What is the Honeywell AF00-B54?

Outside Temperature Sensors by Honeywell contain a single sensor element, and are used to detect outside temperature in heating, ventilation, and air conditioning systems enabling weather-related temperature control. The innovative mounting concept with a mounting bracket (which ensures that the housing is held at the proper distance to the mounting surface for correct measurement) allows for easy installation and unbiased detection of ambient temperature. The sensors are suitable for use in systems using Ni 1000, Pt 1000, NTC 10k, or NTC 20k temperature sensing elements.
