ATEN EA1640 Temperature & Humidity Sensor

The EA1640 is a compact, flexible solution for measuring humidity and temperature designed for ATEN's PG PDU series applications where precision matters — from server rooms, data centers, hospitals, smart factories to green offices.
The sensor features 1 x RJ-45 input port, 1 x RJ-45 output port, and 1 x RJ-11 input port for easy connection to the PG PDU series and environmental sensors such as EA1140, EA1240, and EA1340. A terminal block is provided for combining the EA1440 / EA1441 / EA1442 door sensors or the EA1540 capacitive leak sensor. Up to 8 devices are supported in a daisy-chain configuration to expand application possibilities.

The EA1640 was designed with ultimate flexibility in mind and can be placed in an ideal location thanks to the included 1.5 m RJ-45 cable. It also features a magnet for easy attachment to metallic surfaces. Rack mounting kits are included for quick installation in racks.
