536-778 | Outside Air Temperature Sensor, 100K Ohm Thermistor | Siemens

This outdoor air sensor provides input for cost-effective, accurate temperature sensing via an 18 AWG twisted, shielded cable pair. The sensor resistance varies proportionally to the temperature being measured and has a 100,000 Ohm reference resistance at 77 degrees Fahrenheit. This sensor allows through-the-wall mounting for outside air temperature measurements and has a temperature range of 0 to 120 degrees Fahrenheit; uses metal housing.
