Temperature & Humidity Sensor
EA1640
- A humidity and temperature measuring solution for ATEN PG PDU series
- Supports up to 8 daisy-chained devices
- 1 x RJ-45 input port, 1 x RJ-45 output port, and 1x RJ-11 input port support connection with PG PDU series and EA1140 / EA1240 / EA1340 environmental sensors
- 1 x terminal block supports EA1440 / EA1441 / EA1442 door sensor and EA1540 capacitive leakage sensor
EA1640 serves as a compact, flexible humidity and temperature measuring solution for ATEN PG series PDU applications where precision is significant – from server rooms, data centers, hospitals, smart factories to green offices. The sensor contains 1 x RJ-45 input port, 1 x RJ-45 output port, and 1x RJ-11 input port for easy connection with PG PDU series and environmental sensors including EA1140, EA1240, and EA1340. One terminal block is built for combining EA1440 / EA1441 / EA1442 door sensor or EA1540 the capacitive leakage sensor. Up to 8 daisy-chained devices are supported to broaden applications.
Designed with the ultimate flexibility in mind, EA1640 can be placed at an ideal location as a result of the 1.5 m RJ-45 cable coming with it. In addition, it comes with a magnet for easy attachment to metallic surfaces. Rack mount kits are also included for quick installation inside racks.
