PTC Temperature Sensor

Eliminate signal drift in your refrigeration circuits. The Johnson Controls A99BB-200C is a passive PTC silicon sensor engineered for absolute thermal stability in volatile HVAC environments. Featuring a stainless steel probe and a 2-meter (6.5ft) PVC cable, this unit delivers precise feedback across a -40°F to 212°F range. Ideal for freezers, display cases, and defrost termination where moisture resistance is non-negotiable.
