Johnson Controls A99BB-25C Temperature Sensor

The Johnson Controls A99BB-25C Temperature Sensor is a precise Passive Positive Temperature Coefficient (PTC) device designed for reliable temperature monitoring in refrigeration and HVAC applications. This splashproof sensor delivers consistent readings in demanding environments, making it ideal for commercial chillers, freezers, and climate-control systems.

Key specs include a temperature range from -40 to 212 °F, accuracy of ±0.9 °F, and a stainless steel probe with a silicon wetted material for durability. The unit features a PVC cable, 9-3/4-inch length, and 22 AWG lead wires, designed for easy installation and robust electrical performance. Operating temperature mirrors the sensing range (-40 to 212 °F), with storage tolerance up to -40 to 221 °F.
