Autonics Temperature/Humidity Sensor - THD-WD1-C

Temperature/Humidity Sensor, IP65, 4-wire, Compact design


The THD-WD1-C is a temperature sensor manufactured by Autonics. It has a compact design and is capable of measuring temperatures ranging from -19.9°C to 600°C and measuring humidity levels from 0.0 to 99.9%RH. The sensor has a temperature accuracy of ±1.0°C and a response time of less than 10 sec, making it suitable for various industrial applications. The device requires a power supply of 24VDC and has an IP65 protection structure (except for the sensor part).

Overall, the THD-WD1-C is an excellent choice for temperature sensing applications that require high accuracy and durability. Its compact size and easy installation make it ideal for use in tight spaces or where space is limited.

As a quick report, THD-WD1-C comes with the following features:

  • Temperature/Humidity Sensor type
  • 3-digit 7-segment LED
  • -19.9 to 60.0 °C Temp. measuring range
  • 0.0 to 99.9 %RH Humi. measuring range
  • Output Temperature/Humidity: Current output(DC4-20mA)
  • 500 ms Sampling cycle
  • 24 VDC Power supply
  • P65 (except sensor part, IEC standards) Protection structure


The THD-WD1-C features standard cable type connection. This cable covers the sensor's 4 wires. It is 4 mm in diameter and 2 meters in length.
