Part #: 1WT_6SSP_1_5m_3w
This low cost sensor has a 1.2 inch long stainless steel probe and a 5m long jacketed cable with 3 conductors wired to a DS18B20 chip.
Since this sensor uses the 3-wire configuration, you have the option to connect the sensor in 3-wire mode with a separate Vdd wire or you can tie the Vdd wire and the Data wire together to connect the sensor in 2-wire mode, which is used when powering sensors parasitically.  Having all 3 wires available provides a flexible design that can be used in a wide range of temperature measure applications.
 
The 1-wire sensor element used is the DS18B20 with 12-bit resolution.
 The probe is only 1.2" long and has a diameter of 6mm.  The 3-wire cable is 5m long.  This sensor is suitable for both Non-Parasitically powered and Parasitically powered implementations.
Red wire: VDD
 Yellow wire: Ground
 White Wire: DATA
 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.
