vaisala.com:
