Part #: 1WT_INL_POT_1m_2w
This Inline Potted 1-Wire Temperature Sensor provides a low cost option for temperature monitoring. The sensor head has a diameter of approx 0.25in and the length of the potted section is just over 1in. The rugged jacketed cable is approx 1m long. This sensor is parasitically powered in the 2-wire configuration:
- Brown wire: VDD & GND
- Blue wire: DATA
The epoxy is hardened and highly water resistant, and completely covers the sensor and solder joints, allowing this sensor to be used in harsh conditions.
Multiple sensors can be daisy chained on a single CAT5 network that can extend up to 200 meters or more in a typical environment. The sensors can receive data and power over the same CAT5 cable, which saves time and money during install.
